In order to control the processing accuracy of plastic thin-wall molds, it is necessary to start from the following aspects to form a complete set of quality control system.At the same time, it is necessary to continuously carry out technological innovation and improvement to improve the level of processing technology and precision.

1. Mold design: reasonable design is the key to ensure accuracy. In the design stage, the characteristics of the plastic, the cooling and heating of the mold, the shrinkage of the plastic, etc., should be fully considered. For thin-wall molds, the design should pay special attention to preventing issues such as warpage, shrinkage, and deformation.
2. Raw materials: The selection of high-quality plastic raw materials is the foundation. The purity and stability of the raw material have a great impact on the accuracy.
3. Processing equipment: The use of high-precision processing equipment is the key to ensure the accuracy of the mold. High-precision equipment such as CNC machine tools and machining centers can greatly improve the machining accuracy of molds.
4. Processing technology: reasonable processing technology is the key to ensuring accuracy. In the process of processing, factors such as thermal deformation, cooling time, and processing sequence should be considered to prevent mold deformation or internal stress.
5. Detection and measurement: During and after the processing is completed, accurate detection and measurement should be carried out to ensure that the accuracy meets the requirements, and high-precision measuring equipment and tools should be used to improve the detection accuracy.
6. Maintenance and maintenance: The mold needs to be maintained and maintained regularly. It can extend the service life of the mold and maintain its accuracy.
7. Personnel training: The skills and experience of operators have a great impact on accuracy. Operators are regularly trained to improve their skill level
