Quality Control Process
Quality Control Flow
Material Inspection
Raw Steel QC
In-Process QC
Manufacturing
Final Inspection
Pre-Shipment
Traceability
Batch Tracking
1. Material Inspection
Incoming chromium alloy steel (65Mn, 68CrNiMo) undergoes comprehensive inspection:
- Chemical composition analysis (spectroscopy)
- Hardness testing (HRC measurement)
- Dimensional checks (thickness, width tolerances)
- Surface quality inspection
- Material certificate verification (mill test certificates)
2. In-Process Quality Control
Continuous monitoring during manufacturing:
- Pitch measurement (drive link spacing accuracy)
- Gauge verification (drive link thickness)
- Cutter geometry inspection (chisel vs. semi-chisel profile)
- Heat treatment verification (hardness, tempering curves)
- Chrome plating thickness (for premium models)
- Assembly integrity checks
3. Final Inspection
Pre-shipment quality verification:
- Dimensional accuracy (pitch, gauge, drive link count)
- Surface finish and deburring quality
- Assembly integrity (rivet integrity, link connection)
- Batch sampling per AQL (Acceptable Quality Level) standards
- Visual inspection for defects
- Packaging integrity and labeling accuracy
4. Material Traceability
Complete traceability from raw material to finished product:
- Batch tracking system (raw steel lot numbers)
- Production batch identification
- Lot numbers on packaging and documentation
- Material certificate retention (5+ years)
- Quality records database for audit purposes
