電化皮膜工業 List of Products and Services

Denka Film Co., Ltd.'s "Other Metals and Surface Treatment" offers various polishing treatments for metals such as iron, copper, and stainless steel. By applying various surface treatments to metals, we enhance their properties and perform a "makeup" of metals by adding new functions. Additionally, to meet the diverse needs of the times, we are engaged in research and development of "proposal-type" surface treatment methods. [Types] ■ Electroless Nickel ■ Electrolytic Polishing ■ Chemical Polishing ■ Buff Polishing ■ Shot Blast Treatment *For more details, please refer to our catalog or feel free to contact us.

The "chromium-based surface treatment" of the electrochemical membrane industry is superior to conventional hard chrome plating (Hv=700), which is why this Cr-C4 treatment is established as the standard treatment for "hard chrome plating." "BCr (black chrome)" has a uniform micro-crack (velvet-like) structure, achieving high corrosion resistance. Additionally, we have developed a low hexavalent BCr that complies with RoHS. 【Features】 ■ Forms a thin film of 2-3μm, suitable for precision parts ■ Due to the uniform micro-cracks, corrosion current is dispersed, providing high corrosion resistance ■ The velvet-like film serves as a pre-treatment for painting and coating parts ■ Implements work processes in accordance with MIL-DTL-14538D ■ Developed a low hexavalent BCr compliant with RoHS (removal of residual hexavalent chromium) *For more details, please refer to the catalog or feel free to contact us.

The "anodizing (alumite) technology" of the electrochemical film industry supports a wide range of alloys, including general anodizing with film thicknesses from 3 to 25 μm, as well as industrial aluminum castings that are difficult to color. 【Features】 ■ Decorative anodizing (glossy, matte, hairline, buffed) ■ Dyed anodizing (black, gold, red, blue, brown, green, gray) ■ Hard anodizing (HA) ■ Special hard anodizing (SHA) ■ Compatible with chemical treatment *For more details, please refer to the catalog or feel free to contact us.
