The dimples on the processed surface form oil reservoirs and significantly improve friction and wear characteristics!
"WPC processing" is a type of cold working that involves high-speed collisions of fine particles (media) measuring several tens of micrometers against the surface of metals, forming countless tiny dimples while simultaneously strengthening only the surface layer. This process enhances fatigue strength by introducing compressive residual stress and refining the crystal grains. As a result, it is increasingly being used as a surface modification technology to improve 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-peens the metal surface 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 parts. 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 have become possible for aluminum materials, which were previously difficult to coat. 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 increased several times! Further durability and friction reduction can be expected through composite processing combined with nitriding, carburizing, high-frequency hardening, and coating. We offer short delivery times, and orders can be placed from just one piece, including composite processing.
