Surface Technology

The hand-held machine is equipped with different types of professional grinding pieces and cleaning cloth to remove oil from drawing, finishing and polishing.

After the brushed and textured workpiece is soaked in a special anti-oxidation solution, the workpiece is sprayed with a special metal fluorocarbon paint and baked in a high temperature oven to harden it to prevent oxidation of the copper surface.

The copper plate is heated by electricity and gas to increase the ductility of the copper plate, and various reliefs are produced by hand chiselling and forging

A precision CNC laser cutting machine is used to cut the workpiece into different shapes and patterns.

According to the pattern, the one-to-one model is shaped, and the metal liquid after melting at high temperature is cast, bonded and finely ground according to the model.

After exposure platemaking and development, the protective film of the etched area is removed, and the chemical solution is contacted during etching to achieve the effect of dissolving corrosion and forming the effect of concave and convex or hollow forming.
