Automotive Wrench Bend Part

The post-processing of automotive wrench bending parts primarily involves surface treatment of the sheet metal products, which is to apply a coating on the surface for material protection, preventing oxidation, and enhancing the adhesion of the baked paint. The processes include electroplating, electrostatic adsorption, baking paint, oxidation treatment, etc., with electrostatic adsorption mainly used for cold-rolled sheets. The sheet metal parts are basically finished after the post-processing.
