Progressive Die Stamping

Trans-Matic’s progressive die presses range from 45-300 tons. While the majority of Trans-Matic’s parts are created with transfer presses, we use progressive die presses to craft particularly complicated components and parts with low diameter to length ratios. Trans-Matic machines utilize 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 at the lowest cost.

About Progressive Die Stamping

Progressive die presses use 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 stamping press. As the press cycles, the top die moves up with the platen, which allows the material to feed through the die. When the press platen moves down, the die closes and performs the stamping operation. With each stroke/cycle of the press, one or more completed parts are cut off and removed from the die.

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 since the feeding mechanism usually cannot provide the necessary precision in feed length.

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.
