Zeiss Coordinate Measuring Machine (CMM)
High-precision 3D coordinate measurement providing sub-micron scanning of stator/rotor bore profiles, slot pitch symmetry, and complex die plate geometries.
QUALITY ASSURANCE & INSPECTION
ZERO-DEFECT PRECISION: RIGOROUS QUALITY CONTROL FOR MOTOR CORES & DIES
In the world of high-speed motor lamination stamping, quality is measured in micrometers. Driven by strict IATF 16949 and ISO 9001 compliance, our comprehensive quality control system governs every stage of manufacturing—from raw electrical steel verification to final coordinate measuring machine (CMM) inspection. Guided by standardized inspection workflows, we guarantee 100% dimensional accuracy, structural integrity, and full material traceability for every tool and stamped component we deliver.
STANDARDIZED WORKFLOW
OUR END-TO-END PRODUCT INSPECTION WORKFLOW
To eliminate non-conformances before they reach your press floor, we enforce a strict multi-gate inspection process throughout production.
01
IQC - Raw Material & Component Verification
Every steel block, carbide insert, and electrical steel coil undergoes rigorous IQC upon arrival. We verify hardness, dimensions, and chemical composition against Mill Test Certificates (MTC) to prevent material flaws at the source.
02
IPQC - First Article & In-Process Inspection
During CNC milling, Sodick wire EDM, and surface grinding, our QC engineers perform 100% First Article Inspection (FAI) and routine hourly patrolling to ensure critical tolerances stay within ±0.002mm.
03
FQC - Trial Stamping & Die Assembly Audit
Prior to shipment, fully assembled progressive dies undergo trial stamping on high-speed presses. Stamped motor laminations are tested for burr heights (<0.01mm), core stacking tightness, and concentricity.
04
OQC - Pre-Shipment Audit & Anti-Rust Packaging
Final audit verifies technical compliance, surface blueing/coating quality, and documentation completeness. Dies and core stacks are treated with VCI anti-rust oil and vacuum-sealed for safe ocean transport.
METROLOGY EQUIPMENT
SUB-MICRON PRECISION VERIFIED BY ADVANCED METROLOGY
COMPLIANCE & TRACEABILITY
FULL MATERIAL TRACEABILITY & PPAP DOCUMENTATION
For automotive OEMs, industrial giants, and aerospace clients, documentation is just as critical as the physical component. Every batch of silicon steel and carbide inserts processed in our facility is assigned a unique batch code, linking directly to its original Mill Test Certificate (MTC). Upon request, we provide full Production Part Approval Process (PPAP Level 3) packages, including FAIR (First Article Inspection Reports), FMEA, control plans, and CMM dimension mapping.
