  1. The copper castings and the previously selected abrasives and polishing machines are installed in the drum to directly obtain a good smooth surface, but most of the results depend on the hardness of the copper castings and can be obtained with steel wire.


   2. Painting, electroplating and anode: It can improve the anti-corrosion ability and promote the appearance of copper castings.


  3. Chemical dip coating method: Both can get decorative corrosion-resistant coating, so it can be painted or unpainted. If the demand for abrasion resistance is high, chemical disposal methods alone cannot be pre-treated before painting. The remaining chemical solvents on the surface should be rinsed and wiped dry immediately.
