It is reported that the domestic gear mold industry is a mixed blessing. The joy is that the domestic gear mold production has a certain foundation, and the rapid development trend of plastic gear will also bring greater market space for gear mold. The worry is that compared with the advanced production level of foreign gear mold, there is still a certain gap in the level of domestic production of gear mold, and under the great development of gear industry, especially plastic gear industry, China’s response to market changes is not sharp enough, and supporting research is a little difficult with the market demand.
The plastic gear has the advantages of low transmission noise, vibration absorption, self lubrication and high production efficiency of mold processing. In recent years, the application of plastic gear in gear industry will be more and more, becoming a worldwide trend.
But at present, the middle and low-grade gear mould can be produced in China, and the high-grade gear mould mostly depends on import. There are not many factories specialized in making gear mould in China, most of which are made by gear factories themselves. In the application range of gear mould, the demand of plastic gear mould is large and the market potential is huge.
Related experts in the industry put forward three strategies for future development: accelerating the adjustment of industrial structure; in the future development, the gear mold industry should pay more attention to the strategic adjustment of its product structure first, so that the high-end mold with complex structure and high precision can get a faster development. At the same time, the mold industry should also closely follow the market demand to develop. Without the demand of products and the renewal of products, there will be no technological progress in the mold industry, and there will be no scale and grade of mold products. The level of mold technology, to a large extent, determines the quality of products, benefits and the ability to develop new products.
Second, speed up the implementation of industrial standards; at present, there is neither national standards nor ready-made industrial standards for the processing of gear mold, especially in the plastic gear mold. Technical standard is a kind of open standard, but it is very difficult to make product standard. We should consider many aspects such as experiment standard, precision standard and test device standard of gear mould.
Third, strengthen the cooperation density between industries; the development of modern industry is a collaborative relationship, which is equally important for the gear mold industry. This kind of cooperation is the direct cooperation of industry research. For example, several universities are engaged in the research of gear mold, the integration research and cooperation of gear industry and research institutions of some universities, and the integration research and cooperation of process equipment and plastic internal deformation law.
At the same time, in terms of the whole industry, the voice of gear mould is very small, and it is in a spontaneous state, and the establishment of relevant professional associations is to change this situation. This is to focus on discussing and solving the problems existing in the production of small module gear, so as to promote the development of domestic precision gear mold industry.
With the rapid development of gear industry, especially plastic gear industry, the domestic response to market changes is not sharp enough, supporting research is difficult to keep up with the market demand, and the domestic precision gear mold still needs to keep pace with the development level of the world gear mold.
