Business Areas

• Electropolishing: It is a non-contact polishing method between an electrode and a workpiece, improving surface flatness, gloss, and corrosion resistance, and is suitable for polishing complex shapes, high-hardness materials, and difficult-to-cut materials that are challenging to process mechanically.
• Precision Cleaning: We systematically and comprehensively remove contaminants such as films, particles, adsorbed gases, metal atoms, and ions from the surfaces of various equipment and components used in manufacturing processes for semiconductors, LCDs, organic ELs, and advanced chemical products using polishing and cleaning technology.
• SBB / Sanding: Shot blasting (SBB) is a method of detaching scale, rust, welding burrs, etc., and adjusting surface roughness by spraying hard particles, while sand blasting (GBB) is a method of finishing metal product surfaces cleanly by spraying sand with compressed air.
