The development of small and medium-sized mold enterprises: Accelerating the development of high-grade molds

Recently, the Chinese mold market is in a period of rapid growth, especially in plastics and rubber molds, and it has made great progress. From the import and export data of China's molds in recent years, it can be seen that the amount of imported plastic molds is much higher than the export amount. The proportion of import and export of plastic mold products to improve the import and export status of plastic molds in China must accelerate the development of domestic plastic molds. To this end, it is necessary to break through the two bottlenecks that restrict the development of the mold industry as soon as possible. One is that the standardization rate of molds is insufficient, which inevitably leads to longer delivery times and at the same time makes it difficult for users to replace parts. The low degree of standardization of molds directly restricts the specialized division of labor and collaboration of molds and commercial circulation, and also limits the export of molds. In 2011, the degree of standardization and commercialization of molds in China was around 55%, and the degree of commercialization in developed countries was 70%. Compared with 80%, there is a big gap.

Relevant experts believe that another major reason for restricting the development of molds is the low capacity of domestic production of high-precision molds. With the continuous development of the plastics industry, the development of precision, large-scale, complex, long-life plastic molds will exceed the total development speed. At the same time, due to imports of molds in recent years, precision, large-scale, complex, long-life molds account for the majority, so from the perspective of reducing imports and increasing localization rates, the market share of such high-end molds will also gradually increase.

With the outward transfer of mold industry and technology in developed countries and the adjustment of China's industrial structure, the demand for precision molds related to cars, home appliances and electronics has been increasing. The speed, quality, cost, and services have accelerated the pace of the mold industry. The pace of competition will continue to improve the technical standards in domestic mold standardization and precision. After years of efforts, plastic mold standard mold bases, standard push rods and springs have been more and more widely used in China, and some domestically produced hot runner system components have emerged; targeting market-critical parts, micro-holes, and fines The processing requirements of structural components, the pursuit of precision mold development to increase the added value of products, has become the development of SMEs.

In the future, molds will be developed toward large-scale, high-precision, multi-functional composites, etc. The proportion of hot runner molds in plastic molds will gradually increase, and with the continuous improvement and development of plastic molding processes, gas-assisted molds and high pressure Injection molding and other processes will also follow the mold. At the same time, due to the fact that in recent years, China has used about 2 billion US dollars per year to import molds, among which precision, large-scale, complex, and long-life molds account for the majority. From the perspective of reducing imports, China should also accelerate the development of high-grade plastic molds.
