Precision Machining

At Jinyuan, our success as a contract manufacturer is built on precision CNC machining services that can accommodate the needs of the most demanding industries. We operate a modern well-equipped facility and specialize in low- to middle-volume manufacturing. With our technical capabilities and equipment assets, we handle parts with complex geometries and tight tolerances.

 

Our machining department incorporates a powerful lineup of multi-axis, multi-spindle machinery with live tooling capabilities, automated bar feeds, and pallet systems that allow for greater productivity through lights-out manufacturing.
