What is polyurethane down holder damper?

The down holder damper is made of polyester based PU which provides a new solution in pressing tools to replaces overloaded PU springs.

Sheet metal forming is widely used in the automobile die industry with quick cycling speeds. When opening the press after the pressing process, the holding screws and the actual tool are required to be protected. Due to the increasing return stroke speeds, the forces on the down holder dampers have increased significantly and the traditional springs cannot meet the needs.
