What is surface treatment?

Mainly used for rust prevention and corrosion resistance! Introducing the surface treatment performed in the final process.

Surface treatment after sheet metal manufacturing is mainly used for rust prevention, corrosion resistance, insulation, etc. Well-known methods include painting and plating. Painting (metal baking paint) involves spraying various colors of paint onto the surface of the metal for purposes such as rust prevention and improving appearance, followed by placing it in a high-temperature furnace to bond the material and paint. Plating is a method of surface treatment where the product is immersed in a plating solution in a tank called a plating bath, causing a chemical reaction. 【Features】 ＜Painting (metal baking paint)＞ ■ The temperature is maintained in a furnace at around 100 to 200 degrees for an extended period. ＜Plating＞ ■ There are quite a few types, broadly categorized into gold, silver, copper, zinc, nickel, tin, etc. ■ Although they have different names, there are also processes similar to anodizing used for aluminum surface treatment. *For more details, please refer to the PDF document or feel free to contact us.

Rust prevention + friction coefficient management, improving torque management accuracy for screws.

High-performance surface treatment that combines lubricity and high corrosion resistance.

One property that is closely related to surface treatment is the coefficient of friction (slip resistance). Particularly in screw products, variations in the coefficient of friction during fastening can lead to insufficient tightening or over-torque, resulting in various issues such as loosening of screws or indentation of the mating material. Our surface treatment can improve rust resistance while stabilizing within a specific range of coefficients of friction, enabling proper torque management. If you are experiencing issues with screw fastening or the coefficient of friction, please consult us. Additionally, if you are currently applying lubricants separately, our surface treatment can control the coefficient of friction on its own, making it possible to eliminate the use of lubricants. *Please note that the torque coefficient may vary depending on the conditions of the internal threads and the components being fastened.
