[Case Study of Conductive Diamond Technology] Pre-treatment for Resin Plating

Chrome-free, heavy metal-free resin plating pretreatment technology

We would like to introduce a case study of conductive diamond technology that has realized an alternative to chromic acid used in the plating process of automotive parts. Car front grilles, door knobs, and other components are plated on resin, but resin does not conduct electricity and cannot undergo electroplating. Chromic acid is used to dissolve (etch) the resin, fix the catalytic metal, and perform the plating process. This technology uses a solution electrolyzed with a diamond electrode from a sulfuric acid solution, making it a clean and environmentally friendly alternative technology that does not involve toxicity or waste. Additionally, the sulfuric acid solution can be reused, reducing wastewater. [Case Overview] - Dissolves (etches) resin with chromic acid, fixes catalytic metal, and performs plating. - Expected as a clean and environmentally friendly alternative technology that does not use chromic acid. *For more details, please download the PDF or feel free to contact us.
