"Stainless Steel Electropolishing" is a surface treatment that polishes stainless steel materials electrochemically by using the product as an anode. Unlike mechanical polishing, it does not stress the workpiece and leaves no altered layer, allowing for a very clean metallic surface. It also enables fine burr removal, contributing to reductions in labor and costs. Many products that have undergone electropolishing are used in equipment that requires a clean environment, such as semiconductor manufacturing equipment, medical devices, and hard disk drives. 【Features】 ■ Does not stress the workpiece and leaves no altered layer ■ Achieves a very clean metallic surface ■ Allows for a high-quality glossy finish comparable to nickel-chrome plating ■ Selectively removes metal from edges and corners regardless of the shape of the workpiece ■ Enables reliable burr removal *For more details, please refer to the PDF document or feel free to contact us.

We offer a "Same-Day Service for Urgent Items." If you contact us by the day before the desired processing date and deliver the materials to be processed by 9 AM on the same day, we can ship single items or small lots on the same day. We can provide high-precision electroless nickel (Ni-P) plating, as well as fluoropolymer lubrication plating. 【Features】 ■ Prototyping and single items ■ Same-day shipping if received by 9 AM ■ Short delivery times ■ A wide range of options including high-precision electroless nickel (Ni-P) plating and fluoropolymer lubrication plating *For more details, please refer to the PDF document or feel free to contact us.
