FAQ
1. What is the typical lead time for custom earphone shell production?
Sample delivery takes 10-15 days, while mass production requires 4-6 weeks depending on order quantity and design complexity.
2. Can you work with our provided design files?
Yes. We accept CAD files (e.g., STEP, IGES) and optimize them for MIM manufacturability upon request.
3. What materials do you recommend for earphone shells?
Stainless steel (316L) is popular for corrosion resistance and aesthetics, while titanium suits premium lightweight designs.
4. Is your MIM process suitable for small orders?
We support low MOQs (1,000 pieces) and scale efficiently for high-volume demands.
5. Do you assist with mold design and optimization?
Absolutely. Our engineering team provides DFM (Design for Manufacturing) analysis to ensure cost-effectiveness and quality.
