The automotive mold industry has developed rapidly and has made great progress. However, compared with the advanced level in foreign countries, there is still a clear gap. Mainly in the following points: First, poor manufacturing accuracy. Taking seals as an example, many people have reported that the sealing performance of China's domestic cars is not good. In fact, this is not only related to the level of manufacturing of sealing materials and seals, but also directly related to the level of related molds. According to Luo Baihui, Secretary-General of the International Modeling Association, currently foreign auto companies are implementing the "2 mm" project, but in China, a single part can still be achieved. There are no guarantees for assembling hundreds of parts together. The key lies in the mold. The second is short die life. Taking aluminum die casting as an example, the advanced level in foreign countries has reached more than one million times, while China has only 200,000 times, only one-fifth of the foreign level. The third is the long development cycle of the mold. In the past, China's automobile models have remained unchanged for decades and the development of automotive molds has been slow. With the fierce competition, the speed of replacement of automotive products has accelerated, and the mold industry has been required to shorten the cycle of mold development.

The automobile industry is one of the major user industries of the current mold. According to the development planning requirements of the automobile industry, it is necessary to support the establishment of a specialized mold design and manufacturing center, and it is extremely urgent to improve the design and manufacturing capabilities of automotive molds.

1. In recent years, the rapid development of China's auto industry, the rapid increase in the demand for molds, the rapid increase in the number of mold companies for automotive mold service. The automobile mold industry of the automotive industry, technical force, equipment preparation and production capacity are mainly based on large-scale molds for automotive body parts, and use their own strengths and capabilities to concentrate on solving molds such as body parts and other large-scale cover molds. For some small and medium-sized parts of the mold has no more investment capacity, can only turn to the community, so that many mold companies supporting the production of small and medium-sized automotive molds.

2. The production process of the automobile has been greatly developed. The stamping process has passed modeling, cae finite element analysis, and die stamping process, which shortens the manufacturing and trial cycle of the mold and reduces the cost. In the manufacturing process, most of the key equipments such as large-scale machining centers are used, basically in line with foreign advanced processing technologies. Several large automobile mold enterprises can, in principle, make complete sets of tooling for automobile molds, such as the recent introduction of technology by FAW Mold. After the change, the processing center has reached 36 sets, and Beijing BYD Mould Company has more than 25 sets. Dongfeng Auto Mould, Tian Steam Mould and Cheng Fei Mould all have certain processing strength.

3. The manufacturing cycle of automotive molds is shortened. The technical transformation and the improvement of the technical level have shortened the cycle of automobile modification. From the original one-and-a-half years to one year and then to eight months, it can complete the complete set of molds for the vehicle models, and accelerate the new car. The models are available on the market.

4. The investment in technical reforms has increased and the income recovery has been difficult. The mold enterprises in the automotive industry have large capital investment in technological transformation. Generally, they need more than RMB 1-3 billion in order to expand the production scale; the mold output also increases from the original RMB 150 million to the output of RMB 3-4 billion. It takes about 10 years for a 10% return to be obtained, and it is only under the big tree of the automobile group that it can be transformed into a larger technological equipment. SMEs are also affected by difficulties in financing the technical reform funds in the process of manufacturing automotive molds. Due to the large space for the development of automotive molds, the large demand, and the short time and concentration requirements, there is no corresponding key equipment processing can not be completed, must be appropriate investment, coupled with the company through restructuring, so funds, loans There are certain difficulties.

5. The export volume of auto parts increased. Overseas auto manufacturing companies have entered China to purchase global auto parts and parts, which have increased the export volume of parts and components. However, in order to meet the international market prices, the original production technology cannot be adapted and the processing cost is large. In order to meet the needs of the international market, it must be Compression costs and other costs. Therefore, from the application of the mold structure, it is necessary to replace the traditional single-process mold with multi-position progressive molds and transfer molds, so that the manufacturing precision and technical level of the molds must be upgraded to a higher level, and technical reforms need to be intensified. The intensity of the investment, including the key processing equipment for mold processing and large-tonnage stamping equipment, is suitable for multi-position transfer and progressive die stamping.

6. Further improvement of technology and application and development of cad/cae/cam.

Technological progress is the basis for the development of the mold industry. For cad/cam, it must have strong development capabilities and applications. Advanced design techniques and manufacturing techniques must be used. Currently, key equipments use advanced cnc control systems, and how to use them Development is the key to shorten the cycle of manufacturing trials, and the application of CAE finite element analysis is currently the weakest link.

In general, China's mold with low technological content has been oversupply, and there is a narrow market for profit; while middle and high-grade molds with high technological content are far from adapting to the needs of economic development, sophisticated and complex stamping dies, sedan covers, and other high-end models. The mold still has a lot of room for development. The future development direction of China's auto mold industry should focus on product structure adjustment and positioning. To further enhance the manufacturing technology of the mold, occupy the high-end mold market with complex structure, high precision, and high technical content.

At present, the annual production capacity of the domestic automotive stamping industry is only 8 to 9 billion yuan, while the demand for molds in the Chinese auto market has reached more than 20 billion yuan. Under the current situation, the rapid development of China's automobile industry puts forward higher and higher requirements for the mold industry, and it also provides a huge impetus for its development.
