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
