What Is the Role of Process Control in Manufacturing?

Production process control In order to ensure that the production process is in a controlled state, it analyzes, diagnoses and monitors the operating techniques and production processes adopted in the production, installation and service processes that directly or indirectly affect product quality.

Production process control

: Production process control function:

Its role is to systematically arrange the quality control of the production process, to focus on the factors that directly or indirectly affect the quality of the process, and to formulate and implement a control plan to ensure the quality of the process.

: Main contents of production process control :

Material control, traceability and identification. The type, number and requirements of materials and parts required during the production process shall be specified to ensure the quality of the process materials and maintain the suitability and suitability of the products in the process; identify the materials in the process to ensure the identification and verification of materials Traceability of status.

Equipment control and maintenance. Make corresponding provisions for equipment tools, measuring instruments, etc. that affect product quality characteristics, and verify their accuracy before use, store and protect reasonably between two uses, and regularly verify and recalibrate; develop preventive equipment maintenance plans, Ensure equipment accuracy and production capacity to ensure continuous process capability.

Control and management of key production processes. Focus on the product characteristics that are not easy to measure, focus on the special skills required for the maintenance and operation of the equipment, and the special processes; improve and correct the deficiencies in the process in a timely manner, and monitor, control and verify the process parameters at appropriate frequencies during the production process In order to know whether all equipment and operators can meet the needs of product quality.

Document control. Ensure that process planning requirements are fulfilled and that process-related documents used in the process are valid versions.

Process change control. Ensure the correctness of the process change and its implementation, clearly specify the responsibilities and permissions for the change, evaluate the product after the change, and verify the expected effect of the change.

Control of verification status. Use appropriate methods to identify the verification status of the process, identify unverified, qualified or unqualified products through the identification, and identify the responsibility for verification through the identification.

Control of non-conforming products. Develop and implement non-conforming product control procedures, identify non-conforming products in a timely manner, clearly identify and store the non-conforming products, determine the treatment methods of non-conforming products and supervise to prevent customers from receiving non-conforming products and non-conforming products Unintended use, to avoid unnecessary costs for further processing of non-conforming products.
