In 2003, China's automobile mold is mainly a small number of mold team for the industry's landmark enterprises, today's automobile mold enterprises have developed to dozens of, a number of rapid rise of private enterprises have a considerable scale. Both technically and in terms of production capacity, these enterprises have greatly exceeded the iconic enterprises of the year. As can be seen from the distribution of automobile stamping dies in the country, China's automobile dies have developed from the past to today's all over the country. In recent years, more than half of the molds and fixture equipment required by dozens of independent brands and joint venture brands listed in China are developed and manufactured by Chinese mold enterprises, and many car OEM manufacturers have handed over the most complex vehicle molds of Class B cars to Chinese mold enterprises for production. At present, there are more than 100 domestic automobile body mold manufacturing enterprises with a certain scale, of which 20 have an output value of more than 0.1 billion yuan. The number of large CNC machine tools is more than 800, which is close to or more than Germany, the United States and Japan.

Before 2003, domestic mold enterprises mainly produced truck and van molds, and car molds were at the level of producing structural molds. The production capacity of welding clamp enterprises is also limited to the production of internal parts of the welding fixture and component assembly fixture. At present, domestic mold enterprises gradually began to produce vehicle body-in-white mold, welding enterprises also have from the chassis assembly four door, side assembly to the body-in-white main welding line production capacity, and in the main technology has been close to the international advanced level.

The technical level of China's mold industry has also made considerable progress in recent years. Large, precision, complex, efficient and long-life mold on a new level. Large complex die to automobile cover mold as a representative, has been able to produce part of the new car cover mold, reflecting the high level of manufacturing technology of multi-position progressive die coverage. In terms of large plastic molds, it has been able to produce molds for automobile bumpers and integral dashboards. In terms of precision plastic molds, it has been able to produce multi-cavity small modulus gear molds and plastic molds. In terms of large-scale precision and complex die-casting molds, it has been able to produce die-casting molds for automobile rear axle gearboxes, radial tire active molds, etc., which have also reached a high level and can replace imported molds.

Many domestic enterprises have realized the three-dimensional solid processing of die casting foam model, and the main work of the model worker is to prepare the processing program in the computer room. This greatly improves the quality of the model, improves efficiency, and shortens the manufacturing cycle. In recent years, with the continuous introduction of advanced processing methods such as high-speed multi-function CNC machine tools and high-strength tools, rapid development has been achieved in the field of technical applications such as unmanned high-speed machining, mold surface fine machining, five-axis linkage machining, and computer virtual machining. Advanced technologies such as simulation and virtual reality have been applied in the early stage of mold clip development. The design of foreign stamping process spiral sand washing machine is a highly professional post with a clear division of labor. It needs team cooperation to complete this complex design process sand washing machine, which generally includes the design process of product pre-process analysis, process scheme prediction, model construction, process feasibility analysis, model repeated optimization and so on. Take the overall side of the car as an example, the ordinary side mold is generally 5 to 6 processes. A few years ago, Toyota of Japan changed the side wall from 5 processes to 4 processes, and increased its efforts in mold development and product development, achieving a big leap in the industry. The current research direction is to complete the stamping process of the whole side wall through three processes, which not only needs to improve the stamping process, but also needs the collaborative research and development of synchronous engineering. When designing the product of the whole side wall of the car, the feasibility of the stamping process should be fully considered.

Japan's Toyota, Germany's Volkswagen and other international leading automobile manufacturers have specialized stamping, welding, assembly, coating process personnel. These technicians work with the body designers of the R & D center to analyze the manufacturability of the product. From the body design to the tooling manufacturing follow the principle of unity, the degree of integration is very high, very conducive to the body quality, cost, cycle of the overall control. Although China's mold and welding clamp industry has made great progress, there are still some problems. Most of them are fighting on their own. It is difficult to communicate between mold manufacturers and welding clip manufacturers. Many problems are stranded in the production preparation stage of automobile manufacturers, which seriously restricts the product quality and output cycle of white body. In addition, due to the limitation of mold material and mold special structure, there is still a certain gap between the stamping process level of domestic automobile body mold and foreign industry. This is mainly manifested in the experience and experience of process designers. The types of models contacted by domestic process designers are too different from those of foreign process designers, which leads to some constraints on process design ideas.

Some advanced enterprises in the world have a high level of welding and assembly development capabilities, and have formed a cooperative network with a few enterprises with advanced vehicle welding and assembly process platforms as the core and many small and medium-sized welding and assembly enterprises with a high degree of specialization. Foreign countries such as Japan's Toyota, Germany's Volkswagen, France's Peugeot, the United States General Motors and other major automobile companies have applied three-dimensional digital process planning and simulation software for nearly a decade of history. Domestic welding line process planning for large production, high degree of automation of the lack of unified digital information management tools, has not yet formed this type of highly automated welding line planning capacity. Due to the rapid development of the industry, the technology and management of China's mold industry has also entered the fast lane, and has the ability to challenge the mold manufacturing industry in developed countries. The era of China's mold industry entering the international market on a large scale has arrived.

With the development of product segmentation and specialization in my country's mold industry, automobile molds are still the most widely driven and the industry is developing rapidly. Each car change requires thousands of molds, worth hundreds of millions of yuan. The main engine factory and closely matched mold companies have formed a strategic alliance of cooperative development, research, process debugging, and mass production. Automobile mold equipment is an important part of automobile equipment. In recent years, the automobile industry has accelerated the speed of change and the demand for market diversification has grown at an alarming rate, and the potential market for automobile molds is huge. First of all, automobile enterprises are assembly enterprises. In fact, the real technology is more in the hands of parts enterprises. The mass production of products of parts enterprises is realized by mold forming. In terms of automobile transmission system, steering system, body parts and engine products, we still rely on imports of high-end parts. Mold equipment is an important part of automobile equipment. Each new model of automobile needs thousands of molds, worth hundreds of millions of yuan. However, the manufacturing capacity of large precision molds in China is insufficient. For example, the full set of body dies for mid-range Passat exceeds 0.25 billion yuan, and the large plastic dies are about 35 million -40 million. The mid-range car cover dies and the full set of die and dashboard bumper plastic dies for cars below Class C in our country have been well produced, but at present, almost all the cover dies for high-end cars in our country are imported products.
