PROGRESSIVE DIE STAMPING: COMPLETE TUTORIAL

When it comes to businesses, speed is a term that is not unheard of. Speed in the industry means that the products will be manufacture and deliver on time, which benefits the clients’ business goals. The same is true in stamp metal stamping, where there is a constant requirement for high manufacturing speed. Progressive die-stampe metal stamping parts differ from regular metal stamping parts due to their high speed of operation. Progressive metal stamping is used extensively in industries such as aerospace, automobile, defense, industrial engineering, and electrical and electronics.

What is Progressive die stamping?

Progressive die stamping is ideal for producing large quantities of parts with tight tolerances. This method involves feeding a coil of metal through a stamping press, which simultaneously punches, bends, and shapes the metal sheet into desired metal part.

The workpiece is attached to the base strip from start to finish—the final step is to separate the individual finished parts from the base metal strip.

The following metals are frequently used in progressive die stamping

  • Brass
  • Steel
  • Stainless steel
  • Aluminum
  • Copper

Here, there are multiple workstations, where different metal stamping operations take place. The part is moved from station to station on a stock strip, and the finished product is removed at the end.

Various Metal formation techniques

The progressive die stamping method frequently incorporates various metal modification techniques, such as:precision die & stamping

Bending:

Bending is the general term for forming metal into desired shapes such as L, U, or V-shaped profiles.

Punching:

Punching uses a die to cut the material into specific shapes. As the punch enters the die, scrap material is removed, effectively leaving a hole in the workpiece.

Coining:

Squeezing the workpiece under extreme pressure creates a pattern, which reduces the thickness of the metal.

Flanging:

The process of introducing a flare or flange onto a metal workpiece using dies, presses, or specialized flanging machinery is flanging.

Embossing:

A shallow depression is press into the material.

All of these alterations are accompanied by an automatic feeding system. This feeding system draws a strip of metal from a coil, allowing each station to complete its assigned task, ultimately leading to a finish part. The material from which the part is eventually separate is known as the carrying web, and it is relegate to a scrap bin to be recycle for future use once the cutting is complete.

Because work is done at each station during the progressive die stamping process, a strip must be advance with precision so that the metal aligns within a few thousandths of an inch as each movement occurs.

Progressive die stamping versus Transfer die stamping

The steps and processes involved in progressive die stamping are similar to transfer die stamping. The difference lies in how the metal sheet moves throughout the process. In Transfer stamping of the metal, the sheet is lift and place at different workstations. In the progressive stamping process, the work metal moves smoothly without any lifts throughout the metal stamping process. 

Therefore, progressive die stamping is a better choice to manufacture small and medium-sized metal stamping parts. Here is a small comparison between the process to understand why:

In Progressive Die Stamping:

  • Metal is fed into a machine where a series of stamping stations work in tandem.
  • The process allows for the simultaneous forming and cutting of multiple parts, saving both money and time.
  • It is ideal for mass-producing small parts in a short period.
  • Depending on the quantity produced, you may be able to save money.
  • It also allows you to keep close tolerances.

In Transfer Die Stamping:

  • The part is move from station to station using a mechanical transport system.
  • Also, It can be a single die or several dies lined up in a row.
  • It is more cost-effective than progressive die stamping.
  • It incorporates cut-outs, pierced holes, ribs, knurls, or threading directly into the process.
  • Large parts that can transfer between multiple presses are well suite for this machine.

In a nutshell

This is a high-volume, high-performance metal stamping process that employs progressive dies, which perform multiple operations in one die, often in a single press pass, thereby removing the need for additional secondary operations while meeting critical dimensions
