Rubber Air Spring for Die Cushion 

A Rubber Air Spring for a Die Cushion is a pneumatic elastomer spring used in stamping and press machines to provide controlled counterforce during deep drawing, forming, and blank-holding operations. It is commonly used as a replacement for conventional coil springs, rubber pads, or hydraulic cushions because it provides a more uniform force throughout its stroke.

How it works

A rubber air spring consists of reinforced rubber bellows filled with compressed air. As the press operates, the air spring compresses and generates a nearly constant force over a wide range of travel, helping:

1.Control material flow during forming
2.Reduce wrinkling and tearing
3.Absorb shock loads
4.Improve part quality and tool life
