In modern manufacturing industry, injection molding accessories as a key part in the production process, its quality is directly related to the performance and reliability of the final product. In order to ensure that injection molding accessories can meet the high standards required, manufacturers must implement strict quality control measures. This paper will discuss the quality control standards and methods of injection molding accessories from the aspects of material testing, dimensional precision control, surface treatment, etc.

Material testing
The quality of injection molding accessories depends on the choice of their raw materials. Quality materials are the basis for ensuring the durability and efficiency of accessories. Therefore, for injection molding accessories, material testing is a crucial step. Before raw materials enter the production line, a series of rigorous testing procedures such as chemical composition analysis, hardness testing, microstructure inspection are required to ensure that they meet the established specifications. In addition, for some special purpose injection molding accessories, it may also be necessary to conduct more professional material performance tests, such as corrosion resistance, wear resistance, etc.

Dimensional accuracy control
Dimensional accuracy is one of the important indexes to measure the quality of injection molding accessories. The high-precision size not only ensures the consistency of the mold, but also improves the yield of the injection parts. To this end, manufacturers must use advanced measurement technology and precision equipment in the production process to monitor the dimensional deviation of each process. For example, non-contact measurements using a coordinate measuring machine (CMM) or a laser scanner enable fast and accurate dimensional inspection of injection molding accessories with complex shapes. In addition, the establishment of a strict process control system is also the key to ensure dimensional accuracy, which includes regular calibration of the machine, technical training of the operator and continuous monitoring of the production environment.

Surface treatment
The surface quality of injection molding accessories is also critical. Good surface finish can not only improve the service life of the mold, but also reduce the defects of plastic products. Common surface treatment techniques are polishing, chrome plating, nitriding and so on. Polishing can significantly improve the roughness of the die surface and make it more smooth; Chromium plating can enhance the surface hardness and corrosion resistance, suitable for applications requiring high wear resistance; Nitriding treatment is to improve the surface hardness without changing the size of the part, and maintain the toughness of the heart, which is suitable for bearing large impact loads.

Integrated quality management system
In addition to the above specific testing and control means, the establishment of a comprehensive quality management system is also an indispensable part of ensuring the quality of injection molding accessories. This system should cover the entire process from raw material procurement to finished product shipment, and strictly implement internationally recognized quality management standards such as ISO9001. Through continuous improvement of production process and technology, strengthen staff training and assessment, and carry out customer satisfaction surveys and other activities, continue to improve the overall quality of injection molding accessories.

To sum up, through the implementation of strict quality control measures in many aspects such as material testing, dimensional accuracy control and surface treatment of injection molding accessories, manufacturers can not only produce high-quality products, but also win the trust and support of customers. With the development of science and technology and changes in market demand, the future of injection molding accessories will face more challenges, but as long as we adhere to the high standard of quality control concept.
