How to control the quality 1 article in the production process;
① Material control, traceability and identification. The types, quantities and requirements of materials and parts needed in the production process should be specified accordingly to ensure the quality of materials in the process and maintain the applicability and suitability of products in the process; Identify the materials in the process to ensure the traceability of material identification and verification status.
② Control and maintenance of equipment. Make corresponding regulations on equipment, tools and measuring instruments that affect the quality characteristics of products, verify their accuracy before use, store and protect them reasonably between uses, and conduct regular verification and recalibration; Make preventive equipment maintenance plan to ensure the accuracy and production capacity of equipment to ensure continuous process capability.
③ Control and management of key production processes. Pay attention to the product characteristics that are difficult to measure, and control the special skills and processes required for the maintenance and operation of related equipment; Timely improve and correct the deficiencies in the process, and monitor, control and verify the process parameters at an appropriate frequency in the production process, so as to know whether all equipment and operators can meet the needs of product quality.
④ File control. Ensure that the requirements of process planning are realized, and ensure that the process-related documents used in the process are valid versions.
⑤ Process change control. Ensure the correctness and implementation of process changes, clarify the responsibilities and authority of changes, evaluate the changed products, and verify the expected effect of changes.
⑥ Control of verification status. Use appropriate methods to identify the verification status of the process, distinguish unverified, qualified or unqualified products by identification, and determine the responsibility for verification by identification.
⑦ Control of nonconforming products. Formulate and implement nonconforming product control procedures, find nonconforming products in time, clearly identify nonconforming products and store them in isolation, decide on the treatment methods of nonconforming products and supervise them, so as to prevent customers from receiving nonconforming products and their unexpected use, and avoid unnecessary expenses caused by further processing nonconforming products.
Control method:
① Formulate and implement special quality control procedures;
② Strengthen inspection and supervision;
(3) Fill in quality records in detail, define responsibilities and ensure traceability;
④ Strictly control the disposal of unqualified products;
⑤ Strengthen equipment maintenance;
⑥ Use statistical control methods to control the production process, such as control charts, statistical sampling procedures and schemes.
How to control quality in the production process Part II Step 1: Cultivate three kinds of consciousness.
As a quality training, the most talked about is what quality is and how to do it well. Often you are thirsty on the stage and the students want to sleep. After the training, the students whispered to each other and finally summed up a sentence: good is good, but it is not practical for us! As a coach, I am half dead again.
The first is the consciousness of self-examination. The quality of products is made, not tested. The secret of production quality control is: let everyone make their own products. Employees are required to conduct self-inspection on the products they produce, and only the products they think are qualified can flow to the next working procedure or workshop. Non-conforming products found in self-inspection shall be identified by themselves and placed separately.
The second is mutual inspection awareness. For the products flowing from the previous process or workshop, employees must not suddenly pull them down without looking at them. Production can only be carried out after inspection, and the quality problems found in the previous process or workshop can be fed back in time. Resolutely do not do defective products, do not accept defective products, and do not let go of defective products.
The third is the awareness of special inspection. After self-inspection and mutual inspection, the production supervisor can instill in the full-time inspectors that employees are also doing self-inspection and special inspection at the same time of production. As full-time inspectors, they should have a strong sense of quality control. If the full-time inspector is a subordinate of your department, it is best to communicate; If he is not from your department, he will also accept your teaching!
Step 2: Strictly follow the process control.
For friends who talk to me about consequentialism, I will ask them, if there is no process, where will there be results? When they are dumbfounded, I will tell them that I pay attention to the process. Without a good process, it is difficult to have a good result! As for quality control, I think quality can only be controlled by following process control; Therefore, when teaching a friend, I asked him to keep up with the process control.
The first is the first inspection control. Before the product goes online, the team leader, quality inspector and employees must be required to carefully verify the materials to be put into production; Confirm whether the performance of the equipment used is stable and intact. Then three products are produced in small batches to confirm whether the products are qualified. Start production after passing the test. If you are unqualified, you must find the reason, and you can't mass-produce until you are qualified.
The second is inspection control. In the production process, managers and quality inspectors should conduct spot checks on products, and pay 80% attention to weak links in production, such as novice employees, key equipment and key positions.
The third is the final inspection control. When closing the line, we should focus on controlling the final product, and often the employees' mentality is impatient at this time. I once touched something, and now I'm afraid to think of it. When an employee was about to leave work, he still lacked a product to pack, so he found a nonconforming product, had it repaired by someone, and packed it directly without passing the inspection personnel. Immediately corrected by the team leader, the product has serious quality defects. What's more, when the products are closed, there are still some products waiting to be repaired, so the faster the work is completed, the stricter the control!
Step 3: Add two more weapons.
Quality control in the production process is either rising or falling. In order to achieve the "long-term stability" of quality management, managers must carry "open knife" and "hidden arrow" with them.
The first weapon is the "Ming Dow"-"Three Analyses and Three Failures" activity. As the saying goes, a knife is easy to hide, but it also depends on who is using it and what knife is used. If you are a martial arts master with a wooden knife in your hand, I don't think anyone can hide: but if you are a person who has never practiced kung fu and has a bright treasure knife in your hand, do you dare to hide? The weapon I taught is a "Ming Dao" with a knife spectrum. At the morning meeting every day, we should analyze the quality problems that appeared and encountered in yesterday's production, and deeply analyze the harmfulness of these quality problems, so that everyone can fully realize that once unqualified products leave the factory, they will not only have a huge negative impact on enterprises, but also harm the interests of users. Next, it is necessary to analyze the causes of these qualities, trace them back layer by layer, clarify the quality responsibility and find out the loopholes; On this basis, the measures that should be taken are analyzed and put into practice, and the deficiencies are improved in time. In the whole activity, the managers who truly "don't let go of the reasons, quality responsibilities and rectification measures" hold "Ming Dow" in one hand and strive to improve the quality a little every day.
The second weapon is "stabbing in the back"-the method of testing personnel's quality awareness. As the saying goes, the arrow is on the string, and it is impossible to prevent it. Without this "backstabbing" in quality control, how to prevent employees from being careless? The implementation process of the personnel quality awareness test method is as follows: managers look for some unqualified products with inconspicuous quality defects from time to time, write down the numbers or mark them, and mix them with a large number of similar products to see if employees can check them out in time and completely. Those employees who don't have a strong sense of quality and don't work hard often find it difficult to get high marks when they encounter such an "exam" that may be held anytime and anywhere without saying hello in advance.
How to control the quality in the production process The third part is the control of raw materials: relevant regulations should be formulated for the purchased raw materials, and the inspection results are divided into qualified products, energy supplies (degraded products) and unqualified products. And do a good job of identification, classification and placement to ensure correct use. Of course, the qualified logo should be customized by the enterprise itself.
The second is the control and maintenance of equipment and special tools that affect quality. For example, regular inspection and precision calibration of equipment, equipment, tools and special measuring instruments, and correct use methods (each enterprise has its own regulations).
The third is the control in the production process, which consists of two elements: people and equipment. First of all, we must do a good job in talent training. It is not enough to have good talents, and you can't produce good products without equipment. In addition to technology, we must also have a particularly strong sense of responsibility for talents. Equipment must be maintained in time to meet the requirements of product quality. It is necessary to clarify the equipment maintenance management system and maintenance record ledger.
It is to control the quality documents, formulate the process requirements and quality regulations of each process, and fill in the process control records in time.
Quality control of inspection department: the quality inspection department should have relevant quality management system, and the quality inspector will conduct random inspection on each working procedure from time to time, and the first inspection, patrol inspection and final inspection will be carried out for special working procedures. Finally, it is a full inspection. And fill in the relevant quality inspection records.
Pay attention to the quality control of quality inspection department. Quality inspection records can be divided into incoming inspection records, inspection records in the production process and final inspection records (the specific content is determined by the company itself).
Control of nonconforming products: how to prevent nonconforming products from reaching passengers and goods? First, each working procedure should be self-checked in time to separate the unqualified products. Quality inspectors should strengthen inspection and supervision. Fill in the quality records in detail and clarify the responsible person, which can be investigated. Unqualified products should be isolated from qualified products and placed separately. And do a good job in area identification and listing identification. Ensure that qualified products reach customers.
