Wire and cable production process quality control inspection

The understanding of the test according to the relevant standards is: through the use of observations and judgments, appropriate combined measurements, and comprehensive evaluations of the tests. The purpose of the inspection The author of this paper believes that it is to satisfy the customer's expectation of product quality, and any process planning should be conducted around the customer. When applying the process approach in the quality management system, the importance of four aspects is emphasized. 1. Understand and meet requirements, 2. Need to consider the process from the perspective of value added, 3. Obtain results of process performance and effectiveness, 4. On the basis of objective measurement, continuous improvement process. It can be seen how important process control is. Especially for the wire and cable manufacturing process control, the more timely the better the problem is discovered, because the manufacturing process is superimposed, and the reprocessing of the finished product is found to be quite difficult and will cause unnecessary losses to the company.

The quality inspection of wire and cable production process is carried out according to the requirements of the production plan, process instructions and operating procedures. The forms of inspection are various. This paper focuses on the product process inspection classified according to the production process, ie, the first inspection and inspection. Inspection, completion inspection.

one. The first inspection of the first inspection should be very important, because at the beginning it is very important to be able to find problems, solve problems, formulate preventive measures and prevent batch unqualified. A worker opened the extruder in the morning, and when the warming temperature reached, production began. Then it belongs to the first inspection, to check whether the temperature of the extruder has reached the specified temperature, from the gloss of the discharged material, with or without rubber particles, if not, indicating that the holding time is not enough. When starting up, it will inevitably cause quality problems. When unsatisfactory products are found, they should be analyzed and preventive measures should be formulated. For the first inspection, self inspection, mutual inspection, and special inspection can be introduced. For the above three types of inspections, I believe that the self inspection is a higher chance of the operator inspection than the special inspection, and there are many workshop production machines. The special inspections are all in place. At this time, self-inspection should play an important role in its position. This is also a key to avoid the inconvenience of goods entering the next process. But often the facts are contrary to the fact that inspections rely on the inspection personnel. This is also a bad idea. Quality is the need for full participation. It is not the duty of that person. It is the responsibility of everyone. The improvement of quality is based on standards. Based on the degree of understanding and the flexibility of application, everyone can be a quality inspector. Changing the concept will solve the problem.

Second, the roving inspection The roving inspection is the full inspection of the quality inspector on the workshop process. It is considered that the frequency of the important processes and materials can be inspected. The occurrence of the problem is instantaneous. Example: When worker A is doing the normal production of the stranded wire, the inspector measures the outside diameter of the conductor and finds that the outside diameter is reduced. Then the inspector should be familiar with the process specification and the time has come to play. If the outside diameter becomes smaller and the resistance exceeds the standard, the worker should be stopped. The inspection is due to the small diameter of the monofilament, or to the equipment, because the first part inspection meets the requirements. Find out the reasons, sort statistics, and improve. Therefore, it is still necessary to supervise the operating personnel to become familiar with the process regulations and check the implementation. If the inspection is not conducted in time, it will also cause unqualified batches.

3. Completion inspection Completion inspection is a form of inspection for the completion of a semi-finished product. It verifies whether it complies with the requirements. For example: The machine platform produces a 10 kV overhead line. Then the completion inspection must first look at the terminal conductor root. Number, insulation thickness, thinnest point, average thickness, finish. Analyze quality by measuring and visual inspection.

Quality is an eternal topic. As quality personnel, we must consider how to improve and continuously improve the company's unique quality control methods through the use of total quality management methods. Quality awareness requires the execution of all employees and the importance of full participation. Strengthen process control, continue to achieve customer satisfaction, and achieve the goal of healthy growth of the company.
