We kindly ask for your continued support and patronage. 【Business Activities】 ■ Industrial chrome plating, industrial copper and nickel plating, electroless nickel plating, precision machine polishing and grinding, and general metal surface treatment. *For more details, please refer to the PDF materials or feel free to contact us.

• Processing Contract
• Surface treatment contract service

Electrolytic copper and nickel plating have relatively low stress and can be applied in millimeter thicknesses. Our main products include base plating for conductor rolls for steel manufacturers and repairs of collector rings aimed at dimensional restoration. For more details, please contact us or check our website.

• Plating Equipment

This is a plating obtained by immersing a substrate in an aqueous solution containing nickel salts and hypophosphorous acid (reducing agent). The electrons released by the oxidation of the reducing agent transfer to nickel ions, resulting in the deposition of a nickel-phosphorus alloy coating. Unlike conventional electroplating, this process does not rely on electric forces, which is why it is referred to as electroless nickel-phosphorus plating.

• Plating Equipment

Industrial chrome plating is widely used as a metal surface treatment technology that enhances corrosion resistance, particularly wear resistance. The most important requirement for industrial plating is to "uniformly apply a thick coating with good adhesion to the base material," which necessitates numerous operational processes for chrome plating. Leveraging our long-standing experience and technical expertise since our founding, as well as equipping our Okayama factory with large-scale facilities, we respond to the diverse needs of our customers.
