Will my drawings be kept confidential?
Yes. We sign NDAs before any files are shared and will never release your designs to third parties. Intellectual property protection is non-negotiable for us.
What surface finishes do you offer?
Anodizing (Type II & III, clear and color), hard anodize, powder coating, electroless nickel plating, zinc plating, passivation, polishing, sandblasting, and more. All finishes are RoHS compliant.
How fast can you deliver samples?
Standard prototypes are ready in 3–7 working days. For urgent orders, contact us directly — we can often expedite to 2–3 days with prior arrangement.
How do you guarantee quality?
Every batch undergoes 100% dimensional inspection using CMM, 2.5D vision systems, and precision gauges. Full inspection reports are included with every shipment. We are ISO 9001:2015 certified with complete process traceability.
