Copper and copper alloys are treated with a chrome-free KIRINS process. Fully compliant with RoHS.
We will perform a chrome-free Kiring treatment (i.e., pickling and discoloration prevention treatment) on copper and copper alloys. Conventional Kiring treatment involves immersion in hexavalent chromium solution. I believe there are many vendors who are lagging behind in this regard. Please let us handle the treatment for you.

Company information
We are plating small products such as screws and precision parts (compatible with φ0.6 mm) using a barrel. We offer various types of plating including zinc plating (trivalent white, black, red, blue, yellow, green, purple, pink / hexavalent colored chromate, hexavalent black chromate), nickel plating (glossy, matte, double nickel, copper under nickel, black nickel, stainless steel compatible), high nickel zinc alloy plating (stainless steel compatible), lead-free electroless nickel plating, tin plating, black dyeing (iron, brass, stainless steel compatible), passivation treatment, and non-chrome Kirins treatment, among others, with various combinations available. We will flexibly process according to the shape, material, surface condition, and quantity of each product. (We can process from a single screw.) Please entrust us with items that frequently cause issues with automatic plating equipment. We will finish them beautifully without any problems.
