By striking micro media, micron-sized irregularities are formed. It is also possible to modify the surface to a high-functionality plateau structure!
"WPC processing" is a surface modification technology that involves mixing fine particles of a material suited to the purpose with a compressible gas and colliding them at high speed onto the surface of metal products. By introducing strong processing into the local areas of the surface, it is possible to add fine crystal layers, nano crystal layers, and compressive residual stress. Additionally, it forms micro dimples on the surface, which enhances friction and wear characteristics due to shape effects such as oil reservoirs. 【Added Functional Surfaces】 ■ Lubricity ■ Release properties ■ Fluid control ■ Durability ■ Optical properties *For more details, please download the PDF or feel free to contact us.

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.
