WPC treatment
WPC - Wide Peening and Cleaning. Widely used in the motor sports including F1, Le Mans, cart, and drag racing vehicles. By firing the ultra fine particles towards the surface of the product at very high speed, thermal discharge brings the repeated effect of heat treatment and tempering in a very short time. The surface of the product produces a new ionic structure and becomes harder and more tenacious. At the same time, it creates hardened layer of a depth and works against metal fatigue.
