The role of quality inspection in the production process of non-woven fabrics

1. Gatekeeper function Gatekeeper is the most basic function of non-woven fabric quality inspection. It is absolutely necessary to pass quality inspections and pick out unqualified products to ensure quality. Of course, with the improvement of production technology and management, the workload of inspection can be reduced, but inspection work cannot be cancelled or replaced. In the non-woven fabric production process of our factory, through quality inspection, strict control is implemented, so that unqualified raw materials will not be put into production, unqualified semi-finished products will not be transferred, and unqualified products will not leave the factory. The real check is achieved. Check when the wall changes, eliminate the problem in the bud, and ensure that the product quality is excellent. This kind of benign practice of colleagues will also reduce and avoid the cost of failure. 2. Preventive function Quality inspection not only plays a check-point role, but also plays a preventive role. This is the difference between modern quality inspection and traditional quality inspection. Broadly speaking, whether it is manufacturing or other industries, the next process will always be the customer of the previous process. Just like the social supply and demand relationship, the company must also damage the process to ensure that any raw materials (products) made public to its customers It must be qualified. Only in this way can the production of unqualified products in the next process be effectively prevented. Therefore, from the incoming inspection of raw materials and purchased parts, the check-in inspection of the previous process, the subsequent production process and the next process production, all Played a preventive role. If it is found that the process capacity is insufficient or the production process is abnormal, technical measures shall be taken in time to improve the process capacity, eliminate the abnormal state of the production process, and prevent the occurrence of substandard products. Practice has proved that the preventive effect of this test is very effective. Furthermore, before a batch of products is put into production, when a batch of products is processed in a shift, or when the equipment is repaired or adjusted, the first article inspection must be carried out; after the official finished product is produced, it must be inspected regularly or irregularly Locally conduct patrol and spot checks on the produced products (ie, patrol inspection), and promptly take measures to solve problems found to prevent the occurrence of substandard products. 3. The role of reporting The role of reporting is also the role of information feedback. In order to enable managers at all levels to grasp the quality status in the production process in a timely manner, evaluate and analyze the effectiveness of the quality system, and make correct quality decisions, the quality inspection department must use the report of the inspection results (especially the calculated indicators) Form, feedback to leaders and relevant management departments in order to make correct evaluations and decisions. One thing to note is that in addition to the accuracy and effectiveness of the various reports, the timeliness must be ensured, because most production lines are produced continuously. If the reports are not timely, it will bring huge losses, because the samples are taken from the production line. The production line will not stop during the whole process of oxygen output. Therefore, it is necessary to select the priority and feed back the accurate inspection report to the person in charge of the production line in the shortest time to reduce the time blind spots of process inspection. 4. The role of improvement The key to giving full play to the gatekeeping and preventive role of quality inspection is that quality inspection participates in quality improvement work, which is also a concrete manifestation of Caiyu's product quality improvement activities by the quality inspection department. Quality inspection personnel implement high-quality improvement in the management of design, process, inspection and operation personnel combined, which is very necessary to accelerate the pace of quality improvement and achieve good quality management results. Improvement requires continuity. No matter what kind of improvement, we need to obtain evidence and continuously improve. With the backing of strong technical force, we must play an important role to continue the improvement, not only to meet customer requirements and make customers Satisfaction, but also to achieve the ultimate product quality, to achieve a leap in product quality, to create the maximum added value of products.
