Pay attention to the breakthrough of domestic injection molding machine

The extensive application of plastic products has provided an inexhaustible motive force for the development of the plastics machine industry. The tremendous potential for development of the plastics industry in China has opened up a vast space for the rapid growth of the Chinese plastics machinery industry. However, it is worth noting that the total sales volume of China's annual production of presses is less than the total amount of imported presses, especially in the information industry and other high-tech products. The differences in the benefits caused by technical differences between domestic presses and imported presses are enormous.
At present, the injection molding machines are divided into four types: elbow type (mechanical type), full hydraulic type, all-electric type, and electric/hydraulic type. These four types each have their own advantages and disadvantages, and each has its own market. In our country, the product structure is not very reasonable, and the elbow type is dominant in the market, and all-electric injection molding machines are still “legs” in the country. At present, no one company has mass production, and only sample machines are used for promotion. The key to this problem is that the core technology is in the hands of foreign manufacturers. The main components such as servo motors and ball screws are all dependent on imports. The largest part of the added value is taken away by foreign manufacturers, and it also brings after-sales service problems. In addition, the electric/hydraulic hybrid is still a blank in China. In the future, with the expansion of the application range of high-precision plastic parts and the reduction of the manufacturing cost of injection molding machines, all-electric injection molding machines have a lot of room for development. The electric/hydraulic injection molding machine is a new type integrating hydraulic and electric drive. Injection molding machine, which combines the advantages of full hydraulic high performance and all-electric energy-saving advantages, has become the direction of the development of today's precision injection molding machine. China is the world's largest information industry market. More than 90% of the plastic parts of the mobile phone body are produced by foreign presses. The digital industry, which uses plastic as the main raw material, is also out of the question.
From the development point of view, China's injection molding machines started relatively late. If they rely solely on the introduction, it is difficult to achieve transformation beyond them. It is difficult to find a position in the international competition. For this reason, people in the industry have put forward a brand-new point of view. The introduction is not necessarily the most advanced. If the imported technology is at least 10 years apart from the rest of the world and it needs to catch up, it must start with the invention. No matter whether it is a fully hydraulic type, all-electric type, electric/hydraulic hybrid type, or a toggle type with the largest amount of domestic use, it cannot give up the invention because it has the largest market and application scale, and it still has to focus on improving stability and improving efficiency. Reducing energy consumption for retrofitting and upgrading. Full hydraulic pressure is gradually improved from the traditional single-cylinder flooding to the current two-plate direct pressure type.
At present, the way to optimize the structure of injection molding machines in China is to increase the input and development of high-precision, high-tech injection molding machines. Injection molding machine research and development is characterized by a long development cycle, large investment, under normal circumstances, from the invention to the product about 5 to 10 years, but it is understood that Guangdong Kenli Machinery Co., Ltd. developed a four-cylinder hydraulic injection molding machine, It took 14 years from R&D to mass production.
This is due to the technical difficulty and the lack of funds and talent. In addition, at present, the country's policy of introducing tariffs and value-added tax on the introduction of advanced equipment is a heavy blow to enterprises that emphasize scientific research and development.
To this end, we must optimize the structure of our injection molding machines and develop high-precision, high-tech injection molding machines. The state must provide necessary support. In addition to setting up special technical funds, preferential policies should be given on taxes and loans, injection molding machine manufacturers should focus on In the regions, the government will also introduce supporting preferential policies for the introduction of talents, increase the enthusiasm for enterprise development, and lay a foundation for turning China into a strong machine-building country.
