China's auto panel mold industry development speed

The rapid development of the automotive industry has directly driven the rapid development of automotive panel molds. Following the "blowout" development in 2002 and 2003, China's auto industry still achieved a 14.1% increase in output in 2004, a rapid increase in sales growth of 15.5%, and the total automobile output has exceeded 5.07 million. In addition to the rapid development of output value, the development speed of automobile models has also been rapid in recent years. According to incomplete statistics, there is only one car, and currently there are more than 40 brands and more than 200 models. There are about 40 new cars listed in 2004. Whether it is production or models, it has already broken through the goals of the “10th Five-Year Plan” of the original automobile industry. Under such a new situation, there will be corresponding rapid development in the automotive panel mold market, which far exceeds the tenth five-year plan. In 2004, the output value of molds reached more than 53 billion yuan, which is more than 4 billion yuan more than the target of 49 billion yuan in 2005 that was originally planned for the 10th Five-Year Plan. The average annual growth rate of auto cover molds is even higher than the industry average, and the average annual growth rate is estimated to be close to 20%.

The rapid increase in production capacity As the demand for auto parts mold market is very strong, many companies have stepped up their technological transformation efforts, and some newly-built companies have also developed rapidly, which has greatly improved the production capacity of automotive panel parts. After technological transformation, the four major mold factories recognized in the industry (FAW Mold, Vehicle Auto Mold, Tianjin Automobile Mold, Sichuan Chengfei) have the ability to produce about 2 million working hours for large and medium-sized automotive panel molds. The output value exceeds 100 million yuan. Compared with 2000, capacity has more than doubled. In addition to these four homes, in recent years, there have emerged a group of nearly 10 companies that have an annual output of molds that can exceed or close to 100 million yuan. In addition, there are about 10 companies with an annual output value of 50 million yuan. These more than 20 automotive panel mold manufacturers are currently the main force, with a total capacity of 2 billion yuan. Coupled with other small businesses, it is estimated that the country currently has about 3 billion yuan in car cover mold production capacity.

From the perspective of recent developments, private enterprises have developed rapidly, and foreign-funded enterprises have also begun to enter China, of which Japanese-funded enterprises are the most active. Nowadays, more and more companies are producing car cover molds. It is estimated that there are more than 100 in the country. A large number of private auto mold manufacturing enterprises have become a fresh force that has emerged as a result of their large investment, high starting point, and clear service targets.

In addition to individual companies developing their own production capabilities, the ability to unite, coordinate, and collaborate among enterprises has also been greatly improved in recent years. Some regions have formed prototypes of automobile cover mold assembly production bases. These agglomeration production bases have formed automobiles. Mold enterprise groups and professional close supply chain. All these are very helpful to the development of our capabilities. In addition to Shanghai and Botou City, Hebei Province, where a large number of automobile-covered mold manufacturing companies are concentrated, Shiyan City, Tianjin City and surrounding areas, Harbin, Chengdu and other places have relatively concentrated on a number of automotive panel mold production. The company has formed a number of collaborative relationships to improve overall capabilities.

With the expansion of the size of some mold “leading” companies and the increase in organization, coordination capacity and technical strength, the ability of individual mold companies to undertake vehicle molds has been formed, and even a whole vehicle mold of multiple models can be accepted within one year. At the same time, the industry has initially formed a specialized division of labor and group management, which has enhanced the overall strength of the mold enterprises.

Significant progress has been made in technological advances. With the rapid development of vehicle production and models in recent years, the price of automobiles has decreased year by year. The result of price cuts on cars has forced automakers to reduce costs, which in turn has imposed price cuts on mold companies. For this, many mold factories think that this is unfavorable to the mold factory, but some mold factories think this is good news. Because automakers want to reduce their mold prices, of course all molds, including imported and domestic ones, are now much lower in price than foreign ones. Therefore, automakers will take part in reducing mold purchase costs. The molds are transferred from foreign purchases to domestic purchases. In this way, not only mold factory orders will increase, but also this part of the mold price will be optimistic.

This is a good reason. Whether it is accepting the molds that were originally imported and turned into domestic purchases, or accepting orders that were originally made domestically and now require price reductions, mold manufacturing companies are required to make progress in management and technology to become competent. This forced mold companies to actively adopt new technologies, strive to improve business management, improve their overall quality and core competitiveness. To be efficient in technology, to be effective in management, has become the consensus of many mold factories.

At present, the gap between China's auto mold enterprises and the international level in major hardware is rapidly shrinking. Even a number of companies have reached the advanced level in the world, and technological progress is evident.

Regarding the level of equipment, no matter whether it is a newly-built enterprise or an old enterprise that has undergone technological transformation in recent years, it has purchased a large number of advanced CNC equipment without exception. These devices include three-axis to five-axis high-speed machining tools and large gantry doors. Machining centers and CNC milling machines, advanced large-scale measuring and debugging equipment, and multi-axis CNC laser cutting machines. As a result, the level and ability to produce automotive panel molds have greatly improved. In the past, it was difficult for a company to complete the molds of the entire vehicle within one year. Now, some key enterprises have fully had this ability. Individual companies also have the ability to simultaneously complete 4 to 5 models of complete molds within one year through industry collaboration. Most companies are also equipped with many advanced software. Judging from the current level of equipment, the country already has the ability to complete more than 20 vehicle models in one year.

Secondly, in terms of design and processing technology, companies have increasingly used three-dimensional cads. At the same time, cae technology has also been widely used. As the core technology of automotive large-scale cover mold development - cae technology, the current cae software has been upgraded in the traditional only for forming analysis, can participate in the whole process of stamping process, in analyzing the breadth and practicality of the content There have been significant improvements in accuracy and accuracy. This has a significant role in product design and process analysis, improving the success rate of molds, especially drawing dies, shortening the mold manufacturing cycle, and improving mold quality. Advanced technologies such as digital manufacturing, reverse engineering, concurrent engineering, agile manufacturing, and lean manufacturing have also been applied in the production of automotive panel molds and have produced good results.

Although it is very difficult to use cappatch in mold factories, there are many successful examples. The high-speed machining technology that was rarely used before is now being used more and more, and it can be said that it has reached the stage of extensive application. Others such as measurement technology, surface coating technology, integrated inspection tooling, standardized application, and the successful combination of rapid prototyping technology and rapid economical Die Casting have made many advances in recent years.

Due to the improvement of equipment level and design and processing technology, as well as the improvement of personnel quality and the application of some new technologies, the level of domestic automobile panel molds has also been greatly improved in recent years.

The improvement of mold level is various and reflected in the whole process of mold production.

Now, the mid-range sedan, including the tough overall side panels and fenders, has been able to produce all the cover molds domestically. The molds and some export molds for foreign vehicles of joint ventures can also be accepted by foreign companies (such as Japan and Germany). Some domestic backbone enterprises have realized their ability to transition from local parts and components, mid-to-low-end sedan molds, to vehicle parts and middle-to-high-end sedan molds. Large-scale continuous-mode and multi-position progressive dies that are matched with automatic presses now have a higher level of products in China. The gap between the domestic high-end mold level and foreign countries is narrowing. The phenomenon that all mid-to-high-end car molds are dependent on imports is gradually changing. In recent years, the emergence of cover molds for the production of automated production lines and the emergence of large-scale multi-station automation molds have also demonstrated the progress in the overall level and strength of mold technology quality.

Due to the popularization and application of cad/cae technology, some domestic enterprises have approached foreign standards in the analysis of stamping process design in dl diagram. The use of standardized structures, standard parts, and typical structures and their flexible handling on these foundations have resulted in a high degree of composite structure, reasonable structural layout, and reliable use.

With the use of high-performance processing equipment and the maturity of cam technology, some organizations have also established corresponding knowledge bases, tool libraries, spindle head libraries, etc. Virtual machining can be implemented to check interference. Some companies have also independently developed software that can avoid over-cutting. After the application, they can completely prevent over-cutting of CNC machine tools. The application of precision machining, multi-axis linkage processing, and inclination processing methods has improved the quality of mold manufacturing. The progress of solid casting technology provides a better casting blank for the die. Many varieties and high-quality standard parts provide the conditions for mold standardization, which greatly shortens the production cycle of the mold and also reduces the cost.
