Quality Management, Metrology & Export Compliance
Quality Assurance & Factory Verification
European and North American OEMs rely on documented, repeatable quality. Every order at Suhang Metal is governed by our ISO 9001:2015 quality management system—from raw material spectrometer verification to final CMM inspection.
4-Stage Quality Control & Metrology Workflow
Incoming Material Verification
XRF alloy analyzer verification, hardness testing (Webster/Rockwell), and EN 10204 3.1 mill certificate audit before raw stock enters production.
First Article Inspection
100% dimensional layout on the first 3–5 pieces of every setup using 3D CMM and optical projectors before authorizing mass machining or stamping.
In-Process SPC Patrol
2-hour interval floor inspections tracking critical-to-quality (CTQ) dimensions, thread Go/No-Go gauges, and surface roughness (Ra).
Final & Pre-Shipment Audit
Coating thickness (DFT) checks, ASTM B117 salt spray coupons, cosmetic inspection, and barcode/traceability labeling prior to export packing.
