"Product quality control is a headache for every enterprise." Quality control is a systematic project with its own rules and unique control methods. If you do not master the correct quality control methods, it will be difficult to control the quality of the product, and even some unexpected quality problems will occur, causing great economic losses to the enterprise. But quality control is by no means easy, and this is where the competitiveness of an enterprise lies.
A technical chief engineer who has been working for decades has summarized the following 6 concise opinions on quality control, hoping to help everyone 1 Do not easily determine the process, and do not easily change the determined process
1) If the product has quality problems, find the root cause, main factors or main manifestations of the problem; 2) Before the problem is clarified, easily changing the process actually conceals the real cause and problem. 2 Process control must have a strong sense of quantification and traceability
1) Quality depends on many factors, and do not ignore any details; 2) Any details should be controlled and recorded with data as much as possible; 3) Failure to control and trace process details will mislead the formulation of corrective and preventive measures. 3. Be patient when solving problems
1) Don't be impetuous and hope to achieve success in one go; 2) Don't ignore abnormal situations because they seem to have nothing to do with the problem being solved; 3) Don't take no action when you can't find the cause and pattern, you can control and standardize the influencing factors of the analysis; 4) Review some of the experiences and patterns that were previously tested and summarized; 5) Once you find some experiences and patterns, go deeper and elevate them to theory, even if it costs more; 6) You should know that "a thousand-mile embankment is destroyed by an ant hole" and "Yugong moves mountains".
4. Establish a preventive mindset
1) The highest level of quality management is prevention, not how to save it after a problem occurs; 2) There must be signs before any quality problem occurs, it depends on whether you have methods, means and experience to monitor and identify; 3) The same quality problem should be highly valued when it occurs for the second time; 4) The daily process and result data should be sorted out with certain tools, and the patterns and changing trends should be found from the sorted results. These patterns and trends need to be constantly revised; 5) Before processing the product, each control factor should be as consistent as possible.
5Quality control must have management thinking
1) Don't expect to rely directly on process engineers to achieve stable product quality; 2) Product quality is manufactured. If you don't manage the direct manufacturers, the quality will never be stable; 3) Therefore, you must observe, pay attention to and study the performance and status of the direct manufacturers of the products, and manage and mobilize these performances and status; 4) If the performance and status of the direct manufacturers of the products are not controlled, once a quality problem occurs, you will never analyze the accurate cause; 5) Don't think that if the process control requirements stipulated in our current process discipline are met, the product quality will definitely be fine; 6) Therefore, our process control requirements must be continuously improved, and people must also be managed well.
6. Listen to opinions and suggestions more often. 1) Don't think that others' opinions are worthless because they don't know the actual situation and can't solve the problem at once; 2) But they, especially the direct manufacturers of the products, can give us a lot of tips and reminders; 3) If you can solve the problem, you don't need to listen to anyone's opinions and suggestions; but when you can't figure it out, it is recommended that you should listen to anyone's opinions and suggestions, and try and experiment, regardless of whether you agree or not; 4) The thinking of quality management often touches the forefront of science and technology. Even a casual sentence or a complaint may guide or hint at a major technological innovation direction, so professional technicians should pay attention to details and be good at capturing details.
