Materials We Process
CNC milling, turning, 5-axis, Swiss-type, surface treatment.
Scope of Service
- one-stop from drawing to finished part
Capability Highlights
Accuracy to ±0.005mm capability, verified on a CMM. Machine park includes 3/4/5-axis machining centers, CNC lathes and Swiss-type machines, with in-house fixture design and CAM simulation for first-pass success.
Quality System
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.
Lead Time & Packaging
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 Customers Stay
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.
