◆To impart adhesion, wear resistance, and decorative properties to the surface of core materials (brass, zinc alloys, etc.), we apply several types of plating in stages, primarily using copper, tin, zinc, and gold.

◆We meticulously adjust the type of part and the thickness of the coating to maintain quality. While it varies by product, we generally apply three layers of plating.

◆We conduct rigorous quality control inspections, so please rest assured regarding the quality.

◆Longevity depends on usage environment and care.
