For more than 10 years, especially since the eighth five year plan, the relevant ministries and commissions of the state have organized relevant material research institutes, colleges and universities and iron and steel enterprises to research, develop and promote a series of special steel grades for molds, special cemented carbide for molds and other special tools and auxiliary materials for mold processing. However, due to the unstable quality of materials, lack of necessary test conditions and test data, few specifications and varieties, and there is still a gap in the steel and specifications required for large molds and special molds. In terms of steel supply, Guangdong mechanical processing plant has not effectively solved the contradiction between the sporadic consumption of users and the supply and demand of mass production of steel mills. In addition, foreign mold steel has successively established sales outlets in China in recent years, but due to the influence of poor channels, weak technical service support, high price, foreign exchange settlement system and other factors, there is little promotion and application at present.
Although the auxiliary materials and special technologies for machining molds have been popularized and applied in recent years, mature production technologies have not been formed, and most of them are still in the experimental and exploratory stage, such as mold surface coating technology, mold surface heat treatment technology, mold guide pair lubrication technology, mold cavity sensing technology and lubrication technology, mold stress relief technology The anti fatigue and anti-corrosion technologies of molds have not yet fully formed productivity and are moving towards commercialization. Some key and important technologies also lack the protection of intellectual property rights.
The production of mold standard parts in China only formed small-scale production in the early 1980s. The degree of mold standardization and the use coverage of standard parts account for about 20%. Only about 30 varieties can be matched from the market, and are limited to small and medium-sized specifications. The supply of standard male and female dies and hot runner components has just begun. The production and supply channels of die bases and parts are not smooth, and the accuracy and quality are poor. The current situation of the industrial organization structure of die industry is that China's die industry is relatively backward, so it can not be called an independent industry so far. China's current mold production enterprises can be divided into four categories: professional mold factory, professional production for mold; The main task of the mold branch or workshop of the product factory is to supply the molds required by the product factory; The organization mode of the mold branch of the three foreign-funded enterprises is similar to that of the professional mold factory, mainly small and specialized; Township mold enterprises are similar to professional mold factories. Among them, the first type is the largest, and the mold output accounts for more than 70% of the total output. China's mold industry management system is decentralized. At present, there are 19 major industry departments manufacturing and using molds, and there is no unified management department. Relying solely on the overall planning of China mould industry association and focusing on tackling key problems, there are many difficulties in cross industry and cross department management.
Machining mould is suitable for small and medium-sized enterprises to organize production. When China's investment in technological transformation is inclined to large and medium-sized enterprises, the investment of small and medium-sized mould enterprises can not be guaranteed. Including the mold workshop and branch factory of the product factory, the investment can not be recovered soon after the technical transformation, and even they are heavily in debt, affecting the development.
Although most of the mould workshops and branches of Guangdong Machinery processing plants have strong technical force, good equipment conditions and high level of mould production, the utilization rate of equipment is low. China's mold price has been uncoordinated with its value for a long time, resulting in the phenomenon of "small self-economic benefits and large social benefits" in the mold industry“ Dry mold is not as good as dry mold standard parts, and dry standard parts are not as good as dry mold belt parts. Abnormal phenomena such as "dry belt production is not as good as processing products with molds" exist
