Polymer diffusion welding is a product used for welding busbar expansion joints and soft connection conductive belts. It achieves the purpose of adhesive welding by allowing molecules to penetrate each other between copper strips through high temperature and high pressure. Welding can be achieved without the need for solder, and the quality after welding is qualified, with a smooth and exquisite appearance. The polymer diffusion welding machine adopts high-frequency transformers with low voltage, which can effectively reduce insulation and ignition problems caused by high voltage and enhance the reliability of the equipment.
