FAQ
What is the minimum wall thickness?
Aluminum parts: 0.8–1.2 mm depending on design; Zinc can be thinner. Optimized via DFM and trials.
Lead time for samples and production?
Soft tooling samples: 2–4 weeks; steel molds: 4–8 weeks depending on complexity.
How do you control porosity?
Optimized gating, venting, alloy control, vacuum die casting, X-ray inspection; leak testing for airtight parts.
Do you offer CNC machining and assembly?
Yes, from raw casting to finished products with CNC, assembly, and testing.
