FAQ

What is your minimum order quantity?
There is no fixed minimum. We run prototype batches of a few hundred parts and scale to over a million units a year.
How do you protect my design files?
We sign an NDA before receiving any CAD files. Each mold is dedicated to your project and stored securely.
Can you handle medical-grade materials?
Yes. We regularly process medical-grade PP, PC, PEI, medical silicone, LSR, and TPE, and can supply material documentation.
Can you take over a mold from my current supplier?
Yes. Mold transfer is one of our specialties. We receive, validate, and production-prove tooling built by suppliers in China, Europe, and the USA.
What file formats do you accept?
STEP, IGES, STL, Parasolid, SolidWorks (SLDPRT), Creo, and AutoCAD. We review SolidWorks files directly, so you get DFM feedback without a translation layer.
What is your lead time?
Quote within one business day. Mold development in four to six weeks. Production after mold approval in two to four weeks.
Do you ship to the USA and Europe?
Yes, regularly, on FOB, CIF, and DDP terms. We handle export documentation, including material certificates and country-of-origin paperwork.
