Although my country's current mold technology has improved, there is still a certain gap compared with foreign countries. Let me take a look at the main gaps. 1. Contradiction between production and demand: 　 　 The continuous improvement of the level of industrial development, the acceleration of industrial product renewal, and the higher and higher requirements for molds. Although the mold industry has developed greatly since the reform and opening up, both quantity and quality cannot be satisfied. The demand of the domestic market can only reach about 70% at present.

The reasons for the outstanding contradiction between production and demand are that the first is specialization and low standardization. Except for a small number of standard parts purchased, most of the workload needs to be completed by the mold factory. The constraints on the management system of processing enterprises have resulted in a long mold manufacturing cycle that cannot meet market requirements. The second is the backward design and process technology, such as the uncommon use of mold CAD/CAM technology, and the low rate of numerical control of processing equipment, which also results in low mold production efficiency and long cycle times. In short, it is a hindrance to the development of the electromechanical and light industry industries.　　 Two, product structure, enterprise structure, etc.: 　　 molds are divided into ten categories according to national standards, among which stamping molds and plastic molds account for the main part of the mold consumption. According to output value statistics, China currently accounts for 50%-60% of stamping and 25-30% of plastic molds. Advanced foreign countries attach great importance to the development of plastic molds. The proportion of plastic molds generally accounts for 30%-40% of domestic molds, which are large, precise and complex. , Long-life molds are relatively low, about 20%, and more than 50% abroad. The structure of my country's mold manufacturing enterprises is unreasonable. The main mold production capacity is concentrated in the mold branch (or workshop) of each OEM. The mold commercialization rate is low, and the proportion of molds produced and used by themselves is as high as 70%. Overseas, more than 70% are commercialized.　　3. Product level: 　　 measures the mold product level, mainly including the manufacturing precision and surface roughness of mold processing, the complexity of processing molds, the service life of molds and the manufacturing cycle. There is still a big gap in the level of domestic and foreign mold products. Fourth, the level of process equipment: 　　https://www.pet-mould.com/product/blow-mould/

China's machine tool industry has been able to provide a relatively complete set of high-precision mold processing equipment, such as: machining centers, CNC milling machines, CNC profiling milling machines, electric machining machines, coordinate grinders, smooth grinding machines, three-coordinates Measuring machine etc. However, in terms of machining and positioning accuracy, machining surface roughness, machine rigidity, stability, reliability, and matching of tools and accessories, there is still a big gap compared with foreign countries.　　 Here, I have counted the gaps between my country's mold technology and foreign countries, and hope that various companies can learn from and absorb foreign experience, work hard to develop technology, and make contributions to my country's mold production.
