The chief technical engineer has many years of experience and 6 suggestions for controlling product quality!

"Product quality is everyone's responsibility", high-quality products are produced, managed and controlled, not tested.

"Product quality control is a headache for every enterprise", quality control is a systematic project with its own laws and unique control methods;  cnc machining part

If you do not master the correct quality control methods, it is difficult to control the quality of products, 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 chief technical engineer for decades, the following summarizes 6 simplified 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 there is a quality problem in the product, it is necessary to find the root cause, main factor or main performance of the problem;

2) Before the problem is clarified, easily changing the process actually hides the real cause and problem.

2. Process control must have a strong sense of quantification and traceability
1) Quality depends on many factors, 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 in solving problems
1) Don't be impetuous, and hope to eat a fat man in one go;

2) Do not ignore the abnormal situation because it seems to have nothing to do with the problem to be solved;

3) Don't take action when you can't find the reason and the law, you can control and standardize the influencing factors of the analysis;

4) Review and review some of the experiences and rules from previous experiments and summaries;

5) Once some experience and laws are found, and then go deeper and turn it into a theory, even if it costs a lot of waste, it is worth it;

6) It is necessary to know that "the embankment of a thousand miles is destroyed by the ant's nest", and also know that "the foolish man moves the mountain".

4. To develop a preventive mindset
1) The highest state of quality management is prevention, not how to save after a problem occurs;

2) Before any quality problem occurs, there must be signs, it depends on whether you have the methods, means and experience to monitor and identify;

3) High attention should be paid to the second repetition of the same quality problem;

4) The daily process and result data should be sorted out with certain tools, and regularities and changing trends should be found from the sorted results. These regularities and displayed trends need to be constantly revised;

5) Each control element should be as consistent as possible before processing the product. cnc turning part

5. Quality control must have management thinking
1) Don't expect to directly rely on craftsmen to achieve product quality stability;

2) The product quality is manufactured, and the direct manufacturer is not managed, and the quality can never be stable;

3) Therefore, it is necessary to observe, pay attention to and study the performance and status of the direct manufacturer of the product, and manage and mobilize these performance and status;

4) If the performance and status of the direct manufacturer of the product are not under control, once there is a quality problem, you will always analyze the inaccurate reasons;

5) Don't think that the process control requirements stipulated in our current process discipline are met, and the product quality is absolutely no problem;

6) Therefore, our process control requirements should be continuously improved, and at the same time, people should be managed well. stamping accessories

6. Listen to more opinions and suggestions
1) Don't think that other people don't know the reality and can't solve the problem at once, and their opinions are of no value;

2) But they, especially the direct manufacturer of the product, can give us a lot of hints and reminders;

3) If you can solve this problem, you can ignore anyone's opinions and suggestions; but when you can't decide, you should listen to everyone's opinions and suggestions, and you should try and experiment, whether you agree or not. ;

4) The thinking of quality management often touches the frontier of science and technology, even a random sentence or a complaint may guide or imply a major technological innovation direction, so professional and technical personnel should pay attention to details and be good at capturing them.
