Electroforming is divided into three categories: decorative electroforming, functional electroforming, and protective electroforming. Decorative electroforming is used to decorate the mold surface and is often used in experiments, while functional electroforming processes mold components and is often used in actual production. So, what role does protective electroforming play? Let's take a closer look. Protective electroforming generally involves galvanizing, which simply means preventing corrosion and protecting the plated parts. In layman's terms, it's like sacrificing the anode to protect the cathode. Therefore, we can conclude that it also protects the mold during electroforming.
