Consistent manufacturing from highly accurate custom precision turning and grinding, including heat treatment, surface treatment, and OD polishing to sub-assy.

〇We are Specialists in precision turning and grinding.
〇Support from prototype , small-run to mass production
〇Extensive experience in processing difficult-to-cut materials such as titanium and Kovar.
〇Hard turning on high hardness materials’ products after heat treatment.

Our leading products include but are not limited to:
 Spools,Sleevs,Cartridges and futer for Hydraulic components and other fluid control components
 Various parts for Semiconductor manufacturing equipment.
 Special Screws

Since 2013 ,we have also been manufacturing custom prodcts at the VSIP Hai Phong industrial complex in Vietnam and are currently building a new factory in Nam Cau Khieem

Besides, we developed an in-house Production Management system and started to provide them to clients.
