We would like to introduce our handling of "electroplating." "Zinc-nickel alloy plating" achieves high corrosion resistance with a nickel eutectic amount of 12-15 wt%. Its corrosion resistance is 4-5 times greater than that of zinc plating, and it also excels in solderability, weldability, and paint adhesion. "Noble metal plating (gold and silver)" is used for products that require high reliability in conductivity, durability, and weather resistance. We can propose coatings that meet the required specifications, even in small quantities. 【Features of Zinc-Nickel Alloy Plating】 ■ High corrosion resistance achieved with a nickel eutectic amount of 12-15 wt% ■ Excellent solderability, weldability, and paint adhesion ■ Environmentally friendly trivalent chromate treatment is performed ■ Over 200 hours of white rust occurrence at 5%, over 1000 hours of red rust occurrence (salt spray test) ■ Used in components around automobile engines *For more details, please refer to the PDF document or feel free to contact us.

"Fluorine Lubricating Plating (Fluorine Resin Composite Electroless Nickel Plating)" is characterized by excellent lubricity and is used for various purposes, including slip resistance, water repellency, oil repellency, and sound dampening. Since it is based on electroless nickel, uniform plating treatment is possible. The processing methods include barrel processing, racking processing, jig processing, and batch processing. As a base plating, electroless nickel is applied at approximately 1 to 2 μm, followed by the fluorine lubricating plating treatment. We have achieved plating thicknesses of up to 30 μm. 【Features】 ■ Excellent lubricity ■ Used for slip resistance, water repellency, oil repellency, and sound dampening ■ Uniform plating treatment is possible due to the electroless nickel base ■ Capable of barrel processing, racking processing, jig processing, and batch processing ■ Achieved plating thicknesses of up to 30 μm *For more details, please refer to the PDF document or feel free to contact us.
