High-Quality Solid Copper Busbar for Charging Stations - China Suppliers and Factory Custom Solutions
⚙️Processing Technology for Copper Busbar
Cutting Process
Utilizing high-precision laser cutting equipment, non-serrated cutting can be achieved, with smooth cuts and a small heat-affected zone. For thick copper bars, water jet cutting technology can also be selected to avoid the risk of thermal deformation.
Bending Forming
Using a CNC bending machine, the bending angle and radius can be precisely controlled, enabling multi-angle bending. The progressive bending process is adopted to prevent the copper bars from deforming or cracking. The bending radius is more than 1.5 times the material thickness, ensuring that the copper bars can be efficiently routed in compact spaces such as switch cabinets and bus ducts.
Surface Treatment
We offer electroplating processes such as tin plating, nickel plating and silver plating, as well as coating spraying for organic layers. The tin plating process can enhance the oxidation resistance and welding performance of copper strips, while the silver plating can improve the conductivity and high-temperature resistance. The organic coating can be used for anti-corrosion and insulation purposes.
