Electroplating

We adopts 130℃ high temperature electroplating, which makes the finishing not easy to fade. In the situation that Chinese Government is getting more stricter with the environmental pollution, so more and more electroplating factories are shut down. Our electroplating factory invest a lot of money for the pollution disposal machines, making sure we are producing in green and we are friendly to our environment.  In addition, the electroplating factory, is in the leading position in our area.

Polishing

Polishing is always important. We have our own polishing plant with around 15 experienced workers. First of all, we use rough (big abrasive grain) abrasive belts to polish the “flashes” and “gate marks”. Secondly, we use fine (small abrasive grain) abrasive belts to polish the shapes. Finally we use cotton wheel to polish the gloss surface. In this way, the electroplating will not have the air bubbles and waves.

Automatic production

Since 2020, we have invested over 500,000USD for Automatic production equipment. Until now, we have sets of auto Cnc machine, 2 set of auto die casting machine, and 3 sets of auto drilling machine. In addition, we also invested 2 sets of auto polishing machine--Mechanical arm. In this way, all of our products could adopt same production standard. In busy season, due to automatic machines, we could become a 24-hours factory, to meet the customer's order requirements.
