3. Material Range

Aluminum 6061-T6 / 7075-T6 / 5052-H32 / 2024-T3 Stainless 304 / 316L / 303 / 4340 / 17-4 PH Copper C110 / Brass C360 / BeCu C172 Titanium POM (Delrin) / PEEK / Nylon / PTFE / ABS

Common alloys kept in stock for fast turnaround; special orders typically arrive within 3–5 business days. EN 10204 3.1 material certificates available.

4. Quality Process

1. DFM review — engineers check drawings for machinability, tolerance stack-up and cost before quoting.
2. In-process verification — critical dimensions checked mid-run with CMM and precision gauges.
3. First-article & sampling — CMM inspection per AQL; full dimensional report on every order.
4. Calibration — all machines calibrated quarterly; spindle runout re-checked before each run.
5. Traceability — raw stock to finished part, with material certs on request.

5. Lead Time

Stage	Typical
Prototype rush	3–5 days
Standard samples	7 days
Small batch (10–50 pcs)	10–15 days
Mass production	15–30 days
Quoting	Detailed quote within 24 hours
