Progressive Die Presses
Trans-Matic’s progressive die stamping presses range in tonnage from 45-500 tons. While the majority of Trans-Matic’s parts are created with transfer presses, we use progressive die stamping to craft components with low diameter-to-length ratios.
Our progressive die stamping process utilizes state of the art press technology to maximize efficiency. Whether your part is produced with a transfer press or a progressive die press, we’ll ensure you receive the highest quality stamped parts.

How Progressive Die Stamping Works
In progressive die stamping, the press uses an automatic feeding system to push a strip of metal (as it unrolls from a coil) through all of the stations of a progressive stamping die.
Each station performs one or more operations until a finished part is made. The final station is a cutoff operation, which separates the finished part from the carrying web. The carrying web, along with metal that is punched away in previous operations, is treated as scrap.
The progressive stamping die is placed into a mechanical or servo driven stamping press. As the press cycles, the top die moves up, which allows the material to feed through the die. When the top die moves back down, the die closes and performs the stamping operation.
As the part advances to additional stations in the press, it is important that the strip aligns with the tooling within a few thousandths of an inch. Bullet shaped or conical “pilots” enter previously pierced round holes in the strip to assure this alignment.
One or more operations are performed at each station, until a finished part is made. The final station is a cutoff operation, which separates the finished part from the carrying web. The carrying web, along with metal that is punched away in previous operations, is treated as scrap. With each stroke/cycle of the press, one or more completed parts are cut off and removed from the die.
Progressive die presses come in many sizes from renowned press manufacturers such as Aida, Blow, Bruderer, Chin Fong, Danley, Komatsu, Minster, Schuler, Mueller Weingarten, Seyi, Stamtec, Sutherland, and Verson.
