Shenzhen Bao’an International Airport is 20 minutes away; Yantian and Shekou ports about one hour.
Capability Summary
3/4/5-axis milling, CNC turning (bar capacity 1-300mm), Swiss-type machining, surface treatment coordination, accuracy to ±0.005mm, and a coordinate measuring machine (CMM) for verification. ISO 9001:2015 and ISO 14001:2015 certified.
Quality You Can Audit
Every order ships with in-process inspection records. Our CMM verifies critical dimensions against your drawing on first article, at batch start, and at final release. Material certificates (EN 10204 3.1) and full dimensional reports come standard; PPAP and FAIR documentation are available on request for automotive and industrial programs.
Visiting & Logistics
Standard lead time is 3-7 days for prototypes and 7-15 days for production batches, with surface treatment adding 5-10 days. Parts are cleaned, protected against corrosion and scratching, and packed in customized trays or EPE foam for international shipping. DFM feedback on RFQs is returned within 24 hours.
Why Work With Us
One supplier from drawing to finished part: milling, turning, 5-axis and Swiss-type machining are all in-house, together with anodizing, plating, laser marking, and silk-screen coordination. You get one accountable partner instead of a chain of subcontractors.
