Lot Metrology & Traceability

Spectrographic alloy testing verifies mill test reports against international standards before primary machining commences.

CMM coordinate measuring machine verification confirms multi-axis geometrical tolerances against client engineering drawings.

Batch-level tracking links individual component serial numbers directly to raw material melt logs and heat treatment records.

Enforcement Policy

Out-of-tolerance components face immediate rejection prior to final packaging. We maintain contractual accountability across every tier of the Taiwanese supply chain.
