1,Preparation of raw materials: copper material is made into copper bar tape through heating, rolling, drawing and other processes.
2, Surface cleaning: remove the iron, aluminium, nickel and other residues on the surface of the copper bar tape.
3,Rolling: the prepared copper bar strip is rolled through the rolling mill and pressed into a certain thickness of copper strip.
4, Passivation: passivate the surface of the copper strip so that it is not easy to oxidise.
5,Electrolytic corrosion: Process the copper strip into a certain specification through electrolytic corrosion of ⑤ Electrolytic corrosion: Process the copper strip into certain specifications by electrolytic corrosion.
6,Surface treatment: After anti-oxidation treatment and other surface treatments, the quality and technical indexes of copper foil meet the requirements of customers.
7,Slitting process: According to the customer’s requirements on the quality, width and weight of the copper foil, the copper foil will be slit by high-precision slitting equipments, and then sorted, tested and packaged.
