An Ultimate Guide To High Speed Stamping

Although achieving high production needs and quality is always a challenge in high speed stamping, this guide will make everything easier for you. It explores, and recommends best practices for high speed metal stamping – you will save on fabrication costs, and adopt the best sheet metal stamping machine and techniques.

What Is High Speed Stamping?

High speed sheet metal stamping is a process that uses controlled force to transform metal into useful shapes at a faster rate. The processes use presses with punches and die to apply the force.

Although there is no fixed metal stamping production rate, 1,000 to 1,600 strokes/minute is a high production rate.

However, the classification of high-speed stamping may depend on the industry.

Benefits Of High Speed Metal Stamping

There are many ways you can benefit from high speed metal stamping. These include:

  1. Reduce the cost of production – by adopting mass production, you can easily reduce the cost per part. However, this will also go hand in hand with the MOQ.
  2. Guarantee fast turnaround – with a production of 1,500 strokes/minute you can produce hundreds of metal stamped parts for any market needs.
  3. Ability to produce parts in bulk – you can produce many parts within a short period. You can easily meet customer demands with this high-production capability.

Uses Of High Speed Metal Stamping

Many industries require thousands of parts such as:

  • Aerospace
  • Automotive
  • Medical
  • Oil and gas
  • Mining
  • Home appliance
  • Electronics
  • Military

High-volume stamping plays an integral role in many industries. Manufacturers can design and assemble different fabricated metal parts faster to meet the increasing market demands.

You can make cans, cases, chains, eyelets, cups, brackets, enclosures, rings, know, and plates, just to mention a few.

Choosing Machine For High Speed Metal Stamping

Choosing a suitable sheet metal stamping for high production is a challenge for many companies.

For instance, your high volume stamping machine should meet the following criteria:

  1. The efficiency of the stamping machine
  2. Safety of stamping machine
  3. Accuracy and consistency of the stamping equipment
  4. Production capacity of the stamping machines – it should guarantee at least 1400strokes/per minute
  5. Punching force which may vary from 300 to 4500 kN
  6. Machine’s ability to handle vibrations due to high production speed
  7. Robust construction frame to handle vibrations
  8. Sheet metal stamping technology – there are many stamping techniques such as progressive die stamping, transfer die stamping, fine blanking, and four-slide stamping. Of course, there are other categories.
  9. Maintenance and service requirements
  10. Control mechanism

If this is a priority in your manufacturing setup, then fine blanking is a perfect option for you. You can achieve this using either a hydraulic press or a mechanical press.

Still, will you achieve the number of strokes you need?

Unless you got for automated models, you will not meet the high production capacity in high-speed metal stamping.

Additionally, fine blanking machines operate at high pressure. Therefore, the high-speed stamping press tools must withstand high pressure.

Mechanical Servo Press Vs. Hydraulic Press

Mechanical servo is a popular high-speed stamping press. It is perfect for complicated stamping.

Additionally, the mechanical servo press is faster than a hydraulic press.

Most sheet metal fabrication companies are adopting mechanical servo technology for precision high speed stamping processes. Of course, this is an addition to adopting CNC presses.

In short, you should focus on the production speed, which should be 1,000 to 1,600 strokes/minute or more. This should be alongside technology and stamping capability.

Choosing Material For High Speed Metal Stamping

Well, metal stamping is a versatile sheet metal fabrication process. You can fabricate all metals with this technology.

As a general rule, discuss the performance requirements of the parts you want to make. The metal fabrication company will advise you according.

At KDMFAB, we will help you choose the best materials for high speed sheet metal stamping.

Some of the most common materials for high-speed stamping include:

  • Copper and alloys
  • Aluminum and alloys
  • Stainless steel
  • Galvanized steel
  • Titanium
  • Bronze
  • Brass

Step-by-step High-Speed Sheet Metal Stamping Process

High sped stamping process involves several steps and operations. Some of the main steps include:

Step 1: Design Sheet Metal Parts

You will use suitable software to design suitable sheet metal parts and components. The sheet metal fabrication company will use the technical drawing for the entire fabrication process.

Step 2: Know the Type Of Sheet Metal Stamping Operation To Adopt

It is important to note that sheet metal stamping involves a range of operations and techniques. Some of these operations may include punching, coining, embossing, or blanking.

Additionally, high-volume stamping may involve either one or more operations. For instance, you may use punching and blanking in one component.

Again, it can be either progressive or transfer die stamping. Whichever the case, your high-speed stamping service provider will offer the best advice.

Step 3: Design Tooling For High-Speed Stamping

The type of tooling will depend on the specific parts you want to produce. Of course, you will work closely with the service provided during the highs speed die design.

This will also include other high-speed stamping press tools such as punches.

Note: It is better to work with a service provider with an in-house tooling development capability. With this, you can easily customize fabricated sheet metal parts.

Step 4: Choose a Suitable Machine For High Volume Sheet Metal Stamping

Here, the speed of the machine is critical. You must choose a machine that guarantees high production.

For instance, 1000 strokes per minute are fair enough.

Step 5: Stamp Sheet Metal Parts Prototype

Before mass sheet metal stamping, you should make a prototype. You will examine the quality of the prototype to ensure it meets quality requirements.

Step 6: Begin Mass Sheet Metal Stamping

Once you approve the prototype, start the mass production process.

Step 7: Apply Surface Finish On Stamped Sheet Metal Part & Check Quality

Depending on the final type of sheet metal component you want, you can paint, galvanize, powder coat, or polish the surface.

Lastly, you will check the quality and package the stamped parts for shipping.

Although high seed stamping is best for mass production, you may deal with:

  • Faster tooling wear such as chipping
  • Scrap metal if you didn’t verify and test the prototype
  • Small punches tend to overheat due to the inability to dissipate heat

Conclusion

As you can see high-speed stamping depends on the speed of the stamping machine. But even before that, you should ensure you have a good part design, tooling, and quality inspection.

Verifying prototypes at early stages will eliminate the possibility of waste.

Lastly, the stamping technique is only suitable for mass production.
