1, ME processing
ME "Micra Etching" is a micro-etching process. Through the process improvement, the ME treatment process developed by our company can increase the adhesion by 30% compared with the traditional NMT process.

2, gradient oxidation
From light to deep color changes, showing a unique and stylish visual effect.

3, white oxidation
OPD developed a white oxidation process based on market demand, breaking through the bottleneck of oxidation color.

4, semi-hard and hard oxidation

5, micro arc oxidation
Microarc oxidation (MAO) is a combination of electrolyte and corresponding electrical parameters, which is based on the instantaneous high temperature and high pressure generated by arc discharge on the surface of aluminum, magnesium, titanium and their alloys. Ceramic film layer. The surface hardness of the product can reach more than 1000HV.
