Electropolishing (EP) and GEP/GEP-W of Nichisho Astec Co., Ltd.
Nichisho Astec's Electrolytic Polishing (EP) / GOLD EP / GOLD EP WHITE
Electrolytic polishing (EP) can be applied uniformly and with high quality, regardless of the shape or size of the target item.
Effective electro-polishing for high hygiene management and stability of product composition "Electro-polishing" removes fine burrs and particles from products while forming a corrosion-resistant, chromium-rich passive film. It is highly effective for hygiene management and stability of product composition 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 electro-polishing of thin tubes. In particular, the Sasayama factory has been dedicated to the refinement of electro-polishing (EP) technology and the accumulation of know-how for over 30 years since 1985 as a specialized electro-polishing factory. We have received high evaluations from our customers for the range of polishing targets and the quality of the finish.
