Customized stainless steel rotary joint precision casting hardware parts

We can produce various custom Rotary Unions and Rotary Joints with our stainless steel casting and machining capabilities.Rotary Unions and Rotary Joints is mainly used in the connection, control, direction change, split, seal, and support.

Rotary Unions and Rotary Joints
Rotating Unions and Rotary Joints (also known as rotary swivels, rotary couplings) are precision mechanical devices used to transfer fluid from a stationary source, such as a supply pipe, into a rotating piece of machinery. Rotating Unions and Rotary Joints are used in numerous manufacturing processes to cool, heat, or transfer fluid (pneumatic or hydraulic) power.

Our Quality control

1) We possess a large scale of foundry and CNC machines, as well as production lines of lost wax casting to cater to the need of growing precision investment casting business. Besides, we have advanced inspecting instruments such as Spectrometer, Metallographic Microscope, Tension Tester, and Impact tester for Chemical & Physical Analysis, and 2D projector, X-ray, Ultrasonic , magnetic to keep inner good instruction, CMM to assure dimensional precision.

2) Quality control starts the minute the precision investment casting raw material arrives the foundry, continues along with every stage of investment casting process. We were awarded with ISO9001:2000 by SGS, PED/AD2000 by TUV.

3) We have developed and manufactured more than 3300 types of precision investment casting products, which are widely applied in Auto Parts, Construction Hardware, Marine Hardware, Pumps & Valves, Machine Parts and other industries. A large percentage of our investment casting parts were exported to Europe, US, Japan and Asia.
