FAQs
What’s your tolerance for auto parts?
Typical tolerance: ±0.05 mm; tighter tolerances are evaluated case-by-case based on geometry, material, and inspection method.
Do you support sample testing?
Yes，We will provide samples for customer inspection at each mold trial stage.
What’s the lead time for mold making?
Mostly will be finished in 40-45 days, but some complex and big mould will spent more time.
Do you provide DFM / mold flow analysis?
Yes，before mold making we make DFM and mold flow analysis for you to check.
How long of the mould warranty period?
The mould warranty period for 1 year(Damage caused by human factors or accident are not within the the scope of warranty), and wearing parts will send to you for free.
