We implement quality control in accordance with the ISO 9001 standard, with the core objective of establishing a sustainable, preventive quality management system.
I. Foundation of the System: Standardized Processes
• Shared Responsibility: Define quality responsibilities for all positions — from management to machine operators.
• Document Control: Standardize and document process parameters and inspection criteria.
• Supply Chain Management: Establish supplier evaluation procedures; mandatory incoming material inspections (e.g., spectrographic chemical composition analysis).
II. Process Control: Three Key Lines of Defense
1. First Article Inspection (FAI)
• Inspect ≥6 pieces from the first production batch of each shift.
• Focus on detecting burrs, porosity, and dimensional tolerances.
2. Bi-Hourly Patrol Inspection
• Inspect ≥10 randomly selected pieces per production line every two hours.
• Monitor real-time process parameters such as mold temperature (180–220 °C).
3. Self-Defense Mechanism
• Operators perform self-inspection every 20 pieces.
• Cross-inspection between upstream and downstream processes to prevent defect leakage.
III. Continuous Improvement Loop
• Root Cause Analysis: Use fishbone diagrams to trace defects back to their root causes.
• Data-Driven Action: Track defect frequency by type and use Pareto charts to identify the top three recurring issues.
• Preventive Upgrades: Implement an ongoing cycle of internal audits → corrective actions → management reviews.
