The dimples on the processed surface form oil reservoirs, significantly improving friction and wear characteristics!
"WPC processing" is a type of cold working that forms countless tiny dimples on the surface of metals by colliding fine particles (media) of several tens of micrometers at high speed, while simultaneously strengthening only the surface layer. It achieves improved fatigue strength through the application of compressive residual stress and the refinement of crystal grains. For this reason, it is increasingly being used as a surface modification technology to enhance strength and functionality in various metal products such as machine parts, cutting tools, and molds.

Company information
As a leading company in WPC processing, we achieve further reduction in friction and improvement in wear resistance and seizure resistance by combining it with other surface treatments such as DLC/PVD coating. WPC processing continuously shot-blasts metal surfaces with micro-sized media, generating residual compressive stress on the surface while simultaneously forming countless micro-dimples, significantly improving the fatigue strength and sliding characteristics of sliding components. Fujii WPC Co., Ltd. boasts a wide range of processing achievements in industrial fields, from automotive parts to molds, cutting tools, and other tools, as a leading company in WPC processing. With composite processing using DLC coating, high-quality coatings are now possible even on aluminum, which was previously challenging. Additionally, by applying WPC as a pre-treatment for PVD coatings on molds, cutting tools, and other tools, we can further enhance the excellent performance of PVD. The lifespan of automotive parts, metal components, molds, cutting tools, and other tools can be multiplied several times! Composite processing combined with nitriding, carburizing, high-frequency hardening, and coating is expected to provide further durability and friction reduction. We offer short delivery times and can accommodate orders starting from one piece, as well as composite processing.
