WPC processing

In the drive system components, fatigue strength has significantly improved! This greatly reduces troubles such as shaft breakage.

"WPC processing" is a technology that modifies metal surfaces by mixing fine particles with a compressible gas and colliding them at high speed against the metal surface. The modified surface becomes harder and changes shape to form micro dimples, which improves friction and wear characteristics. Additionally, by colliding fine particles at high speeds, the surface is refined, compressive residual stress is imparted, and it becomes tougher. 【Features】 ■ Reduced friction ■ Wear prevention ■ Oil film retention effect ■ Increased fatigue strength *For more details, please download the PDF or feel free to contact us.
