Process and Machining Capabilities
Precision Die Cast process focuses on die/mold accuracy, gate venting, shrinkage control, post-machining allowance and inspection datum. Small precision housings need to focus on screw bosses, interface holes, thin-wall structure and appearance surfaces; connector need to focus on hole spacing, perpendicularity, assembly clearance and load-bearing edge; heat dissipation parts need to focus on base plate flatness, fins forming, thermal contact surface and post-machining datum.
The production process may include die/mold machining, die trial, die casting forming, gate removal, deburring, CNC finishing, tapping, surface treatment, dimensional inspection and packaging. For assembly type parts, will be confirmed according to functional positions add hole positions re-inspection, threads inspect, flatness inspect and sample assembly.

Critical machining surface, appearance surfaces, threaded holes, positioning surface and thin walls corners can perform separately protection, reduce scratches, impact damage and deformation.
Frequently Asked Questions
Q: What is the minimum order quantity (MOQ)?
-
A: Precision Die Cast standard MOQ for 100–500 pcs. Small zinc alloy pcs, aluminum alloy housings and multiple post-machining parts will be confirmed according to die/mold cost and production quantity.
Q: What is the lead time?
-
A: new mold development usually takes 30–50 days, mass production usually takes 15–30 days. High-precision hole positions, multiple post-machining processes and complex surface treatment order lead time will be longer.
Q: Which positions are suitable for CNC post-machining?
-
A: mounting holes, threaded holes, sealing surface, positioning surface, countersinking, reaming and assembly datum surface suitable for through CNC post-machining improve accuracy.
Q: How are assembly dimensions controlled on precision die castings?
-
A: can be achieved through die/mold accuracy, shrinkage compensation, post-machining datum, hole positions inspect, threads inspect and sample trial assembly control assembly dimensions.
Q: Can visible/appearance parts be produced?
-
A: Yes. Visible/appearance parts can be customized according to surface requirements select sandblasting, powder coating, spray painting, electroplating, anodizing or electrophoresis treatment, and during packaging during perform appearance surfaces protection.
