This innovative TUBUS damper, crafted from polyester elastomer material, offers a groundbreaking solution for cushioning devices in stamping dies, serving as a replacement for overloaded polyurethane (PU) springs.
As cycle speeds in sheet metal forming processes for the automotive and home appliance industries continue to rise, clamping screws and core mold components require adequate protection when the press opens after stamping. Due to the continuous increase in return speeds, the impact forces borne by lower pressure plate dampers have significantly intensified, rendering traditional PU springs inadequate for these new operating conditions.
Traditional PU springs often fracture after just a few cycles, leaving clamping screws, molds, and lower pressure plates unprotected. The resulting breakage of clamping screws not only halts production but also incurs substantial mold repair costs. 
Compact yet highly efficient, these versatile custom components play a crucial role in sheet metal forming processes across the automotive and mold industries, delivering extended service life and exceptional energy absorption performance.
