We Are

Nitto Elechemic Co., Ltd. was established in 1959 as a metal surface treatment manufacturer that applies rust-resistant coatings to metal surfaces. Metal surface treatment is a technology that utilizes "metal ions" or "minerals". Since its inception, we have continued to research these metallic ions and explored the ways to utilize our expertise and technology in areas other than metal surface treatment.


Metal Spinning

Metal spinning is a metalworking process that transforms a flat circular metal piece into axially symmetrical round shapes. It is accomplished by a roller positioned against the surface of the metal piece and a mold that is spinning at high speed.



Blasting is a type of metal surface treatment in which an abrasive material is blown onto the product at a high speed to clean or decorate. It gives a matte texture, functionality and design.

Anodized Aluminum

Anodizing is a process that forms a nano-level oxide film on the surface of aluminum to provide durability, corrosion resistance and a highly aesthetic surface. Coloring is achieved by adsorbing dyes into the micropores of the oxide film.
