Electropolishing (EP) and GEP/GEP-W of Nichisho Astec Co., Ltd.
Nichisho Astec's Electrolytic Polishing (EP) / GOLD EP / GOLD EP WHITE
Electropolishing (EP) can be applied uniformly and with high quality regardless of the shape or size of the target item.
Effective electropolishing for high hygiene management and product composition stability "Electropolishing" removes fine burrs and particles from products while forming a chromium-rich passive film that excels in corrosion resistance. It is highly effective for hygiene management and product composition stability required in manufacturing facilities for pharmaceuticals, chemicals, medical devices, semiconductors, beverages, and more. We manufacture jigs and electrodes tailored to various shapes and sizes, and we also accommodate the electropolishing of thin tubes. In particular, the Sasayama factory has been dedicated to the refinement of electropolishing (EP) technology and the accumulation of know-how for over 30 years since 1985 as a specialized electropolishing factory. We have received high evaluations from customers for the range of polishing targets and the quality of the finished products.
