Raw materials and processing stages completely free of environmentally harmful substances! Chrome-free surface treatment 'ERIN(R)' developed to protect the environment.
Hexavalent chromium contained in metal plating is a specific hazardous substance defined by the Soil Contamination Countermeasures Act, which causes air pollution, river pollution, and soil contamination. 'ERIN' is a completely chrome-free surface treatment developed to protect the health of our precious planet and employees, without using hexavalent chromium. No environmentally harmful substances (hazardous substances) are used in the raw materials or processing stages. It has excellent thin-film rust prevention capabilities (1-6μm) and wear resistance, allowing for film formation on various metals such as iron, aluminum, copper, and stainless steel. 【Features】 ■ Improved wear resistance (1-3μm) ■ Excellent thin-film rust prevention capabilities (1-6μm) ■ No distortion or dimensional changes due to heat, as it is processed at room temperature ■ Heat resistance (−70 to 750℃: coating) ■ Coating hardness (Hv1000-1200) ■ Insulating coating *For more details, please refer to the PDF document or feel free to contact us.

Company information
Our company has 7 factories in Japan and 1 factory in China, and our strength lies in our ability to provide integrated production from design to machining, metal surface treatment, and assembly. In machining, we own over 100 machine tools and can accommodate everything from small-batch, diverse products to mass production. In metal surface treatment, we are a certified dealer of Raident and boast the top market share in Japan. Additionally, we have developed an innovative surface treatment called "ERIN," which features a ceramic film that offers high corrosion resistance, wear resistance, heat resistance, and voltage resistance on various substrates with different surface and three-dimensional shapes. We do not use hexavalent chromium in our raw materials and are also committed to reducing environmental impact.
