Every time you get in a car, pick up the phone, handle a tool or turn on an electronic appliance, you are looking at the result of metal fabrication.

Our economy relies on metal fabrication. Without it, we wouldn’t be able to run our electrical systems or create the parts that keep our houses, kitchens, businesses, computers, and vehicles operational. However, it is difficult for many of us to understand what metal fabrication entails, as well as all of the areas of our lives it affects.

This article will explain the essentials of metal fabrication: its definition, history, process, benefits, types, and applications. By the end, you will have a more in-depth understanding of how crucial this process is to civilization and how many different parts of our lives it touches.

What Is Metal Fabrication?

Metal fabrication is the process of manufacturing sheet metal to make it conform to specific shapes. It takes place through cutting, stamping, shaping, folding and welding.

The sheet metal fabricators use is typically around a quarter of an inch or less. At this thickness, the metal is pliable and can easily assume different shapes. The metal fabricators themselves are highly skilled specialists, trained to cut and manipulate metal with a surgeon’s precision. Many manufacturing operations operating on a grand scale will have their regarding onsite metal fabrication crew.

Many jobs outsource metal fabrication to machine shops. Machine shops exist all over the United States — and the rest of the world, of course — and they often operate by creating schematics to bid on jobs for companies. The work can vary widely, from medical to building materials to computers, but the beginning phases can look similar across industries.

Metal fabrication requires a lot of strategy and planning before actual work commences. The process is far more than just taking drill bits to sheet metal — there is engineering, bidding, back-and-forth communication with the client, adjustments, material sourcing and material ordering. Additional parts that go into the process may include:

  • Plate metal
  • Expanded metal
  • Formed metal
  • Wire for welding
  • Hardware
  • Fittings
  • Castings

Of course, these will vary depending on the job. Essentially, a fabrication shop or machine shop will start with a collection of assorted metals and transform them into the tightly built structures so common in our everyday lives.

The History of Metal Fabrication

Humans have been mining and machining metal for the past 10 millennia, as evidenced by a copper pendant archaeologists found in northern Iraq that dates back to about 9,000 BCE. Fabrication shops as we know them today began to exist around the Industrial Revolution, when sheet metal was in much higher demand than before. The invention of the hydraulic press, which allowed manufacturers to apply unprecedented pressures to pieces of metal, transformed the metal fabrication industry.

Metal fabrication on a broad scale was necessary to form systems of railroads, telegraph lines, weapons, tools, printing presses and other implements that have been so instrumental in our history. All of these advances relied on machine shops performing joints, cuts, bends and forming operations, just as is done today. The advent of compressed air has made riveting, another important part of fabrication, much easier and more efficient.

With the onset of the 20th century, metal fabrication has assumed an even larger role in our lives. We now perform machining on grand scales, ranging from small, family-run operations to large manufacturing plants employing thousands of people.

How Does the Metal Fabrication Process Begin?

Metal fabrication starts with an idea, typically born out of necessity, that involves a piece of metal suited for some particular task. For example, a tech company may need a machined aluminum case for a new gadget. Their engineers design the part and send it out to several machine shops as part of a request for a quote. The machine shops analyze the schematic, calculate the cost of production and reply with both cost and lead time.

At this point, the company chooses the machine shop they wish to work with. The shop then puts the order in their queue and sets about ordering materials for the machining job. These may consist of sheet metal, metal bars, metal rods and more. As soon as the parts arrive and the job is in the queue, the team sets to work building the part itself.

The time it takes to fabricate depends on the complexity of the part and the demand on the machine shop. The fabrication shop may also provide assistance in both design and production, though this is more common for custom parts that require unique processes to complete. Skilled machinists can produce practically any shape or design once they figure out the best way to solve the problem.

Problem-solving includes conceptualizing the best way to create the part, which may mean figuring out what material characteristics are necessary to accomplish the design. Computer-aided design has made parts much easier to fine-tune, and it allows engineers to figure out crucial information instantaneously, including information on spots that may be structurally weak.

What Is the Metal Fabrication Process?

The actual process of metal fabrication begins with choosing the right method. This will vary with the geometry of the part, the type of usage it will get and what it is made of. Here are examples of some choices for different metal fabrication processes:

  • Cutting: This is the most fundamental process in metal fabrication, and it can be accomplished through waterjet and laser cutting, chopping, sawing, shearing and chiseling. Cutting is what turns the sheet metal into a piece of the required size and shape. Today, waterjet and laser cutting comprise the foremost technologies available.
  • Casting: A die forms a mold, and the fabricator pours molten metal into it. This metal cools down and turns solid, and the part remains after removing the die.
  • Forging: High-pressure machinery compresses raw metal, allowing a fabricator to bend and shape it.
  • Punching: Turrets punch pre-designed patterns into the metal, either for decorative purposes or utility.
  • Drawing: This process uses tensile force to pull liquid metal into a tapered die.
  • Milling: A milling mechanism bores perforations into the metal, which, due to the nature of the machine, can be non-circular.
  • Drilling: A drill cuts holes into the metal using a circular bit.
  • Turning: The piece of metal goes onto a spinning platform, allowing a technician to cut it radially with a tool as it spins.
  • Extrusion: A ram forces billets through a die. This extrusion process forms cylindrical parts, such as pipes or electrical wires.

After the initial process turns out the resulting part, it is possible a secondary finishing process may be required. This may be some sort of assembly if two or more parts need to be joined. The part may also need deburring, grinding, riveting, adhesive application, bolting or painting.

Benefits of Metal Fabrication

There’s not much need to sell anyone on metal fabrication these days. Metal has demonstrated its aesthetic quality, longevity and structural strength for millennia now, and with new alloys continuing to emerge, it is only continuing to improve. Here are some of the benefits of metal fabrication:

  • Superior strength: Metal is a cut above the rest in terms of its strength. Particularly important is its high tensile strength, or resistance to being pulled apart, that makes it useful for wires, cables, screws and other hardware. It also demonstrates great compressive strength and nearly unparalleled hardness. All of these qualities come coupled with the fact that metal is easy to manipulate, bend, drill and shape.
  • Stronger than plastic: Plastic is metal’s main competitor. However, while plastic is suitable for certain applications, there is a compelling reason metal often wins out: It is vastly stronger. Metal is also more durable and more resistant to wear than plastic. If there is a risk of high temperatures, metal also wins in that it can handle a range of temperatures that would cause most plastics to melt. Metal can also undergo a wider range of manufacturing processes than plastic.
  • Aesthetic quality: There is hardly a product in the world that doesn’t benefit at least partially from aesthetic quality. Whether it is a consumer product or a piece of industrial equipment, metal bespeaks strength and smooth operation. We largely associate our perception of its beauty with its advantages — that’s why the latest technological revolution has mostly centered on sleek, elegant metal forms such as laptops and smartphones.
  • Heat resistance: Beyond its comparison with plastic, metal is capable of withstanding dramatic increases in temperature. Assuming the manufacturer has accounted for the expansion that results with increased temperature, this heat is unlikely to damage the metal part.
  • Versatility in fabrication: Metal can withstand lots of different manufacturing processes. These include deep drawing, forging, casting, welding, soldering, chipping, peening and more, making a wide array of metal shapes and geometries feasible. The sky is the limit with what parts will be required in the future, so metal will likely remain the material of choice.
  • Cost-efficiency: Particularly in high-volume production, metal is extremely cost-efficient. Machine shops can replicate procedures and create large runs of product for relatively little cost per unit.

Metal Fabrication Applications

To give some idea of the breadth of industries where metal fabrication is an indispensable tool, let’s take a look at the applications of fabrication in everyday life:

  • Automobile bodies: Automobiles may contain plenty of materials, but their skeleton and skin are completely reliant on metal. A car’s chassis is metal, typically steel or aluminum, as are most of its exterior panels, suspension riggin, and frame. Without metal, a car would not have the structural integrity to handle bumps on the road or heavy cargo.
  • Automobile engines: Automobile engines consist of tightly machined parts that interlock to form a functioning whole. Metal fabrication techniques make everything from the long, snaking pipes of the exhaust system to the crankshaft and pistons. Other components include the crankcase, oil pump, spark plugs, fuel injection system, chain, throttle and gudgeon pin. Bolts and rivets hold most of these components together, which also rely on metal fabrication.
  • Tools and hardware: Our homes, automobiles, appliances and everyday conveniences would not exist as we know them without metal fabrication. That is thanks to the fact that the majority of our tools and hardware get produced by machine. Hammers, air compressors, nail guns, drill bits, grinders and saws are all the result of metal fabrication. Of equal importance are the pieces of hardware they are responsible for installing, such as nails, screws, bolts and tension rods.
  • Smartphone and laptop shells: The computers and phones we have come to know and love are the results of metal fabrication. Particularly with the popularization of simple, sophisticated products that have served to tame the growing complexity of user interfaces, a phone or laptop’s case can, in many ways, define it as a product. For instance, what would the iconic iPhone be without its smooth backing of anodized aluminum and stainless steel?
  • Kitchen hardware: Look around your kitchen, and you will soon realize all the tiny, fabricated parts that make it functional. There are metal handles on the cabinets and drawers. Hinges and drawer slides make the cabinets open and close easily. Faucets and entire sinks are made from low-maintenance stainless steel. Toaster ovens, tea kettles, stove grills, vent fans, refrigerators and trash cans — metal fabrication makes all these things possible.
  • Gadgets and electronics: Electronics rely on metal fabrication for more than just their shells. Fabrication is responsible for creating wires of different sizes and materials, as well as piping and internal architectures that allow for the placement of circuit boards and components. Cooling fans and parts like potentiometers are also often made with metal fabrication.
  • Aerospace: One growing sector of industry is aerospace, whose components and craft must follow tight tolerances and uncompromised integrity. These parts must withstand sustained use, extreme temperatures, pressure fluctuations and chemical exposure — the perfect job for metal. Metal fabrication jobs for aerospace range from large, industrial plants to smaller operations specializing in a specific part or component.
  • Medical: The medical industry and the metal fabrication industry are inextricably connected. From hospital beds to surgical tools, and from ventilation systems to lifesaving defibrillating devices, metal fabrication has helped build the medical industry. Metal is also advantageous to this industry because it provides an easily sterilized material that does not trap bacteria, moisture or germs.

There are many cases where traditional cutting won’t work for a project and only laser cutting will achieve the desired results. While laser cutting is a fantastic cutting method for a wide variety of industries, some businesses are quick to consider implementing it on-site. Even though buying your own laser cutting equipment and handling the process on-site may sound like a good option, it’s not the best choice for many businesses. Instead, consider outsourcing your laser cutting to a third-party company. Read on to learn more about why outsourcing may be right for you.

Reasons to Outsource Laser Cutting

While many businesses may consider buying their laser cutting equipment outright and handling everything on-site, the cost of this equipment is even more prohibitive than it seems. As such, many businesses are better served by outsourcing laser cutting to a third-party service. Here are just a few advantages of outsourcing laser cutting:

  1. Expensive Equipment: Laser cutting equipment is prohibitively expensive, especially for smaller businesses that won’t use it often. While some machining businesses can justify the costs, most businesses needing laser cutting services don’t need a laser cutter taking up space on the production floor. Instead of doling out the money, outsource your laser cutting to a company who can get the job done while meeting your budgetary needs.
  2. Required Expertise: While laser cutting is a popular and highly-regarded technique, not many people know how to handle the equipment. There is a significant learning curve to navigate. To use a laser cutter, employees need extensive training. Instead of paying for that training, outsource the job to a group who already knows how to use the equipment properly.
  3. Costly Maintenance: Laser cutting equipment has complicated parts that require constant maintenance. Paying for this maintenance can be very expensive, but skimping can be dangerous for the equipment and employees. This is another reason why outsourcing your laser cutting services is cost-effective in the long run.
  4. Make the Most of Laser Cutting Businesses love laser cutting for many reasons. It’s precise and effective and can be used on a wide variety of materials. However, you can maximize these benefits by having your laser cutting done by a team of experts. This is a primary reason why many choose to outsource their laser cutting — they benefit from the experience of experts who can make the most of laser cutting and maximize the benefits of this cutting method.

Consider these reasons to choose to outsource laser cutting services and see how they may benefit your business and reduce your costs. To learn more about these benefits and what you can gain by choosing outsourced laser cutting, contact Laserfab.

The two most common cutting practices used by manufacturing companies are laser cutting and waterjet cutting. While not always appropriate for the same applications, these two fabrication techniques offer value to manufacturing processes, albeit in different ways. To understand this more fully, it’s essential to understand the methods themselves and the differences between them.

What is Laser Cutting?

Laser cutting is a metal cutting process that makes use of high-density energy beams, usually produced with gas. These beams of energy are directed by mirrors to cut into materials. The beam vaporizes materials on contact, creating smooth, clean cuts while avoiding warping and tearing that can happen with other cutting techniques.

What is Waterjet Cutting?

Waterjet cutting primarily differs from laser cutting in its methods — instead of a laser beam, a waterjet is used to cut material. This waterjet contains abrasive materials like aluminum oxide or garnet to help improve cutting ability, creating cuts through abrasion rather than vaporization.

Differences Between Laser Cutting and Waterjet Cutting

The differences between these two methods don’t just lie in their methods, but in their results and applications. When choosing between laser and waterjet cutting in your applications, consider the following:

  • Materials: Both laser and waterjet are excellent choices to cut metals (stainless steel, steel, aluminum, copper, brass, bronze etc.). Any required secondary operations will help determine which technology is the best for the job.
  • Precision: Laser cutting delivers extremely high precision, reaching tolerances of +/-0.005″, depending on the speed of the laser. Waterjet cutting typically holds a tolerance of +/- 0.03″.
  • Waste: Both laser and waterjet produce little waste. Depending on the material type, there can be deburring needed with laser cutting, but very little clean up required for parts cut on the waterjet.
  • Tooling: Fiber laser cutting maintains a low tooling cost, since the gasses used to produce the laser and the components are inexpensive. Waterjet cutting is comparatively expensive, requiring many components to run properly, including a high-pressure pump, abrasive materials and cutting heads.
  • Speed: Laser cutting is capable of cutting between 50 – 2,000 inches per minute, depending on speed and material thickness, while waterjet cutting is capable of up to 100 inches per minute.

In the end, each of these material fabrication methods has its own advantages and disadvantages to understand as you select your preferred method. If you need assistance deciding between custom laser cutting vs custom waterjet cutting, Laserfab can help!

If you have ever considered stainless steel for a project, you know it’s a high-quality but costly material to manufacture with. While this material can seem expensive compared to other metals, however, the cost represents a value that no other materials can provide. Stainless steel offers numerous benefits to engineers and designers, from long-term value to range of applications. To understand these pros of steel fabrication, we’ll take a look at stainless steel a little bit more closely.

What is Stainless Steel?

Stainless steel is an alloy of iron and chromium, coming in 60 varieties, or “grades.” The minimum 10.5% chromium produces a thin, invisible layer of oxide on the surface of the steel called the “passive layer.” This layer allows the stainless steel to be corrosion-resistant, healing in the presence of oxygen.

Reason to Use Stainless Steel Fabrication

The nature of stainless steel lends numerous advantages to steel metal fabrication over other materials, including the following:

  • Long-Term Value: While the high upfront cost of stainless steel may be offputting for people who aren’t experienced with the material, the longevity and long-term value this material provides are unparalleled. This maintenance-free material allows designers and engineers to focus on design and production without considering maintenance in the process.
  • Versatile: Because it is available in so many grades with specific qualities, stainless steel can be used in a huge range of applications. From cooking supplies to surgical instruments to airplanes, stainless steel is used everywhere to meet a variety of strength and corrosion-resistance needs.
  • Heat Resistance: The resistance to fire and heat exhibited by stainless steel also adds to its long-term value and versatility. Specifically, high chromium and nickel alloy grades are particularly heat resistant, making them perfect for applications like boilers, valves and heat exchangers.
  • Corrosion Resistant: Stainless steel is resistant to corrosion due to its oxide layer. With this layer, it retains its surface quality in nearly any setting, contributing to the material’s long-term value.
  • Easy Fabrication: Provided that your fabrication company is using the latest in modern technology and equipment, fabrication should not be a problem with stainless steel. Most modern stainless steel fabricators can carry out cutting, welding, and everything in between with ease, provided they’re not using outdated equipment.
  • Recyclable: With an increasing emphasis being placed on sustainability, environmental-friendliness, and ethical resource management, the recyclability of stainless steel has become an enormous benefit. Stainless steel is often recycled, and today, over 50% of stainless steel comes from previously melted stainless steel scraps. This helps keep steel waste to a minimum.

It’s easy to see how the pros of steel fabrication far outweigh the cons, especially if you are considering steel for its long-term value.

All About Laser Cutting

In the last few decades, laser cutting has experienced more than a surge in popularity — it has become an indispensable part of world commerce. From fabrication to medicine and beyond, laser cutting is an industry seemingly without limits. Its products can be found everywhere. Lasers cut the silicon in microchips, perform corrective eye surgeries and craft the futuristic gear hurtling into space aboard rocket ships.

Still, there is a lot about laser cutting that most people still don’t know. How does it work and what are the mechanics behind it? What are all of its applications? What is the laser cutting process and how do you use it for your own project or business?

In this article, we will dive into everything you need to know about laser cutting. There is a lot to learn, starting with the technical aspects of how a laser cutter functions and then moving on to its many uses. Luckily, the technology is as accessible to the mind as it is to the consumer. Let’s get started.

What Is Laser Cutting?

Simply put, laser cutting is the process of using a laser to cut, score, engrave or otherwise alter physical materials. As futuristic as it sounds, laser cutting is a technology that has been with us for decades. Like many innovations, its scope was initially limited, but an incredible number of industries have since adopted it with great enthusiasm.

It can be easy to operate a laser cutter these days. Though the technology itself is the result of astounding feats of genius, the user interface has developed in a user-friendly way. It is common for hobbyists, school science classrooms and businesses to employ the use of laser cutters. They’re not just useful — they are a spectacular way to learn about optics and the properties of light.

Laser cutting starts, naturally, with a laser beam. The beam is focused until its intensity is sufficient for the job at hand, whether that’s cutting through metal, human tissue or cardboard. A computer program guides the laser itself and specifies the pattern the laser beam will cut. Once it begins, the laser will then follow the pre-programmed guide to complete its work.

Depending on the material and the desired result, the laser beam will both move around and vary its focal length. This way, it can reach different depths and cut different layers of material. With metals, this is useful for techniques like engraving. In other applications like medicine, however, its pinpoint accuracy allows it to cut medical devices.

Laser cutting is truly an amazing technology. It lies at the confluence of computers and the human touch. Its applications are already broad, but more will undoubtedly emerge as technology continues to improve.

Let’s look now at the mechanics of a laser cutter and how it does what it does.

How Does Laser Cutting Work? Here Are the Basic Mechanics

The word “laser” stands for “Light Amplification by Stimulated Emission of Radiation.” In a laser cutting device, it all starts with the laser resonator. This component creates the laser beam, in which light particles of the same wavelength travel out of the resonator in the exact same direction. This beam might be in the invisible infrared area of the spectrum, in the case of a CO2 laser, or of some other wavelength as required by the application. When it exits, it may be about .75” in diameter.

This beam of parallel light waves is then reflected off one or more mirrors into the focusing head. Once inside the focusing head, the beam is sent through a series of lenses. These, predictably, focus it. It then passes out through a nozzle and sears whatever it lands on. You’ve seen this effect before. In the same way that sunlight through a magnifying glass can start a fire, shining a laser beam through a focusing lens creates an incredibly powerful, singular point of light.

That means all the photons in the laser beam converge at a single point. How could this be? The more physics-oriented reader may cry, “Pauli Exclusion Principle!”, which roughly states that two particles cannot occupy the same space at the same time. However, since photons are not technically matter, they are exempt from the Pauli Exclusion Principle and can exist at the same point in space. That means all the energy in that .75” laser beam is now focused into one point in space.

You can imagine what happens next. The point on the material where this intense light strikes is instantly melted or vaporized.

What Happens to the Material During Laser Cutting?

We have an incredibly intense confluence of laser light striking a surface. But what happens next? How is the depth of cutting controlled and how do we account for different types of material?

As it turns out, we left out one component of the laser system above. It’s the addition of compressed gas to the laser beam’s path. As the beam converges past the focusing lens, it is joined by a stream of fast-moving gas. This is typically oxygen or nitrogen. The gas flows downward and shoots out of the nozzle, which the laser also passes through the tip of, and impacts the zone where the laser is cutting.

Oxygen might be used for a material like soft steel, which the laser will cause to ignite. The oxygen will then make the burning steel incinerate and disappear from the site. In other metals such as aluminum or stainless steel, where the laser beam simply causes the metal to melt, nitrogen is used. As the metal melts, a jet of gas blows down with it and removes the molten metal from the kerf.

The kerf is the slit made by the laser. Its width is adjusted by focusing the laser at different heights relative to the surface.

Uses and Applications of Laser Cutters

As we have said, laser cutting is an exciting industry full of continuously new developments. Here are some of the most common applications of laser cutting today.

  • Metals

Not only does laser cutting work on a large number of metals, but it is also a versatile tool between industries. Laser cutting can make smooth, tight cuts that are cleaner than those made by machining. Like machining, it too can be programmed and guided by a computer, meaning a laser cutter can automatically create large numbers of metal parts for cars, computers and more.

Metals undergo many different operations in laser cutting. Often, strange shapes such as automobile frames or hydro-formed parts need laser cutting, as do many parts in the aerospace industry. The results are often better than with plasma cutting.

  • Reflective Metals

Why mention reflective metals when we’ve already mentioned metals? Because reflective metals bounce backlight that shines upon them, which this raises concerns when directing a high-powered laser beam at them. If the metal were to reflect the laser, it could destroy itself.

The answer to this problem comes in the form of fiber laser cutting. With this technique, fiber optic cables transmit the laser beam to the metal. Any light reflected does no damage to the fiber optic cable. Metals such as aluminum, silver, copper, and gold are all reflective and are vitally important in the production of automobiles and semiconductors.

  • Medical Sciences

Laser cutting also plays a huge role in the medical industry, where extreme precision and tight dimensional tolerances are essential. Because of the medical industry’s demand for high volume, this technology aligns with their needs in that it can replicate designs with both accuracy and a quick turnaround.

Medical devices of many types have their origin in laser cutting, from cardiovascular and orthopedic devices to components for surgical implants. With laser cutting, these devices can be made with the required rapidity without sacrificing accuracy.

  • Engraving and Marking

A slightly less graphic application of laser cutters can be found in the world of engraving and marking. This is also where the laser cutter frequently enters the mainstream market. Many metal signs, insignias and other metal works are produced through engraving and marking. When jewelers need an engraving, they frequently turn to laser cutters.

However, the process is not just limited to metals. Wood also responds well to laser cutting. Wooden signs, pictures, and even decorative topographical reliefs are all products of this technology.

  • Silicon

Our world very much runs on silicon. It makes up our microchips, our solid-state semiconductors and a host of other things related to computers and electronics. It is also a large player in the important field of solar energy, which has a growing potential to power our world. Laser cutting is one of the primary ways silicon is cut for use, so it is difficult to exaggerate exactly how important the technology is.

Part of the reason technology consistently shrinks in size and increases in capacity is thanks to laser cutting of silicon. Laser cutters have grown increasingly precise — as a result, they can cut smaller and smaller pieces of silicon.

The Benefits of Laser Cutting

Laser cutting is an incredible technology that serves a huge chunk of the world’s industries. Its benefits continue to grow in number as the technology improves and as more applications find it useful. Here is a list of reasons why it is so popular at the moment:

  • It is versatile with respect to materials. Laser cutting is not limited to any one material or even subset of materials. Laser cutting works with a huge number of metals, ceramics, woods, plastics, rubbers, silicon and more, and is finding new applications all the time.
  • Kerf widths are narrow for fast and accurate cutting. The kerf width in laser cutting can be incredibly thin, which means less material is wasted, the cuts are more precise and efficiency is higher. The turnaround times in laser cutting are relatively quick, too. Additionally, shapes, patterns, and operations can be repeated accurately. The robotics involved in laser cutting are highly sophisticated. If a process requires automation or repetition, you can be sure laser cutting will produce high-quality output.
  • The technology is reliable and setup time is short. Laser cutters have become extremely reliable thanks to improvements in technology, meaning you don’t have to worry about your systems failing. This prevents backups and delays. Programs make designing your product quick and easy.
  • If you need to make a change mid-production, it is easy to do. If you find out at some point during production that you need more, less or a slightly different variation of a product, laser cutters can pivot quickly and adapt to the change in demand.
  • Processing is efficient. If you want to do multiple jobs at once, overlap projects or do some other variation on the norm, laser cutters can accommodate the request.
  • There is no need to clean most materials after laser cutting. Unlike many other processes, laser cutting does not leave a mess. You won’t have to deburr or sand-down your products because the laser cutting process leaves it smooth. In many cases, you can pull the product out of the cutter and send it off to be shipped.
  • The technology is always advancing and becoming greener. Laser cutters are energy-intensive, but they are becoming vastly more efficient. Additionally, CO2-based lasers are increasingly being replaced by fiber-optic lasers.

All About Waterjet Cutting

Those who have operated a pressure washer know the incredible cutting power of water. Waterjet cutting, which uses a stream of water to cut through metal, stone and other solids, takes this concept to the next level by using water pressure more than 20 times higher than that of a pressure washer.

This technology came about in the 1970s and has advanced rapidly ever since. With the aid of computers, waterjet cutting has become a necessity for many industries. It is one of the most versatile processes for cutting shapes and has a narrow kerf width, which gives the cutter more agility. For this reason, it is often best for detailed work and can produce figures that are quite small.

As opposed to laser or plasma cutting, both of which involve high-temperature streams of energy, waterjet cutting is done entirely with water and an optional grit. It is a cold-temperature process, which is important in several ways, but most notably, it forms a different type of edge than its hotter counterparts. The cold-temperature method results in less stress on the metal and no warped or hardened parts.

At Laserfab, we offer waterjet cutting to our customers with a fair price, the highest-quality workmanship and quick delivery time. If you’re wondering why you should choose waterjet cutting, let us explain exactly what goes into it, how it works and what applications it has in today’s world. It truly is a technology without bounds — and with its ability to cut through nearly any substance, it still has plenty of untapped potential.

What Is Waterjet Cutting, and What Does It Entail?

Waterjet cutting is another means of cutting metal, plastic, stone and many other materials. Different than laser cutting and plasma cutting, waterjet cutting uses a high pressure stream of water and garnet to cut through material.

What is the waterjet cutting process? First, the workpiece is placed on the machine’s table, where a series of clamps hold it in place. Then, an operator communicates to a computer exactly what will be done. In a process that is entirely pre-programmed and guided by the computer, the waterjet cutting machine then begins to blast through the workpiece. The water that cuts through it gets recycled and reused, making the waterjet cutter much more environmentally friendly than if the water went to waste.

The thicker the workpiece, the longer a waterjet cutter will take to get through it. Waterjet cutting is an inherently slower process than laser cutting, and working with thicker materials lengthens this process considerably.

Though waterjet cutting is a slower process, waterjets can cut through more substances than not — here is a sampling of some of the typical work media:

  • D2 tool steel
  • Stainless steel
  • Steel
  • Aluminum
  • Bronze
  • Copper
  • Brass
  • Nylon
  • Polypropylene

As you can see, waterjet cutting can cut through a diverse set of material. Now let’s look at exactly how the apparatus works to get a better understanding of the technology.

How Does Waterjet Cutting Work?

The process starts with a high-pressure pump, which can be either a hydraulic intensifier pump or a direct drive pump. Industrial waterjet cutters use the hydraulic intensifier pump, in which a series of hydraulic rams increase pressure in the system to the desired level. The high-pressure water then passes through a series of valves and pressure gauges before moving through the intensifier, which ramps up the force even more using plungers. Hydraulic intensifier pumps have a higher upfront cost and are less efficient, with a maximum efficiency of around 65 percent. However, they cost less to maintain over time.

Direct drive pumps, on the other hand, use mechanical crankshafts to create high pressure in the system. Because there is less energy lost to friction, these pumps boast efficiencies close to 90 percent. Because direct drive pumps are more suited for lighter duty cutting, they cost less up front, but more to maintain in the long run. They are inherently simpler than hydraulic systems and have fewer moving parts.

At this point, the water is ready to move into the nozzle area.

The first gateway the water must pass through in the nozzle is the jewel orifice. This orifice is typically made of a precious gem such as sapphire, which is highly resistant to corrosion, heat and pressure. Additionally, the jewel is exceedingly low-friction — which is useful because a buildup of heat due to friction in this high-pressure environment could quickly lead to part failure. It would also result in a loss of energy and efficiency.

The jewel orifice focuses the stream of water downward through the nozzle. This point is where the abrasive inlet might allow grit to enter — in that case, the abrasive would be rapidly accelerated along with the stream of water and would aid in the cutting process. Pure water systems do not have an abrasive inlet. In any case, the water stream shoots downward and out the tip of a nozzle, where it begins the cutting process.

How High Is the Pressure?

One of the greatest debates in waterjet cutting is the optimal level of pressure in the water system. This debate generally falls into two schools of thought: the 60,000 psi team and the 90,000 psi team. Essentially, those who advocate high pressure note that the speed of cutting increases when pressure approaches 90,000 psi. In fact, the faster velocity of water does increase the speed of cutting by a factor of 1.5, and it has the added effect of requiring less abrasive.

On the other hand, the lower-pressure team argues high pressure decreases efficiency. They claim a waterjet cutting machine might achieve the same cutting capabilities running a direct drive pump at 60,000 psi as a hydraulic intensifier at 90,000 psi.

At Laserfab, we use the high-pressure system with garnet abrasive because it works more quickly, which results in a lower cost for the consumer. Laserfab uses Dynamic Waterjet cutting technology combined with the Lantek Expert software, which produces optimized results while still allowing faster cutting speeds.

The Benefits of Waterjet Cutting

Industry experts typically compare waterjet cutting to laser cutting and plasma cutting, both of which can achieve similar results. However, waterjet cutting offers some benefits that set it apart from its competitors:

  • It is a cold-cutting process. Because waterjet cutting does not produce the intense heat plasma and lasers do, it does not melt, harden or warp the edge of the material it is cutting. Waterjets result in a smooth, visibly undisturbed edge that is not disproportionately strained or affected by heat.
  • It can cut in all directions. The waterjet cutting nozzle is not limited to a two-dimensional set of axes. It can rotate and swivel to cut at all sorts of angles, thereby making it incredibly versatile.
  • It usually does not require starting holes. Many times, metals require starting holes for a jet to cut through them. Waterjet cutting typically does not, which results in less labor, less time and less cost to the customer.
  • It cuts through almost anything. As mentioned before, there is a very short list of materials waterjet cutting will not penetrate.
  • It can easily produce a finished product. Though this varies with the application, it is often the case that a waterjet cutting process will produce a finished product that does not require further work.
  • It is environmentally friendly. The water used in waterjet cutting gets recycled in a closed-loop system, and at high pressures, a smaller amount of abrasive is necessary, which results in less waste.
  • It does not produce much dust or dangerous gas. Water and abrasives blast through the material and carry the majority of the debris down into the drain, which reduces the amount of potentially breathable gas produced.
  • The machine programming is flexible. One of the greatest strongpoints of waterjet cutting is its ability to adapt to many different parameters and needs. It results not only in creative uses of the system, but also the ability to alter the process at any point as needs dictate.
  • The small kerf width means less waste. The wider the kerf width, the more waste material the cutter removes from the workpiece. With waterjet cutting, a kerf width of around 0.01″ means less waste and more recyclable scraps.
  • It is faster than traditional cutting methods. While waterjet cutting may be a bit slower than laser or plasma cutting, it is still much quicker than other cutting methods. Additionally, what it lacks in speed, it makes up in pinpoint accuracy and smooth edges.

Uses and Applications of Waterjet Cutting

Waterjet cutting creates intricate, precision designs without the application of heat. It is useful for many different industries and applications, including the following.

  • The aerospace industry: Waterjet cutting creates the bodies of military aircraft, which are generally made of titanium, as well as parts of their engines. Because many of these components are heat-resistant, waterjet cutting does not interfere with their intrinsic resistance. It is also useful for cutting aluminum components and for panels inside the cabins.
  • The automotive industry: This technology is perfect for cutting floor liners, dashboard and door panels, carpets and many other parts of the interiors of cars. Waterjet cutters also cut fiberglass components and insulation, as well as parts underneath the hood. Bumpers, trunk and truck bed liners, foam and plastic components are all mainstays of automotive waterjet cutting.
  • The electronic industry: Waterjet cutting is useful in cutting circuit boards, and can be used whether the circuit board is already populated or still empty. Additionally, the stream of water is useful for stripping the insulation off wires.
  • The food industry: Waterjets can cut frozen meat, whether it be fish, chicken nuggets, strips or any other type of meat. Waterjet cutting is also a sanitary and fast way to cut vegetables like celery, mushrooms, carrots and more. Food manufacturers may also cut snacks and cakes by waterjet.
  • Fiberglass: Fiberglass is used in many different applications, and waterjet cutting is useful for cutting most of them. Pink fiberglass insulation comes in cleanly cut sections, which waterjet cutters often score. Rigid foam board insulation also uses waterjet cutting to create its 4’x8′ panels. Boats are also made of fiberglass, and waterjet cutting is an efficient way to create the shapes, holes and precise edges needed for a proper fit. The same goes for personal watercraft like jet skis.
  • Slits: Slitting is a delicate procedure that requires the right kind of cut. Whether the slit needs to go in corrugated boxboard, food, paper materials, fiberglass or other products, waterjet cutting is perfect for creating narrow slits.
  • Gaskets: Gaskets play an important role in engines and other mechanical devices, and they often must stand up to pressure and heat while continuing to provide cushion and isolation. Waterjet cutting is used on gaskets for marine, automotive and aerospace applications. It can cut gaskets made of Teflon, fiberglass, metal, rubber, graphite and other materials.
  • Interior design: Whether cutting stone, tiles, shower screens, balusters, glass inlays or stained glass, waterjet cutting is a reliable way to cut materials used inside the home. It can also produce stepping stones and bench tops for use around houses.
