Polyurethane Car Die Spring PEPSEN Polyurethane Car Die Springs are designed primarily for applications where corrosion, vibration, and magnetism prevent the use of conventional steel springs. Also, Polyurethane Car Die Springs have proven to be the safest, most efficient and reliable compression springs for punching, stamping and drawing dies. As compared to conventional springs, the advantages of the Polyurethane Car Die Spring include the following: High load-carrying capability High dielectric strength and non-magnetic Protection against marring/galling Longer life Abrasion resistance Oil and solvent resistance Low noise Vibration damping and shock absorbance 100% load-bearing surface Bondable to mating parts Standards we can meet include :MISUMI, TOYOTO,RENAULT,VOLKSWAGEN,SANKYO,HONDA
