How do enterprises improve product quality?

To improve the product quality is to connect several factors such as the company's man-machine material method in series in the big production process. Here is a total relationship of total scores. First, we should summarize the current product quality, and then decompose the current product quality into various production processes from raw materials to products. Then make improvements according to the current production process, then summarize the final quality of the product, and finally make a comparison between this result and the result before adjustment.

methods/steps:

1. summarize the design technical data of existing products and existing products, first find out the key quality factors of products (such as hardness of diamond tools, accuracy of measuring tools, tolerance of key dimensions of assembly parts, etc.), and then determine the yield of products now produced and what the yield is in each process. Then compare it with the reasonable qualified rate of each process in the industry.

2. After the analysis of the previous step, it is easy to find that the point where the quality can be improved lies in that process, and then analyze in detail all the links involved in production in this process, which are the problems of molds, raw materials and professional skills of personnel. Then rectify one by one according to the characteristics of each aspect. Every time a factor is rectified, make a summary immediately, and compare the previous yield to see if it has been effectively improved.

3. If the same equipment and molds (within a reasonable life) and the same factors are different because of different shifts, it can be confirmed that it is a technical problem. If it is a technical problem, a technical remedial class will be set up. If it is a problem of production attitude, a more effective reward and punishment system will be established (here, a one-to-one correspondence system between products and personnel can be established with the help of mobile phone software).

4. If the equipment, molds and personnel are the same, the product yield is different because of the different batches of raw materials or accessories provided by other suppliers, it is suggested to strengthen the inspection of raw materials and accessories, confirm the qualified rate of each purchase, add the qualified rate of products into the purchase contract, and establish an effective punishment system for suppliers.

5. If the production process and methods are different from those of other companies in the same industry, it is necessary to adjust the whole process and scheme. At this time, a lot of costs will be increased, and the cycle will be particularly long. At this time, it is necessary to evaluate the overall cost in combination with the order situation.

6. If the service life of the mold or other tooling exceeds the service life, it is recommended to replace or renovate the mold and tooling in time to ensure the qualification rate of key dimensions.

7. It is also very important to do a good job in personnel management. If the mobility of a company's personnel is beyond the normal range, and the personnel in key positions are frequently changed, then the quality of the company's products is often not stable enough. At this time, we must work hard on personnel recruitment and human resources management. A quantitative evaluation of quality and output and an effective link between bonuses are very important.
