Especially for the control of wire and cable manufacturing process, it is better to find the problem as soon as possible, because the manufacturing process is superimposed, and it is difficult to solve the problem until it is found and processed, which will also cause unnecessary losses to the enterprise. The quality inspection of the wire and cable production process is carried out in accordance with the requirements of the production plan, process instructions and operating procedures. There are various forms of inspection. This article focuses on the product process inspection classified by the production process, that is, the first article inspection, itinerant Inspection, completion inspection.
The first article inspection should be very important, because it can find problems at the beginning, solve problems, develop preventive measures, and prevent batch non-conformities, which plays a very important role. For example, a worker turns on the extruder in the morning, and when the heating temperature is reached, production starts. Then this is the first inspection to check whether the temperature of the extruder has reached the specified temperature, whether the gloss of the discharged material, whether there are rubber particles, non-plasticized particles, etc., if there is, it indicates that the holding time is not enough. When starting up, quality problems are bound to occur. When substandard products are found, they should be analyzed and preventive measures should be formulated. For the first article inspection, self-inspection, mutual inspection, and special inspection can be introduced. For the above three inspections, I think that the self-inspection is that the operator inspection has a higher chance of finding hidden dangers than the special inspection. There are many production machines in the workshop, and it is impossible for each unit. There are special inspections at start-up. At this time, the self-inspection should play its important role, which is also the key point to prevent substandard products from flowing into the next process. But often the opposite is true. Inspections depend on the inspectors. This is also a bad idea. Quality requires full participation, not the obligation of that person, but everyone's responsibility. The improvement of quality is based on the standard. Based on the degree of understanding and the flexibility of application, everyone can be a quality inspector. Change the concept and the problem will be solved.
