FAQ

Q: How to choose CNC or die-casting process?

A: Decision based on order quantity and structural complexity:

CNC: small batch (<500 pieces), complex structure (deep cavity/thin wall), high mechanical performance requirements (7075-T6).

Die casting: large batch (>3000 pieces), regular structure, cost-sensitive projects.

Q: How to ensure that thin-wall processing does not deform?

A: Adopting multi-process stress release technology and high-speed low-cutting force processing parameters, combined with vacuum fixture fixation, ensures that the flatness of thin-walled parts is ≤0.1mm/m².

Q: Can batch processing consistency be achieved?

A: Equipped with an online detection system (Renishaw probe), real-time compensation for tool wear, and batch workpiece size fluctuations are controlled within ±0.03mm.

Q: Does it support EMC electromagnetic shielding design?

A: Yes! Through CNC machining of continuous conductive surface + nickel plating, the shell shielding effectiveness reaches 60dB (10MHz-1GHz).

Q: Is the customization cost much higher than traditional processes?

A: CNC machining saves mold opening costs, and the comprehensive cost of small batch orders is lower. In addition, aluminum alloy is 100% recyclable, which is more economical for long-term use.

Q: What is the production cycle and minimum order quantity?

A: 1 piece minimum order, samples are delivered in 10-15 days, and batch orders are completed in 20-30 days.
