Quality control in the carton manufacturing process
Main content
The definition of quality, the meaning of quality management, the definition of macro quality management and the quality management elements are presented in detail and closely in the relevant quality monographs. Here, we just want to talk briefly about the quality of the carton factory's production process. A number of views and methods of control.
Carton factories often build internal standards based on national standards and according to actual requirements of the area or customer base. However, during the actual operation of the manufacturing process, they are often unable to fully meet customer or internal corporate standards, resulting in complaints and even returns.
First, the quality control of the manufacturing process mentioned in this article relates to the equipment, processes and materials that meet the basic requirements of the product.
1) The production quality standards and inspection methods of the process must be clear and firm.
-To achieve quality control of the production process, the operator of each quality control point must clearly keep in mind the quality standards. Mastering the quality control method to ensure the product meets the production quality
-Quality control points must have clear quality standards and internal standards of enterprises must be posted at conspicuous places of control points. For special customer quality control standards, they can be sent to the production department along with production process orders (also known as manufacturing work orders). However, for new orders, quality standards must be set in writing. The requirements of this standard should be clearly and transparently described. When production departments receive written standards, they must be binding and stored. To continue using in subsequent production. New orders may be marked with special requests. But there are general requirements
-After the quality point of the control point is clear, the operator of each quality control point must implement the quality control standard, and at the same time be proficient in using inspection tools and inspection methods to determine product quality at this control point. It should be noted here that not all quality control points have national standards, but businesses must develop quality standards and testing methods for quality control points.
For example, two-layer corrugated paper produced by corrugated machines has shape, height, adhesion, glue quantity, etc., some have quantitative standards and some cannot offer quantitative standards at production sites, but they can be based on real-world experience, using visual inspection methods or corporate inspection tools to formulate corresponding test standards and methods.
-Other examples, the printing of carton boxes stipulates that "the printing must be clear, not frayed and the printing pressure must be moderate." What exactly is "clear"? What is considered "not frayed" and "moderate printing pressure"? There is no quantitative requirement in the standard, but in actual operation, corresponding quality standards can also be formulated. For example, regarding the printing pressure requirements, "there must be no visible indentations after printing the text, or a clear indent when touched by hand, when printing 40 to 60 million, the batch is not. to show signs of adhesion.
2) All employees participate in self-inspection and mutual inspection
-All employees participate in quality control of the production process and set up self-inspection and inspection systems. For operators at each quality control point, especially those in charge of administration, they must keep in mind the quality standards of the quality control points and must master the methods of quality control detection. amount to meet writing, memorization and application requirements. When producing special order products, check customer standards and strictly implement mutual inspection and self-inspection systems. At the same time, it is necessary to clarify who is responsible for the quality control point and develop a corresponding evaluation system for the person in charge and performance.
3) Repair and maintenance of equipment
-In carton manufacturing enterprises, the role of equipment repair and maintenance is only considered to be a guarantee for normal production. In terms of thinking, there is not much involved in product quality control. , but this is an indispensable factor to control the quality of the production process. By maximizing device capabilities, reducing device errors (such as stopping errors and quality errors), improving equipment performance (quantitative and qualitative performance), by improving the safety, hygiene and environment, we can contribute to ensure product quality, improve efficiency and reduce costs.
4) Check the process and handle the defective product
- The worker is the manufacturer of the product and the first to ensure the quality of the product, the worker is responsible for conducting the self-inspection according to the quality requirements of the product, storing the self-test results ( and unqualified products) according to regulations and set up inspection documents. For defective products that occur during production, the types of defective products should be distinguished, divided between those repairable and non-repairable products, and different handling methods implemented for different products. different products. In carton manufacturing enterprises, due to the large volume and lots of products, it is difficult to identify a small number of individual defective products, but the defective product lot must be verified and confirmed, and finally treated. logical way.
5) Repair and prevention
- In recent years, businesses have been in the production phase, Although improved management and technology processes continue to increase, some quality problems due to technical issues are declining. However, quality issues due to operator negligence have not been eliminated. For example, when a production line staff converts corrugated paper of different weight, due to the unadjusted pressure in the dryer section, which causes the wave to be forced, the printing error on the printer, etc., results in Defective products, broken and even lead to customer complaints. Although not much, but today, with increasingly fierce market competition, how to solve this problem has become an important point of quality management activities in the production process. export. Existing businesses often deal with the traditional way of improving people's sense of responsibility and attention. Practice has proved that this method is limited, because the operator can only reduce errors but not eliminate errors. Therefore, to solve this problem, we should not only rely on human responsibility and attention, but also on anti-error equipment, tools and methods, trying to minimize human error. , or errors can be detected and fixed immediately. Use automatic quality testing equipment to find out quality problems in carton manufacturing process.
- The investment in modern packaging machinery and equipment saves time, manpower and reduces errors in the production process. In Vietnam, when customers need to solve the above problems, please contact Viet Dat Co., Ltd. - an expert in packaging equipment production.
