Current status and development prospects of automotive stamping die industry
Moulds are processing tools that process raw materials and give them complete configurations and precise dimensions. They are mainly used for high-efficiency and mass production of related parts and components in industrial products. With the development of modern industry, the application of molds has become more and more extensive. In products such as automobiles, electronics, instrumentation, home appliances, aerospace, building materials, motors and communication equipment, about 60%-80% of the parts are dependent on Mold processing and forming, so it is called the “mother of industry”.
Mold is an important part of the equipment manufacturing industry, and its high degree of industrial relevance is one of the important guarantees for industrial upgrading and technological progress. It is estimated that the proportion of molds that can drive related industries is about 1:100, that is, the development of molds is 100 million yuan, which can drive related industries to 10 billion yuan.
There are a wide range of mold applications, many types, and many classification methods. According to the nature of mold forming process, molds can be classified into stamping molds, plastic molds, casting molds, and forging molds.
Overview of the automotive Stamping Die industry
In the downstream mold industry, the automobile manufacturing industry uses a large amount of molds. In developed countries such as the United States, Germany, and Japan, the output value of the automobile mold industry accounts for more than 40% of the total output value of the mold industry. In my country, there are about 1/3 Mould products serve the automobile manufacturing industry. Generally, the production of an ordinary car requires more than 1,000 to 1,500 sets of stamping dies, which accounts for about 40% of the output value of all the molds required for the production of the entire vehicle.
Automobile stamping die is an important process equipment for automobile production, and its design and manufacturing time accounts for about 2/3 of the automobile development cycle, which is one of the main restrictive factors for automobile remodeling. Automobile stamping dies have the characteristics of large size, complex working surface, and high technical standards, which are technology-intensive products. In the past, automotive stamping dies generally used the structural design of single-process molds and composite molds. With the advancement of technology and the improvement of equipment levels, multi-station molds and progressive dies that can reduce costs and improve production efficiency are gradually being used in automotive stamping dies. In design and manufacturing, it has become the development direction of automobile stamping die manufacturing technology.
The global automotive stamping die market capacity
Beginning in 2001, the global mold industry has been on a steady upward trend, with an average growth rate of more than 5%. By 2012, the global mold industry market has reached 94.5 billion U.S. dollars. In developed countries such as the United States, Germany, and Japan, the demand for automotive-related molds accounts for more than 40% of the total demand for molds. Based on this estimate, the global automotive mold market has reached 37 billion U.S. dollars. According to the calculation of the output value of auto stamping dies accounting for 40% of the output value of auto dies, the global auto stamping die market is about 15 billion US dollars. At present, North America, Europe, and Japan, as the traditional demand markets for automotive stamping dies, still occupy an important position in global demand, and their market demand growth rate will remain at a relatively stable level in the next few years. Compared with developed countries such as the United States, Germany, and Japan, the automotive industry in emerging economies such as China, India, Brazil and Russia has developed rapidly. The related demand has expanded the demand for the global automotive stamping die market, and will gradually become the global automotive stamping The new engine of mold demand growth.
Analysis of global automotive stamping die market prospects and demands
The development of the automotive stamping die industry is closely related to the development of the downstream automotive industry. The steady and rapid development of the downstream automotive industry will greatly promote the development of the automotive stamping die industry.
The steady and rapid development of the automobile industry has created a good environment for the development of the automobile stamping die industry. In the production process of automobiles, more than 90% of the parts and components need to be formed by molds, and about 1,000 to 1,500 stamping dies are required to manufacture an ordinary car. The automobile production of a country reflects to a certain extent the overall situation of the automobile molds that the country needs. After the 2008 financial crisis, traditional automobile production powerhouses such as the United States, Germany, and Japan recovered moderately, while demand for automobiles in emerging market countries such as China, India, and Brazil grew rapidly. According to the forecast of the automotive research institute IHS, the global light vehicle production growth rate will reach 3.6% from 2013 to 2020, of which the growth rate of developing countries will reach 5.7%, and the growth rate of developed countries will remain at about 1.2%. The steady and rapid development has created a good environment for the development of the automotive stamping die industry.
Industry development trends
1. The domestic medium and low-end automotive stamping die market is relatively saturated, and the pace of localization in the high-end market is accelerating
In recent years, the number of automobile stamping die manufacturing enterprises in my country has been increasing, and the production capacity has also increased. However, the industry is mostly small and medium-sized enterprises with limited equipment and R&D investment. The main production of low-end stamping die products with lower technical requirements has caused the The low-end automotive stamping die market is relatively saturated and the competition is fierce, while the domestic self-sufficiency rate in the high-end market is relatively low, only about 60%.
Some leading domestic automobile stamping die manufacturers have introduced advanced foreign production equipment and technologies, strengthened technological research and development and production process innovation to raise mold products to a new level, and realized the design and manufacture of C-level automotive stamping dies, and large-scale progress Substantial breakthroughs have been made in molds, and large-scale progressive molds with a length of 6m have been successfully developed. In the segment of high-end automotive stamping mold products, it competes with international manufacturers in all aspects, which promotes the rapid development of the import substitution market and further accelerates the pace of mold localization. . Self-owned brand auto companies such as Chery, Great Wall, and Brilliance have successively shifted from imports to domestic procurement of vehicle molds required for vehicle development, while joint venture auto companies such as Volkswagen and General Motors have also begun to shift high-end automotive stamping dies to domestic procurement. The localization of high-end automotive stamping dies has further expanded the domestic market demand for automotive stamping dies.
2. The degree of specialization and commercialization of domestic automobile stamping die production has further improved
Due to the historical reasons of the development of my country’s automobile industry, most domestic automobile stamping die companies have developed dependent on automobile manufacturers, and they regard the provision of mold matching for automobile OEMs as the first priority. This has led to the general lack of specialization of automotive stamping die companies, marketization and socialization. The degree of chemical procurement is low. During the “Eleventh Five-Year Plan” period, my country has policies to encourage the development of the automotive stamping die industry towards specialization and commercialization, encourages the separation of main and subsidiary, and makes mold production from subsidiary to independent, and more and more subsidiary mold companies increase their proportion of accepting external orders. Or reorganized into an independent mold enterprise. At present, the social procurement of molds only accounts for about 45% of the molds produced in China each year. In the future, it will further increase and approach the level of social procurement of more than 70% of foreign molds.
3. Automobile stamping die manufacturers extend to the downstream industry chain
With the rapid development of the automotive stamping die industry, the technical level of the industry has improved rapidly, and the competition has intensified. The simple design and manufacturing mode can no longer meet the needs of market competition. Some major enterprises in the industry have begun to move downstream with molds as the core. The industrial chain is extended, the stamping production line is established, and the molds produced are used to directly produce automotive stamping parts for customers. The advantage of this shift to the downstream industry chain with molds as the core lies in the following: Manufacturers have established a long-term and stable cooperative relationship. Direct supply of stamping products can better serve automobile manufacturers; the second is to use molds produced for customers to directly produce auto parts, which can effectively reduce production costs and improve production efficiency; third, scale The advantages are obvious. Automotive stamping dies are customized products, and automotive stamping parts can be mass-produced continuously, which increases the scale of enterprise production. In view of the above considerations, the business scope of major manufacturers in the automotive stamping die industry tends to extend to the downstream industry chain, and actively cooperate with automotive vehicle manufacturers to provide “integrated” molds and product services.
4. Wide application of progressive die
Stamping parts with complex shapes, especially small and medium-sized complex stamping parts that require multiple stamping dies to be punched sequentially according to traditional processes, are increasingly formed by progressive dies. About 30%-40% of automotive stamping parts in developed countries have been produced using progressive dies, while the proportion of progressive dies in my country’s auto parts stamping dies is only about 10%. Progressive dies will be one of the most important mold products in my country. one.
Progressive die is a safe, high-precision, high-efficiency, and long-life die. It is one of the development directions of stamping dies, which can significantly reduce the production cost of small and medium-sized stamping parts. Progressive dies can continuously complete blanking, bending, stretching, forming and other processes by controlling the feeding distance and the punching of each station to realize automation and mass punching. With the development of high efficiency and automation of automobile stamping production, the application of progressive dies in the production of automobile stamping parts will be more extensive.
