Metal stamping is a process used across a variety of industries in the US and Canada. From the automotive and aerospace industries to medical spaces, the process is integral to the creation of metal components.

Metal stamping allows for the production of goods in large quantities and is a quick process, but, it can be costly.

In this article, we&#;re going to go over the basics of metal stamping, the types of metal stamping services you may come across, and ways that you can reduce the cost of metal stamping for your business. Keep reading to learn more.

What is CNC Metal Stamping?

CNC Metal stamping is a manufacturing process used to create metal components. It is the conversion of flat metal sheets into a range of shapes. CNC stamping techniques include punching, blanking, embossing, bending, flanging, and coining. Many are carried out by a metal cold stamping machine and the results are flawless.

As a manufacturing process, metal stamping is generally low cost and high speed. The process allows for a high volume of production and is an easy way to create lots of identical metal components. It can be used for both short and long production runs.

The Basics Of Metal Stamping

Most metal stamping companies follow the same processes. A high-quality sheet of flat metal will be placed in a stamping press (the sheet metal may be in coil or blank form).

In the CNC machine, a tool and die surface form the metal into the shape you desire. Depending on what it is you need from the process, there are many types of metal stamping.

Types Of Metal Stamping

There are three common types of metal stamping: progressive die stamping, fourslide stamping, and deep draw stamping. Keep reading to learn more about these common types of metal stamping:

Progressive Die Stamping

Progressive die stamping is a form of metal stamping that uses several different stations. Each station has its own function. As the strip metal moves through the progressive stamping press, it unrolls from a coil and into the die press.

Once in the die press, each station of the tool performs its own unique cut, punch, or bend. The idea behind progressive die metal stamping is that each different cut, punch, or bend builds on the previous station&#;s efforts.

Fourslide Stamping

Fourslide stamping is also referred to as multi-side stamping. It involves four different slides and a horizontal alignment. The process works as four tools work simultaneously on the piece. It allows for multiple intricate cuts at a time to develop intricate components.

As the sheet metal is fed into the fourslide metal stamping machine, it is bent by each tool attached to the machine.

Deep Draw Stamping

Deep draw metal stamping forms sheet metal into a shape by pulling it into the die through a punch. The term &#;deep drawing&#; comes from a step in the process when the depth of the drawn part is larger than its diameter.

This type of metal stamping is used for creating components with several different diameters. It is much more cost-effective than turning processes. It is generally used to create components for the automotive and aerospace industries. It may also be used to create cooking utensils and other cookware.

Benefits and Drawbacks of Metal Stamping

As with any manufacturing process, metal stamping comes with advantages and disadvantages. The advantages of metal stamping are as follows:

Accuracy

The kinds of components made using metal stamping need to be as accurate as possible. This is for the safety and proper functioning of the parts made.

Metal stamping is highly automated, meaning that parts are generated with an incredible level of accuracy. The process uses stamping simulation technology, which marries technology with the stamping process. This process helps to root out flaws before the metal even enters the machine.

It&#;s Cost-Effective

Other methods of metal component creation have difficulty with smaller and more complex parts. They tend to be more expensive to make, but metal stamping has solved this problem. Small intricate parts can be made easily with the metal stamping process.

Metal stamping, as we have mentioned, is a highly automated process. This means that once the dies are set, there isn&#;t much left to do. Consequently, fewer engineers are needed, and labour costs are reduced.

This also has a knock-on effect on the price of these components, which can be much lower due to the relative cheapness of the manufacturing process.

Speed

Metal stamping is a relatively quick process, which means manufacturers get a much faster return on investment. Many metal stamping companies have equipment that works at thousands of strokes a minute, making this a high-volume, high-speed process for component production.

Speed, when combined with accuracy, makes for an excellent method of manufacturing and means that companies can bring out new products and technologies much faster.

Flexibility

One of the most incredible parts of metal stamping is the ability to create almost any kind of piece/shape imaginable. From minuscule component parts to highly complex shapes, the metal stamping process can produce it.

Disadvantages Of Metal Stamping

Although there are only a few, metal stamping does have some disadvantages. These include the high cost of presses, the acquisition of dies, and the production of custom metal stamping dies. It is also difficult to change the die if the design needs to be changed during production.

Ways To Reduce Sheet Metal Stamping Costs

While it is considered a cost-effective solution due to its speed, automation, and high-volume ability, metal stamping services can get costly quite quickly. Below, we have summarized a few of the ways you can keep the costs down on metal stamping:

Use softer raw materials - Harder materials are more difficult to work with and will slow the process down.
Stick to what you need - When it comes to materials, ensure that you&#;re using the metal you need and not the most luxurious metal out there. Using luxury metals when they are unnecessary will just increase the cost.
Optimize the process - Though it is usually cheaper if the part you&#;re making is touched less, make sure that this is the optimal method of production first.
Take &#;downstream&#; costs into account - This means that while saving on a raw material can be good in the short term, it may impact the overall quality of your part down the line.
Manufacture higher volumes - The more you make at once, the cheaper the entire process will be.

Laser Cutting Vs Metal Stamping: Which is Better?

There are many metal forming tools that the team at Marlin Steel uses to create custom sheet metal forms. Two of the most frequently-used types of metal forming machines on the Marlin production floor are laser cutting machines and metal stamping and press machines.

Every day, Marlin&#;s employees use one machine or the other to create custom metal forms for clients the world over. However, many of our clients ask us: &#;Which is better, laser cutting or metal stamping?&#; The answer depends on what the client needs.

To help you assess whether you should use laser-cut parts or ones shaped using metal stamping, here&#;s a quick laser cutting vs metal stamping comparison. In this comparison, you&#;ll find some of the pros and cons of each process.

The Advantages of Laser Cutting

Laser cutting machines are incredibly powerful tools for quickly cutting holes into sheet metal plates. Some of the key advantages of laser cutting machines are:

Stress-Free Cutting. Unlike a stamping machine or press brake, a laser cutting machine does not rely on mechanical force to penetrate metal. This eliminates many of the microscopic fractures and stress marks that might weaken a piece of sheet metal that was bent mechanically.
Extremely Close Cutting. When making custom metal shapes from sheet metal cutouts, the fact that laser cutting is stress-free allows for metal shapes to be cut extremely close together. This allows for extreme material efficiency when creating metal cutouts&#;allowing more metal shapes to be created from a single metal sheet.
Smooth Edges for Cuts. Another benefit of using lasers to cut sheet metal forms is that the laser leaves behind a smooth, shiny surface. This helps to reduce the risk of sharps or burrs being left behind on a laser-cut object.
Reduced Tooling Wear. Because a laser cutting machine doesn&#;t need to make physical contact with the workpiece, there is far less wear and tear on the laser cutter than there would be on a bending machine or press brake. This helps to extend the useful life of the laser cutting machine while reducing maintenance costs (though the laser diode will still need to be serviced or replaced eventually).
Less Need for Secondary Operations. Because the laser cutter leaves a smooth cutting edge, there&#;s less need for secondary operations to remove sharps and burrs. This helps to increase overall manufacturing speed so more parts can be manufactured in a day.

What Disadvantages Does Laser Cutting Have?

So, what are some of the disadvantages of laser cutting? Some of the key things to keep in mind with laser cutting are:

Laser Cutting May Alter Steel Properties. Some types of steel alloys may change their chemical properties after being exposed to extreme temperatures&#;such the temperatures involved in the laser cutting process. This can impact the performance of the workpiece after the fact. So, laser cutting isn&#;t always recommended for use on metal alloys that experience such changes.
Laser Cutting Machines Have Cutting Depth Limitations. There is an upper limit to how thick a piece of metal can be before the laser cutter will not be able to make a clean cut. This may vary from one workpiece to another depending on the type of metal it&#;s made out of. If the metal is too thick for the laser cutter, there may be some spalling and distortion in the cut.
Laser Cutting Machines Cannot Make Bends. Some sheet metal forms require the metal to be both cut and bent. Lasers, unfortunately, cannot bend metal forms. For this task, a metal stamping or bending machine is required.

Advantages of Metal Stamping Machines and Press Brakes

Metal stamping machines and press brakes are incredibly useful for custom metal forming. But, what makes these machines preferable to laser cutting machines? Here are a few of the advantages of using metal stamping and press brake machines:

More Than Just Cutting. The biggest advantage of metal stamping and press brake machinery is that these machines can do more than just cut holes in metal. A metal stamping machine, for example, can flatten, swage, or coin metal into a specific shape to meet a need. Meanwhile, press brakes can bend sheet metal or steel wire forms at specific angles to create complicated shapes for specific applications.
Shaping Thicker Metal Plates. Press brakes and metal stamping machines are limited primarily by the amount of force they can apply to a workpiece and the condition of the die. This allows high-tonnage presses to shape and cut metal forms that are thicker than what some laser cutting machines can manage.
Shaping a Wider Variety of Metal Alloys. High temperature-resistant metal alloys can be difficult to cut with a laser because their melting point is so high. Press brakes and metal stamping machines can shape and cut these metals more easily than laser cutters. This makes press brakes and stamping machines preferable for some metal forming applications.

What Are the Disadvantages of Metal Stamping and Bending?

What are some of the disadvantages of using mechanical force for metal forming? Two of the cons of using metal stamping machines are:

High Tooling Maintenance. To keep metal stamping and press brake machines working in top condition, they require frequent maintenance. Tools and dies can wear out quickly, especially when being constantly used to shape hard metal alloys such as annealed and stress-relieved grade 430 stainless steel. This means more time and money spent on mechanical maintenance.
Some Bends Create Structural Weaknesses. If not handled correctly, a metal bend or cut can create structural weaknesses. For example, if a bend is too deep for the metal&#;s internal radii limitations, or if there is some improper motion during a cut, it could make the metal brittle and easy to break.

So, which process is better for your manufacturing process? That&#;s an answer that depends on the application and materials involved. If you need help creating the perfect custom metal form for your needs, contact the Marlin Steel team today!
