50+ Engineering Alloys & Plastics — By Grade
Material call-outs by exact grade. Mill test certificates (MTC) and traceability are provided on request, standard for aerospace and RF programs.
Functional & Cosmetic Surface Treatments
Post-process finishing managed in-house or through long-term certified partners with full inspection sign-off.
Three Tolerance Tiers — Quoted Against ISO Standards
Every job is binned into one of three tolerance tiers during DFM review. Tighter limits drive inspection method and lead-time.
- ISO 2768-mK general tolerance
- Inspected with calipers & micrometers
- Standard lead time
- ISO 2768-fH fine tolerance
- CMM verification on key dims
- +2–3 day inspection allowance
- Zeiss CMM full report (MPE 1.9μm)
- Profilometer Ra verification
- Climate-controlled (20±1℃) lab
From Drawing to First Article — Engineered, Not Just Quoted
Every project is reviewed by a manufacturing engineer before quoting. We flag tolerance risk, material substitution opportunities, and cost-down ideas in writing.
Prototype to Mid-Volume Production — Quoted in Hours
Capacity sized for prototype runs and 50,000-piece annual programs alike. Lead-times below assume DFM-approved drawings.
