Dampers for for pressing tools

The innovative down holder damper made of co-polyester elastomer results in a new solution as a damper in pressing tools and replaces overloaded PU springs. Sheet metal forming is increasingly taking place in the automobile and household appliance industry with faster cycling speeds. When opening the press after the pressing process, the holding screws and therefore the actual tool are substantially protected. Due to the increasing return stroke speeds, the forces on the down holder dampers have increased significantly and the PU springs cannot meet the new conditions. The PU springs often literally crumble after just a few cycles and leave holding screws, tools and down holders without protection. The holding screws tear-off and cause production failures and significant repair costs for the tools. As a result, the TUBUS-Special for holding screws from M10 to M30 were developed. The maximum energy absorption is between 5 Nm and 269 Nm.
