Electropolishing of stainless steel that maximizes its performance.
**Features of Stainless Steel Electrolytic Polishing** ◆ Achieves a Clean Surface By dissolving the stainless steel surface, it removes foreign substances and fine dirt that are difficult to eliminate through physical polishing, resulting in a clean surface with good washability. ◆ Provides High Corrosion Resistance As a result of forming a more robust and stable passive film rich in chromium, it results in a surface with high corrosion resistance. ◆ Produces Gloss It results in a surface with a different roughness and gloss compared to buff polishing. It can be used as an alternative to buff polishing or in combination with it. ◆ Allows Polishing of Areas Not Possible with Buff Polishing There are areas that cannot be polished due to the size of the polishing tool in physical polishing. Electrolytic polishing can effectively polish such fine areas. ◇◇ For more details, please download the catalog or contact us ◇◇

basic information
Electrolytic polishing is a polishing method that achieves a polishing effect by flowing direct current through an electrolyte solution between the product placed on the positive side and the negative electrode, thereby dissolving the metal surface. 【Applicable Materials】 - Austenitic (SUS304, SUS316, etc.) - Ferritic (SUS430, etc.) - Martensitic (SUS410, SUS420, etc.) - Duplex (SUS329, etc.) - Precipitation hardened (SUS630, etc.)* - For other steel types, please inquire. *The finish may vary depending on the heat treatment condition. 【Processing Capacity】 - Proven track record of tens of thousands of items from very small to extra-large products. - Capable of handling everything from single prototypes to mass production. - Large lot items can also be accommodated with fully automatic electrolytic polishing equipment. ◇◇ For more details, please download the catalog or contact us ◇◇

【Surface Treatment Example】 Electrolytic Polishing of Pipe Interior This is a case of treatment where electrolytic polishing was applied to the interior surface of a pipe. Before electrolytic polishing, there were buffing marks and discoloration, but after electrolytic polishing, the buffing marks and discoloration were removed, resulting in a clean and smooth surface.

Company information
Our company has been engaged in surface treatment technology for over 60 years, incorporating the philosophies of ISO 14001 and ISO 9001 into our processes, from metal houseware products to semiconductor manufacturing equipment components. Through thorough quality control and technological development, we provide surface treatment processing that meets the demands of the times. Our electrolytic composite polishing has received high praise, including a letter of appreciation for contributing to the completion of the high-intensity proton accelerator facility "J-PARC," which was jointly constructed by the Japan Atomic Energy Agency (JAEA) and the High Energy Accelerator Research Organization (KEK). We perform various surface treatments that maximize the qualities of different metal materials, such as electrolytic polishing, electrolytic composite polishing, coloring of stainless steel and titanium, and pickling. In recent years, we have also been involved in surface treatment processing for materials like magnesium, aluminum, and titanium. Leveraging the expertise in surface treatment that we have cultivated in the Niigata Prefecture Tsubame-Sanjo region, which is well-known for metal processing, we are here to assist you in solving your problems.
