Types of Metal Fabrication

Determining the right metal fabrication for you hinges on several factors, including the purpose of the product, the geometry of the piece, and the materials used in its crafting. 

Standard metal fabrication projects include:

  • Welding
  • Casting
  • Folding
  • Cutting
  • Forging
  • Punching
  • Machining
  • Extrusion
  • Shearing 
  • Stamping 

The following paragraphs look at a few of these processes so you can get an idea of what is most suitable for your needs.

Welding 

Welding is when you join two or more pieces of metal together through a combination of pressure and heat. This is a popular method of metal fabrication because metal pieces can be of any size or shape. 

There are four main types of welding processes: 

  • MIG welding (Metal Inert Gas): This type of welding is popular in the automotive industry. It can provide a strong weld even for a very thin piece of metal. 
  • SMAW Welding (Shielded Metal Arc Welding) is popular because it requires the simplest equipment and is versatile. 
  • TIG Welding (Tungsten Inert Gas) is a popular choice for pipe welding. It’s suitable for thin materials and is popular in the aviation and aerospace industry. 
  • FCAW (Flux Cored Arc Welding) is the best choice when welding contaminated, rusty or dirty metals.

Casting

Casting is the process of molten metal poured into a die or mold and allowed to cool and harden into the desired shape.

This particular metal fabrication method is ideal for mass-produced parts as the molds are reusable for identical results.

The types of casting include:

  • Die Casting forces liquid metal into a die, and pressure keeps it in place until it hardens. 
  • Permanent Mold casting creates stronger castings than die castings by pouring liquid metal into a mold. The downside is that the finished products can prove challenging to remove. 
  • Semi-permanent mold casting makes a good alternative. These molds are more manageable and cost less to remove as they have expendable cores. 
  • Sand Casting is created by pressing a pattern into a fine mixture of sand. This makes a mold into which you pour liquid metal. This method is the most economical casting form, but it is generally slow.

Folding

The folding process involves manipulating metal to bend at an angle. The most common method uses a brake press which creates creases in the metal by pinching it. 

The metal is held between a die and punch and forced to crease by the punch pressure. Folding is also achievable by hammering the metal until it bends to the desired angle or using a folding machine.

This machine has a flat surface on which the material is placed, clamping bars to hold it in place, and a front panel that lifts upwards forces the material to bend. This process is usually used when shaping sheet metal. 

Cutting

Cutting is a popular form of metal fabrication for fashioning metal into smaller sections. Traditional methods involved sawing the metal, while modern techniques include waterjet cutting, laser cutting, and power scissors. 

Cutting tools range from manual power tools to CNC equipment (Computer Numerical Control). CNC equipment can control a range of complex machines such as lathes, grinders, and turning mills. All of which can shape, cut, and create different prototypes and parts. 

Die-cutting is another method. Two examples of die-cutting are rotary die-cutting, which uses a cylindrical die to cut material fed through a press, and flatbed die-cutting. This method is used on thicker metals and uses a die on a press to cut shapes by stamping the die down onto the metal. 

Forging 

Forging is one of the most old-fashioned metal fabrication methods used for centuries, so it’s definitely worth mentioning here. 

Forging requires a compressive force to shape the metal. Hot forging, where you heat the metal to 75 percent of its melting temperature, typically comes to mind with this process. However, cold forging is also possible, where the manufacturing process can occur at room temperature.

5 Types of Metal Fabrication

Did you know the metal fabrication equipment market will reach an impressive $92.84 billion by 2025? This growth is because of a rapidly increasing need for advanced infrastructure and growing industries – an industry in which you may already be a part.

How do you keep up with the demand for high-quality products? How do you stay on top of your competitors? First, you need to work with a manufacturer who is the best at what they do.

Keep reading to learn everything you need to know about the different types of metal fabrication and what Elemet Manufacturing can do for you.

Who Is Elemet Manufacturing?

Elemet Manufacturing exists because of the dual efforts of Precision Waterjet Concepts and Aitkin Iron Works. With the combined expertise of Aitkin’s over 87 years of farming, logging, and mining experience; and Precision Waterjet’s understanding of complex manufacturing work, there is no better company to serve your custom metal fabrication needs.

Machine shops come and go, but fabrication is eternal. Where there is a manufacturing need to fill, there is a metal manufacturing process to suit.

Breaking Down the Different Types of Metal Fabrication

It is critical to understand the foundations of any manufacturing process before you decide to work with it. As a company with expertise in the matter, however, we are here to advise you.

At its core, the metal fabrication process is all about turning raw materials into new, ready-to-assemble shapes. Custom metal fabrication procedures, for example, are used to create the panels that make up the frame of cars and other vehicles.

While this seems simple, the processes involved are rather complex and varied. Some methods are better suited to specific tasks, while others can accommodate a variety of processes.

Waterjet Cutting

A water jet cutter is a piece of industrial equipment that can cut a wide range of materials using an extremely high-pressure jet of water.

‘Abrasive jet’ refers to the use of a water-abrasive mixture used to cut hard materials like metal, stone, and glass. We use a pure waterjet for softer materials like wood and rubber.

If you’re looking for precision, the 5-axis waterjet cutting machine can tackle even the most complex of tasks. While a waterjet can cut almost any material, the time to cut a piece is longer than other processes.

Metal Stamping and Bending

Stamping is a cold-forming technique that transforms flat metal blanks into a variety of shapes. This method employs a tool and die that, when struck, changes the shape of the metal through sheer pressure.

Punching, bending, and embossing are all examples of stamping in the sheet metal production business. Metal bending or folding is a sophisticated production procedure that involves manipulating a metal surface to a specific angle.

The goal is predominantly to have the metal fold at a 90-degree angle. However, because of the complexity of the process, folding needs to be done in facilities that have specialized, high-tech equipment. Often, connecting two metal panels at specific angles may be more workable with a welding process.

With metal stamping comes a high level of automation, so it’s great for jobs that require quick and precise output. However, a disadvantage to note is that dies can be challenging to change if the design needs to change at any point in production.

Welding

Welding is one of the most common metal fabrication methods in the industry. It is basically the technique of connecting two separate metal components together. You can connect sheets, panels, bars, and any kind of shape using the welding method, as long as constructed out of metal.

You achieve this process through the application of heat along the edge where the two pieces connect. You can accomplish this with a variety of procedures and tools.

Welding is great because welded joints have a high strength load, and you can weld a variety of different materials. When done well, they provide a complete and rigid joint. However, once forged, that joint is permanent.

CNC Machining and Milling

The term CNC stands for computerized numerical control. CNC is a production method in which pre-programmed software controls other industrial tools and machinery to achieve the desired shape. From grinders to mills, a CNC method can successfully control a wide range of machinery.

CNC machining can perform three-dimensional cutting operations with just a few simple commands. Our 4-axis CNC machine is particularly good at producing high-quality products because it works on all four planes of a three-dimensional object.

CNC machining is not necessarily the right choice for small product quantities, as it takes some time to design and program. However, in terms of complexity, adaptability, and automation capacity, you can’t beat it.

Casting

Casting is one of the earliest forms of metal manufacturing and dates all the way back to 3,200 B.C.E. It involves pouring molten metal into a mold and leaving it to solidify again in place. Casting is the appropriate choice for a wide range of intricate shape-making needs as it is such a flexible way of fabricating metal.

Metals like steel, iron, gold, copper, silver, and magnesium are the most popular metals used for the casting process.

Casting is not suited to mass production and, compared to other methods, like forging, it has a low fatigue strength. It is, however, one of the cheapest methods of all the manufacturing types.

Waterjet Cutting

Plasma vs. Precision Waterjet Cutting

If you need to have raw materials cut, you have a few different options for cutting methods.

Two of the most popular methods for cutting raw materials are plasma cutting and precision waterjet cutting. Elemet Manufacturing offers the cutting services you need to accomplish any job.

Elemet Manufacturing is located in Aiken, Minnesota. Formed by combining the forces of Precision Waterjet Concepts and Aitken Iron Works, Elemet Manufacturing can meet all of your cutting and machining needs. 

Elemet offers CNC machining, CNC milling, turning, threading, 5-axis precision waterjet cutting, welding, painting, and other complementary services.

Elemet Manufacturing offers state-of-the-art precision waterjet cutting that can handle even the most challenging jobs. Elemet provides two options for precision waterjet cutting, CNC abrasive waterjet cutting, and pure waterjet non-metal cutting. 

CNC abrasive waterjet cutting is best for metals like stainless steel, carbon steel, aluminum, and titanium. Pure water non-metal waterjet cutting machines are best for non-metallic materials like plastic, foam, rubber, carpet, glass, marble, and stone.

What makes Elemet unique is its 5-axis precision waterjet cutting technology. Most waterjet cutters make flat cuts along three axes: X (left to right), Y (up and down), and Z (parallel). Elemet, on the other hand, can achieve precise, intricate 3D cuts by cutting along five axes.

In addition to the X, Y, and Z axes, Elemet precision waterjet cutting machines can also cut along the A-axis, which rotates around the X-axis, and the B axis, which rotates around the Y-axis.

Elemet’s 5-axis precision waterjet cutting machine can even cut stainless steel by combining high-velocity water with an abrasive material. 

Elemet’s state-of-the-art machines can cut metal at two to four times the speed of traditional machining. If you’re interested in cutting services from Elemet, complete an estimate form.

Depending on your job, either waterjet or plasma jet may be the best option for you. Read on to learn more about waterjet vs. plasma cutting to choose the best cutting method for you.

Precision Waterjet Cutting

precision waterjet cutting

With waterjet technology, a machine uses a mixture that usually includes water and some abrasive material. The machine forces this ultra high-pressure water mixture along a designated path, thus cutting the raw material.

To achieve this mixture, the abrasive material (very often garnet) travels through a line into the mixing component of the machine.

In the mixing component, the abrasive mixes with water. From there, the machine sprays out the mixture with ultra high pressure, exceeding 50,000 psi. 

This process creates a cutting stream that sprays out of the tip of a ceramic nozzle. The cutting machine moves this nozzle along a path designated by the machine’s software and at an appropriate cutting speed for the material.

Plasma Cutting

A plasma cutting machine

Rather than using water and abrasive materials, plasma cutters rely on gas (often nitrogen, argon, or oxygen) and electricity to achieve precise cuts.

Plasma cutting machines force gas through a small opening at extremely high pressures. Once forced through this opening, the gas meets with electricity that travels through the cutting nozzle. 

During this process, the gas is heated to such a high temperature that it becomes plasma. Given its high temperature, the gas can melt raw materials, blowing away excess materials and leaving a precise cut.

Comparing Waterjet to Plasma Cutting

Professionals in the cutting industry consider precision waterjet cutting to be more precise than plasma cutting—precision waterjet cutting results in higher cut quality across a variety of materials. 

Most waterjet cutters can cut at a precision of +/- .005 inches (although some are even more precise than this). Unlike some plasma cutters, the cutting speed can be adjusted on waterjet machines, leaving a smoothly finished surface that does not require secondary machining.

Plasma cutters can also create smooth finishes, although their precision of +/- .01-.03 inches is markedly less than waterjet cutters. 

The thicker the material, the less precise and clean the cut will be when you’re dealing with plasma cutting machines. The high-temperature plasma cannot always melt through thick materials without creating unwanted slag along the cut.

Another difference between waterjet and plasma cutting involves materials. Plasma cutters are limited to cutting metals, including steel, stainless, and aluminum. 

Plasma cutters are not recommended for cutting conductive metals because these materials do not cut well on the machine. Experts recommend plasma cutters cut through materials no greater than .5 inches thick.

Waterjet cutters, on the other hand, can cut through virtually any material. Precision waterjet cutting machines can handle hard materials, like steel, and can cut soft materials, like bread.

Because waterjet cutters do not rely on heat to achieve cuts, they can cut through materials of considerably more thickness than what plasma cutters can handle.

Cost

The determining factor between waterjet and plasma cutting is often the cost. For thinner, metallic materials, plasma cutting is often the quicker and cheaper option. 

However, when cutting thick and/or non-metallic materials, precision waterjet cutting is better and less expensive. Furthermore, precision waterjet cutting can eliminate the need for secondary machining, thus saving further on costs. 

Wrap-Up

While there are many options for machine cutting, depending on the material and thickness of your job, the leading two technologies are precision waterjet cutting and plasma cutting. 

Precision waterjet cutting achieves precise, finished cuts by combining water with abrasive material and shooting a cutting nozzle at incredibly high velocity.

On the other hand, a plasma cutter heats gases to very high temperatures and achieves cuts by melting the raw material.

When it comes to cutting services, Elemet Manufacturing cannot be beaten. Elemet offers state-of-the-art, advanced cutting technologies to meet all of your needs. 

With its innovative, 5-axis precision waterjet cutting system, Elemet can tackle jobs from dense stainless steel to pliable plastic and rubber. If plasma is more appropriate for your cutting needs, Elemet also offers plasma jet cutting services.

5 Tips on How to Choose a Machine Shop

Good relationships are vital to the heart of all business. If you require a custom piece of machinery, you need to trust the shop that is in charge of manufacturing. Choosing a machine shop that is right for you can be the start of a valuable business relationship. 

With options available, it can be overwhelming to find a shop to meet your needs. The key to choosing the shop that’s right for you is setting your expectations first. 

In this blog post, you will find tips on choosing a machine shop that will put you first. Not only that, but you will have the machinery and skills needed to give you the product you deserve. 

Elemet Manufacturing specializes in metal turning services throughout the United States. Contact us today!

Choose a Machine Shop 

It is worth reiterating that any new business relationship should be researched and cautiously entered. Here are some of our tips to get the very best work available when looking for a reliable machine shop.

1. Reputation 

Good old-fashioned online reviews are an excellent way to begin your dive into a shop’s reputation. Not just paying attention to the rating given, but the comments left can also go a long way into giving you a peek into how they treat customers. 

It would help if you also remembered that one bad review out of several does not mean that you’ve found a lousy shop. You may want to research what clients they have had and possibly how long that relationship lasted. 

Longer relationships with customers can be a display of a great working relationship.

Word of mouth is also valuable. If you know someone that has used the shop you’re considering, ask them about their experience. You may also get to see firsthand the work completed. 

A high customer turnover rate or a lack of reviews can be a sign to proceed with caution. In most circumstances, clients will often want to praise good work. It’s a nod to the service received and a connection from one good business to another.

2. Are their cards on the table?

When you have a meeting or consultation with the machine shop of your choice, you should be on the lookout for transparency. 

A good shop should share the following without hesitation: 

  • The shop’s failure rate and how they plan to fix errors. All shops have this rate, and owners should not hide it. 
  • Certifications: Certain skillsets and machine operations require certificates. Those should be available upon request. 
  • Have they dealt with a variance of projects and quantities in their shop?
  • They should have a plan on how to handle modifications if they are requested. 

No shop is perfect, and they should tell you how they deal with setbacks with production. Also, if they can do your job from start to finish. 

3. They have the right tools for your job.

Whatever your needs, the shop taking on your project should be able to do the job from start to finish. Before your initial meeting, consider researching the necessary machines for your job. 

Only doing part of the job and then going to another shop to finish can result in work that is not consistent and can waste time. It can also unknowingly increase your budget and draw out your timeline. Time is money, and needing both can throw a wrench into your plans. 

Upon your first meeting with the potential machine shop, they should tell you if your entire project can be completed in-house. 

4. Investing in the future and education are essential.

Shops that invest in their future plan on sticking around, often shown through certifications and having proper machinery. Having the correct credentials for machinists and up-to-date machinery shows they believe in their product.

Ask your contact what machines they have on the floor and if those same tools are used on the production and prototype runs. If they are not, then ask why and how does that change the product?

Certifications are also a good indicator of the priorities and quality of a shop. The certifications not only ensure that machinists know what they’re doing but that they will invest in their team.

5. Care and communication

No matter what the project or business, communication is vital. Going a step further, you should also feel that they care. The person set as your contact should be able to explain what is going on with your project at any time. 

If an issue arises, your representative should contact you promptly with how they will solve that issue. Online reviews and testimonials should speak to how well or poorly a shop has matters handled. 

The representative handling your project should also be well versed in what their shop offers. For example, Elemet offers laser and water jet cutting. Our representatives can explain the pros and cons of each as well as the differences

It is their job to guide you through the process of your project and provide transparency. In an ideal setting, this would include having one contact who knows your project. Having too many hands in the project can lead to confusion.

What Is CNC Machining?

A (Very) Brief History

John T. Parsons is considered the pioneer of “numerical controls,” the precursor to today’s CNC machines. Parsons needed to manufacture complex helicopter blades and quickly realized that the future of manufacturing was connecting devices to computers. Parsons was dubbed “The Father of the Second Industrial Revolution” to work on these controls.

CNC Machining Today

Today, we find CNC-manufactured parts in practically every industry.

The term “CNC Machining” is commonly used in industrial and manufacturing applications, but precisely what is a CNC machine?

CNC machining systems use computers to run programs that control how they shape or finish the desired parts.

These CNC programs can control everything from the machine’s motions to spindle speed, turning coolant on or off, and much more. Manufacturers can use this technology to perform a range of complex processes, including grinding, routing, milling, punching, turning, and lathing. With CNC machining, machine shops can accomplish complex three-dimensional cutting tasks with a single set of prompts.

Most people choose machined parts when manufacturing requires high precision, high quality, or when the materials are particularly tough and hard to work. CNC machining services revolutionized the manufacturing industry in the 1960s and is the most used method today.

CNC machining is suitable for various industries, including aerospace, agriculture, and construction. It can produce multiple products, such as airplane engines, automobile frames, garden tools, hand tools, and surgical equipment.

The process encompasses several different computer-controlled machining operations — including mechanical, chemical, electrical, and thermal processes, removing the necessary material from the workpiece to produce a custom-designed part or product.

What Are The Different Types Of CNC Machines Used In A Machining Shop?

The earliest numerical control machines date back to the 1940s when motors controlled the manufacturing tools’ movement. As these technologies advanced, engineers enhanced these mechanisms. First with analog computers, and then ultimately with digital computers, leading to today’s CNC machining.

The vast majority of today’s CNC machining arsenals are entirely electronic. Some of the most common CNC-operated processes include ultrasonic welding, hole-punching, and laser cutting.

The most frequently used machines in today’s CNC machining systems include the following:

CNC Mills

Milling is a process that employs rotating multipoint cutting tools to remove material from a workpiece. The CNC milling machine typically feeds the workpiece against the cutting tool in the same direction as the cutting tool’s rotation.

Basic mills consist of a three-axis (X, Y, and Z) system. Most newer mills are more advanced and can accommodate three additional axes. Some of the more common CNC-operated capabilities include hole-punching, laser cutting, and ultrasonic welding.

CNC Lathes

In lathe machines, the workpieces are cut in a circular direction. With CNC technology, cuts are made with precision and high velocity.

CNC lathes produce intricate designs that wouldn’t be possible on manually run versions of the machine. The control functions of CNC mills and CNC lathes are similar. However, most CNC lathes consist of only two axes — X and Z.

Plasma Cutters

In a plasma cutter, the material is cut with a plasma torch. This process is generally applied on metal materials but can also be employed on other substrates. The plasma is created through compressed-air gas and electrical arcs to cut metal, producing the necessary speed and heat.

Waterjet Cutters

In CNC machining, waterjets are machining tools that cut hard materials, such as granite and metal. These cuts can happen with high-pressure water applications or, in some cases, the water is mixed with sand or some other potent abrasive substance. This process shapes many factory machine parts.

Waterjets are a cooler-temperature alternative for materials that cannot bear the heat-intensive processes of other CNC machines. Waterjets are used in various sectors, such as the aerospace and mining industries, where the process is powerful enough for carving and cutting.

Waterjets are also used for applications that require intricate cuts in material.

CNC Drills

Drilling is a machining process that employs multipoint drill bits to produce cylindrical holes in the workpiece. The CNC drilling machine feeds the rotating drill bit perpendicular to the workpiece’s surface.

CNC Turning Machines

Turning is a machining process that employs cutting tools to remove material from a rotating workpiece. The CNC machine – typically a lathe or turning machine – feeds the cutting tool linearly along the rotating workpiece’s surface.

It removes the material around the circumference until the desired diameter is achieved. Turning produces cylindrical parts with external and internal features, such as slots, tapers, and threads.

How Do CNC Machines Make Parts?

cnc-machining-services-03

CNC machine systems make it possible to program the machining tools’ speed and position and run them via software in repetitive, predictable cycles. This can all happen with little to no involvement from the machine’s human technicians.

Best of all, CNC machining services are by no means static since newer prompts can be added to pre-existing programs through revised code.

A very simplified peek into the process looks like this:

#1 – Design The Ideal Part

Designers use CAD software to design a 2-D or 3-D model of the part you need. CAD stands for “Computer Aided Drafting.” Therefore, CAD software is like drawing software that lets you precisely specify the dimensions for each part you need.

The optimal material for a CNC manufacturing application is mainly dependent on the particular application and its specifications. Most materials can be used, provided that they can withstand the machining process. This is demonstrated with sufficient hardness, tensile strength, shear strength, and chemical and temperature resistance.

The workpiece’s physical properties determine the cutting feed rate, depth of cut, and optimal cutting speed.

  • Cutting speed refers to how fast the machine’s tool cuts into or removes material from the workpiece, measured in “surface feet per minute.”
  • The feed rate calculates how quickly the workpiece feeds towards the machine tool in inches per minute.
  • Cut depth is how deep the tool cuts into the piece.

Typically, each workpiece will first undergo an initial manufacturing phase. It is measured to the approximate, custom-designed shape and dimensions. The workpiece undertakes a finishing step in which it experiences slower feed rates and shallower cut depths to achieve its more precise and accurate specifications.

#2 – CNC Programming

Engineers then use CAM software to convert the CAD model into a “g-code.” G-code is the language used to program the CAD model design into a CNC machining system.

#3 – Machine Setup

In this third step, the machine sets with work-holding, proper tooling, and the g-code program and tool data; loaded to prepare the machine to manufacture the part.

As part of this setup, the operator will also need to tell the machine where “Part Zero” is. Part Zero refers to the axis position that corresponds to 0, 0, 0 in the part’s CAD model.

After the program is inputted and the material is chosen, the operator gives it a “trial run” (or creates a prototype) to ensure no mistakes are present in the coding.

#4 – Machining The Parts

With the programming done and the machine set up, it’s time to manufacture the parts.

Advantages Of CNC Machining Services

As with the birth of any new technology, we must anticipate shifts and adjust to meet new challenges. This has never been more true in the manufacturing industry, as manufacturing and automation advancement and 3-D printing continue to progress.

Increased Productivity & Efficiency With Continual Use

Unlike manual labor, CNC machinery (of course, barring any malfunction or maintenance issue) can work continuously over an extended period without a break. This dramatically increases productivity and efficiency.

Consistency, Precision, & Redundancy

Through computer software, the design of any given product only needs to be fully programmed once. The manufacturing machine can then perfectly replicate that design for any order quantity. Adjustments made with programming require little to no effort to perfect any part.

Fewer Personnel

Because computer software controls CNC machining services, fewer technicians are needed for operation and oversight, cutting overall expenses.

Flexibility

The software can be reprogrammed quickly and efficiently to produce many parts, allowing operations to keep up with shifting customer needs and demands.

Capability

CNC technology uses computer precision to go beyond the limitations of manual drafting and crafting capabilities. More complex and intricate operations are also possible with CNC machining.

Why Work With A CNC Machining Shop?

Extreme precision demands CNC machining.

There’s no easy way to describe the benefits of high-quality, precision machining and its importance in today’s manufacturing economy.

While conventional machining methods are acceptable for some industries, other industries require tolerances of +/- .001″ or tighter. Often, thousands or tens of thousands of identical parts are needed for a single order. This need is close to impossible without CNC’s repeatability.

Any industry that relies on precisely-machined parts uses CNC machining services to create custom machined parts from raw materials, fabrications, or castings into individual components.
