By applying WPC as a surface treatment for DLC coating, a surface with excellent tribological properties is formed!
"DLC coating" is a technology that involves coating a nanometer-thin film, primarily composed of carbon and hydrogen, onto metal surfaces. It is an advanced surface treatment technology that achieves high effectiveness in low friction, high durability, high hardness, and corrosion resistance. Our company has successfully developed a technology that combines DLC coating with WPC treatment. By combining these, we can enhance adhesion and further prolong the effects over time. 【Features】 ■ Suppression of oil temperature rise ■ Improvement of transmission lifespan ■ Enhanced piston sliding properties ■ Reduction of mechanical noise ■ Improved engine feel *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.
