A Lower-Cost Way to Produce Large Batches
Do you need more than 10,000 parts per year? CNC machining of die castings is a smart choice. The rough parts are produced via die casting, using ADC12 or A380 aluminum. The cost of these rough parts is only 30% to 50% of pure CNC machining. We then perform CNC turning and milling on critical surfaces, including mounting faces, threaded holes, and bearing holes. This saves money without compromising quality. Our company has 9 senior technical staff to support you.
How We Ensure Accuracy
Raw die castings have low dimensional accuracy, typically around ±0.1 mm. CNC machining of die castings improves critical dimensions to ±0.01 mm, allowing parts from different batches to be interchangeable. Positional accuracy reaches ≤0.05 mm, and hole tolerances meet H7 grade. Burrs are removed during machining, leaving smooth edges-no secondary cleaning is required. This saves labor time and costs.

Two Tests That Protect Your Order
Before CNC machining, every batch of die castings undergoes X-ray inspection according to ASTM E505, checking for air holes and shrinkage. Only qualified rough parts proceed to CNC machining. After machining, we inspect all hole sizes with an air gauge, testing 100% of the parts. Defective parts never leave the factory. We also comply with local environmental regulations. Third-party inspections are welcome, and we provide material certificates and dimensional test reports.
