The process begins with meticulous surface preparation, a crucial step that ensures the plastic surface is clean and primed for metal adhesion. The plastic parts are first thoroughly cleaned to remove any contaminants like oils, dust, or mold release agents, which could hinder the electroplating process. Once cleaned, the plastic is subjected to a chemical etching process, typically using a chromic acid solution. This etching creates microscopic roughness on the plastic surface, significantly enhancing the ability of the subsequent metal layers to bond effectively.
