Process (production process) product quality is mainly based on prevention and control; It is necessary to shift quality management from post-control to pre-control, combine prevention with post-control and implement effective quality control in every link that affects product quality, so that the whole process of product production is under strict control and the goal of stability, reliability and high quality is achieved. The specific contents of quality control in the production process are as follows: 1. Control production conditions, that is, all technical business departments (design and engineering quality) are required to provide qualified conditions for production, and operators in each process are required to effectively control the specified production conditions. Specifically, we should do the following work: 1. Ensure the correctness of the pattern template used in the production inspection site, and ensure the correctness of the work instructions and inspection documents of the whole set of process documents; 2 qualified production equipment, test equipment and process equipment; 3. Qualified raw materials, spare parts and spare parts; 4. Meet the requirements of the working environment; 5. Operators must pass training and assessment to obtain post qualifications. 2. Control important working procedures of key processes. In addition to controlling the above production conditions, the important processes of key processes should always grasp the changing trend of the processing quality of key parts to keep them in good condition. Key process Important process reference: 1. The process of forming key elements (size processing parts and technical requirements) of key parts and important parts; 2. Processes with unstable quality, repeated failures, many unqualified products and difficult process; 3. The processing cycle is long, and raw materials are expensive. Once problems occur, control points and control charts should be established according to actual needs for key processes and important processes with large value loss, and the process regulations and requirements should be compiled. At the same time, inspectors should supervise and inspect, find out the hidden dangers that may lead to unqualified products in time, and take measures to control them, so as to nip in the bud the key processes and master two links: one is to choose the applicable control method from reality, the other is to give technical guidance to operators, better control key processes and important processes, and formulate targeted process requirements and quality control measures; The key process should be determined by five methods, namely, personnel, equipment and testing instruments, process parameters, process methods and control methods; The key processes should be controlled by three inspections and three special processes, which is the key to determine the internal quality of products, and it is not easy to find them intuitively, such as glue pressing (hot pressing, high-frequency pressing, vacuum pressing, cold pressing, solid wood splicing and other gluing operations). This aspect mainly controls the process parameters and environmental conditions that affect the parameter fluctuation. Requirements: 1. Prepare quality control procedures and technical documents for special processes. 2. Improve the quality control standards of special processes, keep up with the international advanced level, organize research on weak links, focus on special process detection methods, and improve detection accuracy and ability; 3. Equipment, instruments and meters used in special processes must be inspected regularly according to relevant regulations, and unqualified ones shall not be used (hygrometers shall be submitted for inspection in time); 4. Strengthen the training and assessment of inspectors of special process operators, and strive to improve their technical quality. Unqualified persons cannot operate the four quality assurance technology in their posts. Effectively implement the four-product guarantee technology. According to the quality standards and inspection procedures, inspect the quality of raw materials, outsourced parts, products in process and finished products, and strictly control them, so that unqualified materials will not be put into production, unqualified parts will not be assembled, and unqualified finished products will not leave the factory. To do a good job in quality inspection, it is necessary to correctly define the inspection scope and set up inspection procedures, reasonably choose inspection methods, and implement the first three inspection systems (self-inspection, mutual inspection and special inspection) to prevent mass quality problems. 5. Control the technical documents, establish a technical document change system, ensure the correctness of all kinds of technical data used by the production inspection site and various functional departments, and ensure that the relevant parts involved in the change are coordinated. Invalid technical documents of drawings will be abolished from all points of use in time. 6. Scientific batch management should be carried out for products from feeding and processing to final assembly. A process flow card should be established to ensure that the part batch identification is clear and the processing time, operator and inspector records are complete, so as to ensure the traceability of product quality. 7. All links in the assembly process should be strictly controlled to ensure the assembly quality of products and the reliability of work. In order to find problems in time and prevent quality accidents, the assembly conditions should be: 1. Keep the work site clean and the temperature and humidity meet the requirements; 2. Workers' inspectors understand the product structure and master the assembly process regulations and technical requirements; 3. The inspectors can only operate at their posts after passing the examination; 4. The workshop should identify the processes that have a significant impact on the assembly quality (such as product performance, safety and reliability) and those with complex processes as the key processes, and set up control points for teams or individuals who perform key processes to control the key quality of these processes; 8. Mastering quality dynamics To do a good job in quality control of product production process, we must master the current situation and dynamics of product quality, and comprehensive statistics and analysis are tools to master quality dynamics. For example, through the statistics and analysis of the unqualified rate of products, we can grasp the relevant situation in time so as to take corresponding measures and implement the quality control of the whole production process. In addition to the above aspects, we should fully rely on the masses and extensively carry out quality management group activities. Using mathematical statistics and other scientific methods to control quality, production workers and technicians have rich practical experience and are the creative source of quality control methods. Quality management departments should attach great importance to mass quality control activities, help them sum up experience, constantly improve quality control methods, strengthen the management of product quality formation process, do a good job in every production link, ensure product quality with excellent work quality, and adhere to the business philosophy of quality first and customer first. Long-term and stable production of high-quality and low-priced products, meeting people's growing material and cultural needs, and constantly improving the economic benefits of enterprises are the goals pursued by all enterprises, and also the important idea of total quality management. 9. The enterprise should train and educate the production personnel with process discipline and operation rules as the main content, and explain to the employees repeatedly why they must do this but not that. Operators must be required to keep in mind the process indicators and operating procedures and master the operating procedures skillfully. Only by passing a rigorous examination can you be employed. At the same time, you should link the work performance of each operator with personal economic income, reward and punish severely, and turn strict compliance with process discipline and operating procedures into conscious actions of operators.
