Metrology Infrastructure, Zeiss CMM & Material Traceability
Real precision requires verifiable inspection physics. Our temperature-stabilized metrology laboratory guarantees that delivered components strictly adhere to your 2D drawings and GD&T specifications.
Zeiss CMM Coordinate Metrology
Climate-controlled inspection room maintained at 20°C ± 0.5°C. Calibrated Zeiss Coordinate Measuring Machines (CMM) with continuous scanning ruby probes execute automated multi-point GD&T checks, true position calculations, and complete First Article Inspection Reports (FAIR).
100% Native Heat-Lot MTR Traceability
Every alloy block (6061-T651, 7075-T651, Ti-6Al-4V, 316L, 17-4PH) is sourced with original Mill Test Reports (MTR) verifying chemical composition and mechanical tensile properties. Secondary incoming material hardness testing (Rockwell HRC and Brinell HBW) ensures zero counterfeit stock.

Frequently Asked Questions: Multi-Industry Precision Manufacturing
Key engineering, tolerance, and procedural insights for hardware designers, mechanical engineers, and procurement directors evaluating AS Prototypes.
We implement a pragmatic dual-track tolerance methodology. For structural features, clearance pockets, and cosmetic outer surfaces, we standardise on ISO 2768-m (±0.05 to ±0.10 mm) to maximise machining feed rates and minimise cycle times. We reserve tight tolerances (ISO H7/h6 fits, ±0.005 mm on wire EDM and surface grinding) exclusively for functional bearing journals, seal grooves, and optical alignments. This targeted approach prevents over-tolerancing and saves our clients 30% to 50% in unnecessary manufacturing costs.
Every production order includes a standard Certificate of Conformance (CoC) and raw material Mill Test Reports (MTR) confirming chemical composition and mechanical hardness. Upon request during RFQ submission, our quality engineering lab provides comprehensive First Article Inspection Reports (FAIR) based on Zeiss CMM dimensional scans, surface roughness (Ra) profilometry charts, helium mass spectrometry vacuum leak test certifications (< 1×10^-10 mbar·l/s), and plating thickness measurements.
Ex-factory lead times depend on geometry and surface finishes. Standard 3-axis prototype components in natural finish ship in 4–8 business days. Complex 5-axis aerospace titanium components with Type III hard anodizing or ASTM A967 passivation ship in 7–12 business days. Bridge injection tooling and vacuum casting typically require 18–35 business days. All production schedules are strictly segregated from international air freight transit (DHL/FedEx/UPS, 3–5 business days) to ensure clear accountability.
Intellectual property security is fundamental to our enterprise partnerships. We execute bilateral non-disclosure agreements (NDAs) prior to receiving proprietary CAD files. Customer data is stored on encrypted, access-restricted engineering servers with zero external internet indexing. All scrap materials and machining chips from proprietary projects are destroyed in-house, and parts are shipped under neutral export packaging with custom English labelling to protect your commercial confidentiality.
