How to control the quality of die casting products?
Product quality control has always been the top priority of factory production. Especially for some precision aluminum die-casting series products, if the product quality is not up to standard, it will be rebuilt and the factory funds will be lost innocently.
1. Do not easily determine the process, and do not easily change the determined process
(1) To find the root cause, main factor or main manifestation of the problem.
(2) Easily changing the process actually hides the real cause and problem.
2. Process control must have a strong sense of quantification and traceability
(1) Casting is not affected by that factor, 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. Problem solving must be patient
(1) Don't expect too much to eat a fat man in one go.
(2) Don't 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) Re-review and review some of the experiences and rules from previous experiments and summaries.
(5) Once some experience and laws are discovered, 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 in one cave", and also that "the foolish man moves mountains".
Fourth, to establish the thinking of prevention
(1) The highest state of quality management is prevention, not how to save after a problem occurs.
(2) Before any quality problems appear, there must be signs, it depends on whether you have the methods, means and experience to monitor and identify them.
(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 casting the product.
Five, quality control must have management thinking
(1) Don't hope to directly rely on craftsmen to achieve the stability of product quality.
(2) The quality of the product 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 controlled, once there is a quality problem, you will never analyze the inaccurate cause.
(5) Don't think that the process control requirements stipulated in our current process discipline are met, and the product quality is absolutely fine.
(6) Therefore, our process control requirements should be continuously improved, and at the same time, people should be managed well.
Six, to 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 have 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 make up your mind, it is suggested that anyone's opinions and suggestions should be listened to, and should be tried and tested, whether you like it or not. agree
(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. Therefore, professional and technical personnel should pay attention to details and be good at capturing them. .
