Our manufacturing (tool design, machining and production) is based in Guangdong, China. We have strong ties (15+ years working relationship) with the factory, which may have some pricing impact.

The tolerances on the high-run part are non-critical (but still need to match the other part for a seamless ultrasonic weld). It's got curved surfaces, and the surface texture was EDM'd on.

Likewise, not at all an expert - but have about 10 injection-moulded products under my belt; I just got back from China pricing out two new projects tooling projects. My email is in my profile if you ever want to reach out!
