Surface treatments we can do:

Most CNC factories only focus on CNC machining but are not good at surface treatment. If the surface treatment of parts does not meet expectations, it will not only increase the cost but also affect the time to market products.

YMP has rich experience in the surface treatment of metal parts, and we will choose a suitable surface treatment process according to different parts' materials and uses.

The common surface treatments of YMP include: electroplating, electrophoresis, painting, powder spraying, sandblasting, polishing, shot blasting, laser engraving, etching, CD pattern, silk screen printing, wire drawing, blackening, anodizing, hard oxidation, thick film oxidation, micro-arc oxidation and so on. No matter what personalized requirements your parts need, we can meet them.
