We have established a quality control system within the company according to the PDCA cycle optimization method, and established a chain-type quality management process of "raw material procurement-production-finished product-packaging-warehousing-logistics and transportation". The specific management points are as follows:
1. Raw material procurement: establish supplier screening standards, sign a "Quality Assurance Agreement", and clarify the performance indicators of each raw material and the penalty mechanism for breach of contract;
2. Product production: standardize process production and equipment management, establish SOP, monitor and record in real time; implement TPM (Total Productive Maintenance) for production equipment, calibrate core equipment monthly to reduce failure rate;
3. Finished product quality inspection: Establish finished product physical and chemical properties test system standards to achieve a yield rate of 99%;
4. Packaging specifications: follow standard packaging procedures to prevent product damage and conduct secondary quality inspection;
5. Warehousing standards: Warehouses are divided into zones for management and temperature and humidity are monitored in real time;
6. Logistics and transportation: Standardize international logistics packing standards or implement according to customer standards, select long-term high-quality logistics companies for cooperation to prevent product damage during transportation.
