Through the complete production process and strict quality control, key data is collected during the production process of the product, and finally a unique product serial number can be used to trace all the key information of each product production process:Material batch, supplier, operator, working place (workshop, production line,work station, etc.), processing technology (temperature, resistance, voltage, torque, etc.), processing equipment information, working time and other information.
Traceability can be divided into forward and reverse traceability.
Forward traceability: According to the product serial number, trace back from top to bottom, and trace its composition and production process information;
Reverse traceback: According to the parts or raw materials used in the product, all products using this batch of parts or raw materials are traced from bottom to top in order to narrow the scope of the recall.
