Super high corrosion-resistant surface treatment with trivalent chromium chemical treatment on an alloy plating of 85% zinc and 15% nickel.
Ultra-high corrosion-resistant surface treatment with approximately 10 times the corrosion resistance of trivalent white and trivalent black. It is common to apply this treatment to M6 to M8 bolts or M3 to M4 small screws, but our company can also process precision parts with diameters ranging from 0.8 to 2.0 mm. There are two types of finished colors: blue-black and jet black.

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.
