Analysis of China's automotive mold development

Automotive mold technology integrates many disciplines such as machinery, electronics, chemistry, optics, materials, computers, precision inspection, and information networks. It is a comprehensive high-disciplinary system project. The mold is the basic process equipment of the automobile industry. More than 90% of parts and components in automobile production rely on mold forming. At present, China is basically self-sufficient in molds such as trucks, light vehicles, and mini-vans, and can produce some car cover molds. However, most of the molds for cars still need to be imported, mainly body part cover molds and interior part molds. The annual import amount is more than 100 million US dollars.

The automotive mold industry is a high-input, high-risk industry. If companies do not consider their own actual ability and experience, they blindly seek to become bigger and better. The result is counterproductive and worthless. Automobile mold enterprises must take their own actual comprehensive ability, do what they can and be reasonably positioned. To abide by the principle of gradual and orderly progress, do a good job first, and then be quick. Especially for vehicle molds, companies have to go through the practice of multiple projects, and with years of experience and technical support, they can gradually take over.

The three-dimensional design of the mold is an important part of the digital mold technology and is the basis for the integration of mold design, manufacture, and inspection. Some practices taken abroad in the three-dimensional design of molds are worth learning from. Toyota, U.S. General Motors and other companies have achieved three-dimensional design of molds and achieved good results. In addition to facilitating the realization of integrated manufacturing, the three-dimensional design of the mold has another advantage that it is convenient for interference checking and can perform motion interference analysis, solving a problem in two-dimensional design.

The rapid development of the two industries is being promoted by the level of the mold industry, represented by automotive molds and IT molds, in which the current development of mobile phone molds is particularly popular. In the past, only some foreign mobile phone brands such as NOKIA and MOTOLOLA were able to complete parts. Now China's mold factories can do it and can be completed in a short time. This has also prompted the sudden emergence of Chinese mobile phones and cottage machines. The automotive industry is also obvious to all. As the global auto market shrinks, the Chinese auto industry continues to sing all the way. The auto production of domestic brands is constantly improving, and China's manufacturing industry is making continuous progress toward China. This is closely related to the fact that Chinese manufacturing companies pay attention to mold technology and continue to develop independent mold production. Take BYD as an example. BYD has invested a lot of financial and material resources to cultivate its own mold factory, and its technological level ranks first in the country.

The automotive mold market is very large, accounting for about half of the entire mold market in industrialized countries. The basic idea of ​​the automotive mold industry and technology development: To highlight the development as the theme, market-oriented, reform and technological innovation as the driving force, and structural adjustment as the main line, under the guidance of the national industrial policy, vigorously promote the optimization of the industrial organization structure And upgrade the industrial structure, accelerate the development of key products that are urgently needed in the market, and cultivate a batch of mold enterprises that have strong international competitiveness.
