Metal Custom Copper Stamping process sequence:
1-Punching: The stamping process (including punching, blanking, trimming, cutting, etc.) that separates the sheet.
2-Bending: The stamping process of bending the Red Copper Sheet into a certain angle and shape along the bending line.
3-Deep drawing: Copper Stamping Parts process that transforms a flat sheet into various open hollow parts, or further changes the shape and size of the hollow parts.
4-Fine blanking: For products with high blanking precision, products with high requirements on size and surface light can be achieved through fine blanking molds to meet the requirements of the drawings.
5-Local forming: the Copper Stamping process (including flanging, bulging, leveling and shaping processes, etc.) that uses various local deformations of different properties to change the shape of the blank or stamping part.
How to wash and brighten the surface oxidation of red copper parts after processing?
The simple treatment method of copper material after oxidation and rust-the main process flow of chemical method is: firstly carry out the cleaning treatment of oil removal and oxide removal → water washing → Custom Copper Stamping polishing treatment→ Copper Stamping protection treatment. The Copper Stamping Parts processed by this method can not only restore the original luster (or even brighter) of the copper parts, but also prevent the Stamped Copper Terminal from being oxidized and keep the copper parts bright as new for a long time.
One is that the oxidized part of the Copper Stamping Processing surface can be cleaned by surface pickling, but the pickling time is relatively short. After pickling, if the surface is directly touched with hands or touched with water, it will quickly oxidize back.
Another method is to do the surface passivation treatment of the Copper Stamping. The anti-oxidation treatment of the surface lasts longer than the pickling process, and the color of the Stamping Copper Sheet surface after passivation will look better, like rose gold.
