FAQ
Frequently Asked Questions
Can you support PPAP and IATF 16949 documentation?
Our quality system is ISO 9001:2015 certified. We can deliver PPAP packages and full dimensional reports for prototype and pre-production parts. For series production in IATF-certified scope, we work with partner facilities and can introduce you on request.
Do you handle low-volume EV programs?
Yes — this is our core strength. Most of our EV customers run 100–5,000-piece monthly production for niche models, prototype fleets, and aftermarket components. We bridge the gap between R&D and injection molding.
What is the typical lead time for a 1,000-piece automotive order?
2–3 weeks for typical machined parts, plus surface treatment time. We recommend adding 1 week buffer for first articles, anodize / plating, and inspection reports.
