"WPC processing" is a technology that modifies metal surfaces by mixing fine particles with a compressible gas and colliding them at high speed against the metal surface. The modified surface becomes harder and changes shape to form micro dimples, which improves friction and wear characteristics. Additionally, by colliding fine particles at high speeds, the surface is refined, compressive residual stress is imparted, and it becomes tougher. 【Features】 ■ Reduced friction ■ Wear prevention ■ Oil film retention effect ■ Increased fatigue strength *For more details, please download the PDF or feel free to contact us.

"WPC processing" is a surface modification technology that involves mixing fine particles of a material suitable for the intended purpose with a compressible gas and colliding them at high speed onto the surface of metal products. By introducing strong processing into the local area of the surface, it is possible to add fine crystalline layers, nano-crystalline layers, and compressive residual stress. Additionally, it forms micro dimples on the surface, which improves friction and wear characteristics due to shape effects such as oil reservoirs. 【Added Functional Surfaces】 ■ Sliding properties ■ Release properties ■ Fluid control ■ Durability ■ Optical properties *For more details, please download the PDF or feel free to contact us.

We would like to introduce the measures and enhancements for the weak points of the 86/BRZ, assuming high loads during circuit driving. In the case of the 86/BRZ, the CVJ runs directly under the exhaust, making it susceptible to heat damage, and additionally, due to the influence of VSC, there are many occurrences of CVJ breakage. By performing WPC treatment, we increase fatigue strength and simultaneously exhibit a temperature suppression effect due to reduced friction, thereby improving the durability of the CVJ. 【Related Products (Partial)】 ■ CVJ (Constant Velocity Joint) ■ Shift Fork Shaft/Bush ■ Synchro ■ 4-Speed Collar ■ Complete Transmission ■ Recommended Transmission Oil for 86/BRZ *For more details, please download the PDF or feel free to contact us.

"WPC processing" is a type of cold working that involves colliding fine particles (media) at high speed against the surface of a metal to create countless tiny dimples while simultaneously strengthening only the surface layer. The dimples on the processed surface form oil reservoirs, significantly improving friction and wear characteristics. Additionally, by applying strong processing to the very surface of the metal, it achieves fine crystallization and enhances fatigue strength. 【Added Functional Surface Features】 ■ Lubricity ■ Release properties ■ Fluid control ■ Durability ■ Optical properties *For more details, please download the PDF or feel free to contact us.

We would like to introduce the metal surface treatment by Fujii WPC Co., Ltd.

We take pride in being a company that attracts attention in the field of surface treatment technology research, spanning from motorsports to industrial, medical, and food sectors. 【Technology】 ■ WPC Treatment ■ Hyper Moly Shot ■ WPC Treatment + Hyper Moly Shot ■ DLC Coating ■ Tin Shot *For more details, please download the PDF or feel free to contact us.

"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. [Added Surface Functions] ■ Lubricity ■ Release properties ■ Fluid control ■ Durability ■ Optical properties *For more details, please download the PDF or feel free to contact us.

"WPC processing" stands for Wide Peening Cleaning, which is a type of shot peening (impact method). It doubles the passability by improving slip properties, reduces clogging, and minimizes material loss. It suppresses adhesion and allows for easy cleaning with air. It forms uneven surfaces and reduces contact area. In other words, since it is not a coating, you can use it with confidence. 【Benefits】 ■ Increases productivity ■ Improves yield ■ Reduces cleaning time ■ Cuts labor and utility costs ■ Measures against foreign matter contamination *For more details, please download the PDF or feel free to contact us.

We would like to introduce examples of processing and handling of our "beauty and medical devices." Titanium (64 titanium), which is lightweight, hard, and has no impact on the human body, is a material commonly used in the medical field. By applying WPC treatment to this 64 titanium, there are various benefits such as improved surface hardness (approximately 1.7 times) and increased fatigue strength. Currently, we are also conducting mass production for surgical instruments used in endoscopic surgery for Company O.

We would like to introduce the "WPC processing case study of M6 taps" that we conducted. Before WPC processing, the edges were sharp, and there were burrs present, with strong tool marks. After WPC processing, the burrs were removed, and a uniform oil reservoir was formed, resulting in a uniform pearlescent surface with weakened tool marks. 【Case Overview】 ■Before WPC Processing - The surface in new condition shows chips and burrs. ■After WPC Processing - The machining marks have become faint, and a uniform dimpled surface has been formed. - Burrs have been eliminated, allowing for stable edge rounding. *For more details, please download the PDF or feel free to contact us.
