The Progressive Die Press



In progressive die stamping, the press uses an automatic feeding system to push a strip of metal through each stamping station. Each station performs one or more operations throughout the part-production process. Then the final station serves as a cutoff operation, which separates the finished part from the carrying web. The carrying web, along with metal punched away in previous operations, becomes scrap. With each stroke/cycle of the press, one or more completed parts get cut off and removed from the die.To get more news about progressive stamping, you can visit tenral.com official website.

To begin the process, we place the progressive stamping die 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, our quality assurance procedures ensure the strip aligns with the tooling within a few thousandths of an inch. Bullet shaped “pilots” enter previously pierced round holes in the strip to guarantee maintained alignment.

Progressive dies are one of the most popular and quickest methods for producing parts. Progressive dies utilize some of the original strip or coil, called a strip carrier, to tie parts together, which differs from the production method of line or transfer dies. Different carrier designs are needed to produce different types of parts.

Progressive dies can meet a wide range of production needs with their ability to produce as few as seven or eight parts per minute and up to 1,500 parts per minute. Unlike transfer or line dies, all stations are mounted on a single common die set. The timing and sequence of these stations are programmed to allow the piece part to be fed ahead with a constant progression or pitch. Multiple parts can be made with a single press stroke since many parts can be tied together.
