1985~2015 was the 30 years of rapid progress in China's tire mold industry. In the past 30 years, China's tire mold industry has grown from small to large, with reasonable layout, steady development, rapid progress and going global, and achieved remarkable results. China's tire mold industry is not only the follower and witness of the brilliant achievements of China's rubber industry, but also the promoter and executor of the development of China's tire industry.
Enterprise scale from small to large
Over the past 30 years, China's tire industry has developed at a high speed, and the tire mold industry supporting it has also maintained a good momentum of development. At present, China has become a big tire mold manufacturing country, but before that, China's tire mold industry was very small, the technological level was very backward, the production capacity was very low, and the scale of enterprises producing tire mold was also very small.
In the 1960s, the tire mold was opened with a file, bench vise and chisel; In the 1970s, ordinary turning, milling, planing, grinding and other equipment were used to manufacture moulds; In the 1980s and 1990s, we introduced and digested the advanced manufacturing technology of radial tire flexible mold from abroad, began to purchase new special equipment for mold processing, invested a huge amount of research and development and technical transformation funds, and purchased foreign CNC machine tools, etc. with a large amount of money. The top-brand six-axis five-linkage machining center, which used 800000 euros, is no longer satisfied with the domestic low-end market, and has been engaged in international competition. Now, the tire mold has entered the fourth development milestone. "Innovation", "patents" and even "brands" are increasingly valued by industry entrepreneurs. The technological content of the mold is constantly improving, more and more high-tech products are available, and the mold processing equipment is becoming more and more professional.
Since the new century, the rapid development of China's tire industry has brought broad development space for domestic tire molds. In addition, due to cost and market factors, the focus of mold manufacturing in developed countries has gradually shifted to developing countries represented by China. Comprehensive factors at home and abroad promote the rapid development of the domestic tire mold industry, and many new tire mold enterprises have emerged. At present, the current situation of tire mold industry is as follows:
1、 There are many manufacturers.
At present, there are about 100 enterprises producing tire molds nationwide, about 30 enterprises above the designated size, and 2 listed companies. In recent years, private tire mold enterprises have developed rapidly. The overall production capacity of private enterprises has occupied an absolute advantage, and the technology and manufacturing equipment are leading. They are the main force to achieve a powerful tire mold country.
At present, China's local tire manufacturers almost all purchase molds in China, and rarely import them; Foreign tire manufacturers in China, except for a few molds with confidential patterns provided by self-built mold factories, most of the other tire molds are purchased from Chinese manufacturers. In addition, China's tire molds have been exported in large quantities in recent years, and the world's major tire giants are purchasing tire molds made in China in large quantities.
2、 It is the largest tire mold enterprise in the world.
Shandong Haomai Group Co., Ltd. is now the world's largest tire mold manufacturer. In 2013, the sales revenue of tire mold was 1 billion yuan, with an estimated increase of about 50% in 2014. Both Julun and Tianyang have ranked among the top in the world tire mold industry. The rapid development of China's tire mold enterprises, the scale of enterprises and the number of employees have surprised foreign counterparts.
The development of China's tire mold manufacturing industry is seriously unbalanced, the two levels of differentiation are serious, the enterprises differ greatly, and the industrial concentration is relatively high. A few large enterprises have strong technological innovation ability and advanced technological equipment, and have formed a strong competitiveness in the world, and have started to set up branches abroad. However, many small and medium-sized enterprises are seriously lack of competitiveness and development potential. Therefore, although a few enterprises have had some international influence, the entire industry has not yet formed a prominent competitive advantage in the world.
3、 It has advanced and large number of mold processing equipment.
Most of China's tire mold enterprises have been established and developed over the past 10 years. With the technological transformation of the old mold enterprises, almost all of them have introduced the world's advanced mold processing equipment, such as large high-precision CNC milling machines and five-axis processing equipment.
At present, the widely used special tire mold production equipment includes precision, high-speed, CNC lathe, CNC milling and other processing equipment, such as special electric spark molding machine for tire mold, special engraving machine, CNC cutting machine, etc. The application of NC machining technology has improved the development of traditional manufacturing industry as a whole, and its technical content is very high, involving many aspects, including the rapid and efficient NC machining programming, multi-axis linkage machining of spatial free-form surfaces, cutting of difficult-to-machine materials, the application of high-speed cutting, and the standardization and standardization of NC process programming. In the field of mould inspection equipment, CMM detector, digital image metallographic analyzer, hardness tester, surface roughness tester, laser interferometer, processing equipment, test and trial equipment, etc. are widely used.
The introduction, absorption and development of a series of high-tech special equipment not only solved the processing problems such as multi-curve and multi-curve connection of tire mold cavity, but also made China's tire mold production realize the development of mechanization, informatization and intelligence.
Rapid technological progress in the industry
The relatively large tire mold enterprises in foreign countries have a history of development in recent decades or hundreds of years. However, most of the development time of China's tire mold enterprises is basically in these ten years. Since the beginning of the 21st century, China's tire mold industry has entered a period of rapid development, and the technological level of products has been significantly improved. Now, processing a pair of tire mold can be completed in less than one month. Not only the production efficiency is greatly improved, but also the edges and corners of the pattern are clear, the pattern pattern pattern is clear, the depth and spacing of the pattern are equal, and the appearance of the product is very exquisite. Not only greatly improved the curing efficiency, but also the vulcanized tires are very beautiful. It can be said that the technological progress of tire mold has promoted the rapid development of the tire industry, and its relationship is mutually reinforcing.
At present, there are two major processing technologies of tire mold in China, namely conical and inclined plane, forming a situation where three major processing technologies of precision casting, electric spark and CNC engraving coexist. The design of tire mold, especially the radial tire mold with complex structure, has changed from the traditional manual experience design to the computer-aided design method. The digital mold technology such as CAD/CAE/CAM has been widely used in the design and manufacturing to digitize the mold design, analysis, processing, inspection, test and other work. In addition, the application of advanced manufacturing technologies such as computer simulation, concurrent engineering, artificial intelligence, rapid prototyping manufacturing, as well as standardized and specialized production in the molding process have greatly improved the processing efficiency and precision of tire molds.
Key enterprises plan global layout
In 2013, the sales volume of China's tire mold industry was 3.88 billion yuan, of which the export volume was 7.9 billion yuan, accounting for about 20% of the sales revenue of the entire industry. Haomai Group Co., Ltd., the leading enterprise in the industry, has become the largest exporter of Chinese mold enterprises, with the export value of 73 million US dollars in 2013.
China is not only a major manufacturer of tire molds, but also a major exporter of tire molds, which is also an important sign of the rapid progress of China's tire mold industry, and also shows that tire mold enterprises have the ability to meet the needs of the international market. In the next 5 to 10 years, the mold export situation is still good, and the structure of export mold will also change with the improvement of technology. More mold exports with high technology content and high added value will become the mainstream.
At the same time, China's tire mold manufacturing globalization has also taken a key step.
After the acquisition of GMS in the United States in 2013, Haomai Group Co., Ltd. has established service centers in the United States, Europe, South America, India, Southeast Asia and Japan. At the same time, there are branches in China, such as Kunshan Haomai, Guiyang Haomai, Liaoning Haomai and Tianjin Haomai. At present, the company has shifted the market focus of tire mold to overseas, and its customer base has been locked into the world's largest tire manufacturing company. The goal is to achieve 30% market share of high-end customers in the next 3 to 5 years, so that the company can get rid of the impact of the domestic tire industry boom cycle.
In order to further expand the North American market and enhance the company's international comprehensive competitiveness, Julun Co., Ltd. invested and set up a wholly-owned subsidiary, Julun Holding Co., Ltd., in Delaware, the United States, and took it as the main body to acquire 75% of the equity of Northeast Mold Company of the United States. In the future, it will further enhance the international competitiveness of tire mold and rubber machinery products through localized marketing and services, It has become another sales and technical service base with global strategic significance after the headquarters of China and the Indian subsidiary.
Four aspects of upgrading into a powerful country
China's tire mold industry has developed rapidly, but it is not balanced, and the industrial structure is also unreasonable, which is mainly reflected in the large number of low-end mold enterprises, mold overcapacity, intense homogenization competition in the industry, and insufficient enterprise development potential. Although the mold industry chain has been formed, the key mold materials and mold steel still need to be imported. There is still a certain gap between the tire mold casting technology and the international level. The early development capacity of high-end molds is insufficient, but only a few enterprises have the ability to participate in international competition in the field of high-end molds. The irrational industrial structure and the concentration of low-end enterprises have formed obstacles to the development of the tire mold industry. With the adjustment of the global manufacturing pattern and the restriction of domestic industrial development factors, China's tire mold industry needs to achieve transformation and upgrading in the following four aspects:
R&D and design. China is not only the "manufacturing center" of tire mold, but also the "R&D and design" center of the world, which can lead the R&D trend of the international tire mold industry and master a number of core technologies with independent intellectual property rights.
Industry and brand. It has a complete tire mold industry system, reasonable industrial structure, large, complex, precise, high-performance, long-life mold production capacity, and several tire mold brands with strong international competitiveness, good international reputation and broad international market.
Management and service. With a complete tire mold management system and high degree of informatization, it can serve the upstream and downstream industrial chain. The tire mold industry should run through the entire life cycle of the tire manufacturing industry.
Talent and policy. There are sufficient talent reserves, a large number of high-level scientific and technological talents and management talents, as well as a large team of technical workers. At the policy level, it is recommended that relevant universities and scientific research institutes offer high-level courses in material processing and mold technology, promote the development of disciplines and specialties, and accelerate the cultivation of high-end talents with theoretical and practical abilities.
