Frequently Asked Questions

What file formats do you accept for quotes?

We accept STEP (.stp), IGES (.igs), SolidWorks (.sldprt), and 2D PDF/DWG drawings. Our engineering team provides DFM feedback and a detailed quote within 24 hours.

What is your typical lead time?

Standard lead time is 7-15 business days. For urgent orders, expedited service is 3-5 business days. Prototype orders are typically 5-7 business days.

What tolerances can you achieve?

Standard machining tolerance is ±0.01mm (ISO 2768-m). For high-precision requirements, we can achieve ±0.005mm on critical dimensions with full CMM inspection reports.

What materials do you work with?

We machine steel alloys (P20, H13, S136, 718H, NAK80), stainless steel (304, 316L), aluminum (6061, 7075), brass, copper, engineering plastics (POM, PEEK, PTFE), and titanium.

Do you handle both prototype and mass production orders?

Yes. From single-piece prototypes to 10,000+ production runs. Our scalable manufacturing allows seamless transition from prototyping to volume production.
