The mold is the basic process equipment for industrial production, and the mold industry is an integral part of the high-tech industry. In the design and manufacture of integrated circuits that belong to the high-tech field, precision lead-in dies for lead frames and precision integrated-circuit lamination dies cannot be omitted; the manufacture of computer casings, connectors, and many components must also include precision plastic dies. And precision stamping dies; the development of digital electronic products (including communications products), no precision molds do not work. It is widely used in the manufacture of electronics, automobiles, motors, appliances, instrumentation, home appliances, and communications.
Not only electronic products, but also in the field of aerospace can not be separated from precision molds. For example, aspherical reflectors for airborne infrared receivers with a shape error of less than 0.1 to 0.3μm must be formed with a high-precision plastic mold. Therefore, it can be said that many high-precision molds are part of the high-tech industry. Some companies that produce high-precision molds have been named "high-tech enterprises."
Prior to the 20th century workshop, the mold development in China was not satisfactory, but since 1989, the State Council promulgated the "Decision on the Main Points of the Current Industrial Policy," and listed the mold as the first in the technological industrial technological transformation sequence. Since 1997, the country has successively included molds and processing technologies and equipment in industries that are encouraged by the "national key" and have given strong support. After China joined wto, it was praised as a "magnetic industry" mold industry by developed countries such as Europe and America. Some countries have shifted their manufacturing industries to China, and the mold industry is facing unprecedented opportunities for development.
First, automotive molds: China's auto and motorcycle market competition has become fierce. The model cars that have remained unchanged for decades or decades will be eliminated. Consumers are pursuing better performance and better formulation of vehicles. The appearance will also have a higher desire. Cars and motorcycles can only adapt to buyers' appetites if they unveil new products and models without interruption. Each type of car requires thousands of molds and the price is 100 million yuan. Each type of motorcycle must have nearly 1,000 molds worth more than 10 million yuan. And each type of car will have 80% of the mold to be eliminated.
The second is the home appliance mould: Now the production of a refrigerator requires about 350 molds, with a value of 4 million yuan; the production of an automatic washing machine requires 200 molds with a value of 30 million yuan; there are 20 plastic molds for producing an air conditioner. Worth 1.5 million yuan.
The third is the electronic and telecommunications product mold: In this type of mold market, audio and video products account for the bulk of the output, especially color TV molds. The production of a computer requires more than 30 molds, and because of the rapid development of the communications industry, communication products have also been updated quickly, and the demand for molds is also great.
Fourth, in terms of construction and building materials, plastic doors and windows, plastic drainage pipes and decorative plastic products will have a big development in the next five years. By 2010, the penetration rate of plastic doors and windows and the penetration rate of plastic pipes will reach 30% to 50%, and the demand for molds will increase greatly. The mold enterprises that produce plastic pipe fittings, doors and windows have a good prospect of development and will not be affected after joining the WTO. Obviously, the mold industry has moved from relying on imported subsidiary industries to independent new industries. China has become a big country for mold production and consumption. The world mold production center is also shifting to China. However, at present, there are still many imperfections in the development of China's mold industry, and it needs to continue to improve. The specific performance is: the mold with low technological content has been oversupply, while the medium and high-grade molds with high technological content are far from the needs of the national economic development, such as precision and complex stamping molds and plastic molds, car cover molds, and electronic connections. High-end molds such as plug-ins and other electronic products are still heavily dependent on imports. In the past five years, China’s average annual imports of molds have reached approximately US$1.12 billion. In 2003, it imported nearly 1.37 billion US dollars worth of molds. This does not include molds that come with equipment and production lines as accessories.
Mold industry is an important area of ​​high-tech industrialization. In the new investment of mold enterprises, the input of processing equipment accounts for 80%. According to statistics, the country has about 4 billion yuan in the mold equipment market, but also every year at a rate of about 20% growth.
Therefore, the key to the development of the mold industry is to use information technology to drive and upgrade the manufacturing technology level of the mold industry. At present, the application of cad/cae/cam technology and rapid model manufacturing technology in the mold industry has led to a major change in the design and manufacturing technology of molds. In addition, the application of CNC precision and high-efficiency machining equipment in the development and manufacturing of molds, such as five-axis machining tools and high-speed milling, has greatly improved the level of development in the mold industry.
Not only electronic products, but also in the field of aerospace can not be separated from precision molds.
