Frequently Asked Questions

What is the minimum order quantity (MOQ)?

MOQ depends on the part size and material. For standard parts we usually accept a few thousand pieces; for custom tooling we recommend a sample approval before mass production.

Can you provide samples before mass production?

Yes. We provide T1 samples from the actual mold for your approval, or quick 3D printed prototypes for design verification before tooling.

How do you control product quality?

We follow ISO 9001 procedures with incoming material checks, first-article inspection, in-process patrol inspection and final outgoing inspection before shipment.
