The "OXISO treatment" is a surface modification technology that combines our unique precision shot peening "OX-FSP" and special polishing processing "OX-Polish." 【Effects of OXISO Treatment】 1. Reduction of peeling Reduces the occurrence of peeling on the product surface caused by double flow of molten metal. 2. Reducing voids Improves the flow of molten metal, thereby reducing the occurrence of voids and shrinkage cavities. 3. Prevention of galling The uneven surface of the mold due to FSP treatment enhances cooling effects, which suppresses galling and seizure by improving the retention of release agents. 4. Measures against melting In addition to improved flow characteristics from FSP treatment, applying OX-COAT after FSP significantly enhances resistance to adhesion. 5. Delaying the occurrence of heat cracks FSP treatment refines the crystal grains of the mold, delaying oxidation at the grain boundaries, enabling measures against thermal fatigue through residual compressive stress and increased hardness. 6. Measures against stress corrosion cracking By increasing the fatigue strength of the inner diameter while maintaining high hardness in the mold's water passage, this technology suppresses the occurrence of cracks from the inside, extending the mold's lifespan. ★ As efforts toward carbon neutrality become increasingly necessary, this technology is expected to provide low friction and energy-saving effects. ★ We are currently offering a case study document that introduces treatment examples with photos, available for viewing via "PDF Download."

Our precision shot peening process, "OX-FSP," carefully selects shot conditions based on the material, heat treatment, hardness of the product, as well as the usage environment and its countermeasures. This method is primarily aimed at improving fatigue strength and sliding properties by processing under appropriate conditions. Compared to conventional shot peening, reducing the media size to several micrometers to several millimeters increases the injection speed to over 200 m/sec, allowing for tremendous injection energy even with the same amount of air (processing pressure). This enables the achievement of surface heat treatment effects, high residual compressive stress, and good sliding properties. 【Key Benefits of This Technology】 ■ Heat treatment effects ■ Improved fatigue strength ■ Enhanced oil film retention ■ Reduced friction *For more details, please download the PDF or feel free to contact us.

We would like to report the measurement results of cutting tools processed with our precision shot peening "OX-FSP." According to a technical report from Company T, it has been confirmed that the lifespan of cutting tools has improved by more than 1.5 times, resulting in reduced costs. Additionally, it contributes to cost reduction due to the improved lifespan of welded tips and the lifespan enhancement from cutter OX treatment. [Discussion] - It is believed that after regrinding the cutting tools and processing them, the "rake face" and "clearance face" are strengthened, resulting in reduced wear. - The burrs on the regrinded surface are removed through processing, improving surface roughness, which facilitates smoother chip flow and works towards reducing wear. We are introducing numerous processing examples along with product photos. *For more details, please refer to the PDF materials or feel free to contact us.

Through the micro-particle precision shot peening "OX-FSP" and the oxo special polishing process "OX-Polish," it is possible to simultaneously achieve "fatigue strength enhancement" and "low friction characteristics," enabling the formation of OXO's unique plateau structure (special dimples). Typically, plateau structures formed by machining allow oil to escape along cutting marks during sliding. However, by forming tiny depressions through "OX-FSP treatment" and polishing the protruding parts with "OX-Polish," we create oil reservoirs and produce a surface with excellent oil film retention. Additionally, the surface exhibits high hardness, high compressive stress, and low friction properties. The change from surface resistance to point resistance also contributes to friction reduction. *For more details, please download the PDF or feel free to contact us.
