What is WPC Treatment?
WPC is a proven process that has been utilized for many years in the racing and automotive industry. WPC is not a coating, it is a treatment that enhances the surface to reduce friction and strengthen engine parts. WPC achieves this process by firing ultra fine particles towards the surface of a product at very high speeds. The resulting thermal discharge permanently changes the surface, strengthening structure and creating a harder more durable final product.
Why is WPC Treatment better than other finishes?
The WPC process is unrivalled in treating engine parts and other surfaces that have contact points of friction. WPC is superior because it is not a coating; it is a permanent surface treatment that reduces friction while strengthening the part. It's unique micro-dimple formation pattern greatly reduces friction and is unmatched by conventional methods of surface treatment.
WPC has the capacity to treat carburized, nitrided and plated parts without noticeable dimensional changes, and, upon completion of treatment, no further modifications are required of the parts. The strength and durability improvement on the surface after the WPC treatment is unsurpassed by any current methods.
