QC Profile
Four-Level Quality Control Process for Hardware Processing
Level 1: Raw Material Inspection
Focus: Material composition, hardness, dimensions, surface defects.
Tools: Spectrometer, hardness tester, calipers, visual inspection.
Goal: Prevent substandard materials from entering production.
Level 2: In-Process Quality Control (First-piece + Routine Checks)
Focus:
First-piece inspection after setup/tool change.
Periodic checks of critical dimensions (e.g., holes, threads) during production.
Tools: Calipers, CMM, optical projectors, thread gauges.
Goal: Detect process deviations early and avoid batch defects.
Level 3: Semi-finished/Finished Product Full Inspection
Focus:
100% inspection of key characteristics (e.g., assembly dimensions, tolerances).
Functional tests (e.g., tensile strength, fatigue resistance).
Tools: Automated vision systems (CCD), tensile testers, salt spray chambers.
Goal: Ensure all products meet drawings and customer specifications before shipment.
Level 4: Final Outgoing Inspection & Traceability
Focus:
AQL-based sampling for packaging, labeling, and batch consistency.
Full traceability with unique batch IDs linking materials, processes, and inspections.
Tools: Barcode/RFID systems, quality traceability software, checklists.
Goal: Enable rapid response to customer feedback and continuous improvement.
Key Advantages:
Prevention-focused – Reduces risk of defective products reaching customers.
Data-driven – Uses inspection data to optimize processes (e.g., CNC tool compensation).
Adaptable – Customizable for industry standards (e.g., ISO 13485 for medical devices).
Typical applications: Automotive, aerospace, medical devices, and other high-reliability industries.
