WPC processing <Improvement of fatigue strength>

WPC processing <Improvement of fatigue strength>

Can be processed without dimensional changes in metals such as carbide, cermet, SKD, SCM, stainless steel, and aluminum!

"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.

[Processing Example] WPC Treatment of Cutting Tool M6 Tap

[Processing Example] WPC Treatment of Cutting Tool M6 Tap

The processing marks have become faint, and a uniform dimple has formed on the surface! Burrs are eliminated, allowing for stable edge dulling.

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.

WPC treatment (precision shot peening)

WPC treatment (precision shot peening)

The media used can process fine and precise parts without dimensional changes.

This is an introduction to our WPC treatment (precision shot peening). WPC treatment is a revolutionary process that sprays fine hard balls of approximately 50 to 100 μm at a speed of over 100 m/sec onto the surface of metal parts that have undergone heat treatment and diffusion surface treatment, thereby modifying the surface. Unlike conventional shot peening, the media used is finer, allowing for processing of precision parts without dimensional changes. In recent years, it has rapidly gained popularity, leading to improvements in mechanical properties that could not be achieved with standard heat treatment, and it is widely applied to automotive parts. 【Features】 ■ Improvement of fatigue strength in carburized and hardened products (exemplified by gears) ■ Enhancement of repeated fatigue strength in springs ■ Increased wear resistance and release properties of forged molds and resin molds ■ Extended lifespan of cutting tools ■ Transformation of residual austenite into martensite (metal microstructure modification) *For more details, please refer to the PDF document or feel free to contact us.

WPC processing

WPC processing

Extension of fatigue life and improvement of product destruction strength! Measures against pitching in carburized gears!

"WPC processing" is a surface treatment heat treatment method for metal products, in which shots with a hardness equal to or greater than the product hardness, ranging from 40 to 200μm, are injected at a speed of 100m/sec or more, raising the temperature near the surface above the A3 transformation point. It can significantly reduce the surface abnormal layer of gas carburized products. Additionally, the micro-dimple effect greatly reduces sliding resistance and prevents pitching. 【Features】 ■ Extension of fatigue life ■ Improvement in wear resistance and pitching resistance ■ Prevention of stress corrosion and intergranular corrosion in stainless steel and Inconel ■ Reduction of sliding resistance and fluid resistance, decrease in heat generation, and reduction in wear ■ Improvement in the breaking strength of products *For more details, please refer to the PDF document or feel free to contact us.

Effects of WPC processing

Effects of WPC processing

It is possible to form a high-hardness coating on metal surfaces! Synergistic effects can be obtained through composite treatment.

We would like to introduce the effects of WPC treatment conducted by Fujikihan Co., Ltd. When SKD11 material is subjected to quenching and tempering treatment, the microstructure from the surface to about 10μm is refined, and microcracks at the grain boundaries disappear. The surface hardness of the modified layer increases from 700Hv to 1000Hv, and the internal compressive residual stress significantly changes from 200MPa to 1100MPa. Additionally, when powder high-speed steel is treated, the carbide peak in the microstructure from the surface to about 10μm disappears. 【Features】 ■ Increase in metal surface hardness and improvement in toughness due to microstructural refinement ■ Formation of oil pockets due to micro dimples on the surface, enhancing lubricity ■ Ability to form a high-hardness coating on the metal surface ■ Improvement in fatigue strength ■ Enhanced wear resistance, pitching resistance, and chipping resistance *For more details, please refer to the PDF document or feel free to contact us.

WPC processing

WPC processing

In the drive system components, fatigue strength has significantly improved! This greatly reduces troubles such as shaft breakage.

"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 <Excellent sliding properties with surface microtexturing>

WPC processing <Excellent sliding properties with surface microtexturing>

By striking micro media, micron-sized unevenness is formed. It is also possible to modify it into a high-functionality surface with a plateau structure!

"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.

WPC processing <Extending the lifespan of metal parts and molds>

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.

WPC processing <Powder adhesion suppression>

WPC processing <Powder adhesion suppression>

Improved powder flow, with 1.2 to 2.0 times the permeability! Reduces the hassle of maintenance and replacement due to clogging of the mesh.

"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.
