Product Description

1. Company Profile
Shenzhen Surfacing Technology Co., Ltd Located in Fuyong, Shenzhen, China, we are leading Metal Injection Molding (MIM) and physic vapor deposition coating (PVD) manufacturer in Shenzhen, China. Advanced technology and equipments, skillful work force, experienced technical and management team, stable material supply, and good quality control system insure we produce high quality MIM parts and PVD coating.
MIM technology is new technology wildly used to make precious, high density, high accuracy complicate metal parts. MIM parts have better tolerance compared to PM parts and lower mass production costs compared to CNC. Our MIM plant started in 2005. The annual capacity is 70 tons parts from our continue line and batch furnaces. We use high efficiency debinding technology and very stable feedstock from BASF to make 316L, PH 17-4, iron base, copper base, and other kinds of precious metal parts, like mobile phone keys, windows and etcs, tools, machine parts, cable connectors, belts, electronic devices parts, jewelry and etc.
