QUALITY CONTROL

Aggregate quality anomaly issues from production and the client end, conduct root cause analysis, document them, and develop corrective and preventive action plans. Establish ledgers for closed-loop rectification, conduct regular reviews and summaries to prevent the recurrence of similar quality issues.

All purchased materials must undergo sampling inspection before warehousing and can only be released for production after passing inspection. Defective materials must be uniformly isolated and sealed, strictly prohibited from entering production, with simultaneous handling of returns/exchanges, supplier rectification, and assessment, thereby controlling product quality from the source.

Each process step must strictly follow the process documentation and implement first-article inspection, patrol inspection, and final inspection mechanisms. Dedicated quality control points are established for critical processes, with dynamic monitoring of production status. In-process non-conforming products are promptly isolated, documented, and disposed of in compliance with regulations, strictly prohibiting unauthorized transfer or reuse.

Completed products undergo full-item quality inspection. Qualified products are labeled, warehoused, and documented. Non-conforming finished products are uniformly collected and managed, with rework, repair, and scrapping carried out according to regulations to ensure the quality compliance of delivered finished goods.
