China's mold manufacturing level has greatly improved, which should drive the demand for advanced processing technology and equipment. The production scale of China's mold industry now accounts for nearly 10% of the world's total, ranking third in the world, behind Japan and the United States. With the rapid development of China's mold industry, the demand for processing equipment such as machine tools has greatly increased, and higher technical requirements have been imposed on machine tool enterprises.
As we all know, molds are produced in a single piece and have specific users. The process is characterized by participating in the design of the product (mold part). Each mold product is complicated, the processing volume is large, and the unit price is high.
Especially in the manufacturing process of the mold, it is necessary to design a combination of innovation and modification in accordance with user requirements. It is also necessary to continuously modify and adjust the entire process of installation and commissioning. Its timelyness is extremely important. Special requirements were raised. At present, the key development direction of mold manufacturing is three-dimensionalization of mold design, analysis and manufacturing; mold software functions are integrated, networked, and intelligent; moldless production of molds; single-part high-precision parallel processing; few people and no one 化 加工。 Chemical processing. CNC machine tools are required to meet the requirements of high speed, high dynamic accuracy, high rigidity, thermal stability, and high reliability. The supporting control systems have individual characteristics, and various advanced software implements and complies with the overall operation of the machine tool.
Electrical processing machine tools are important equipment for mold processing. Since more than 80% of electrical processing equipment is used for mold processing, most domestic and foreign electrical processing equipment companies develop electrical processing equipment for the needs of the mold industry. In 2007, China imported 3336 sets of electrical processing equipment, and the average price of a single imported electrical processing machine tool was 80,000 US dollars, which is similar to the average price of imported vertical machining centers. Korean machine tools and Chinese machine tools have a good price-performance ratio for domestic molds. Businesses have great appeal.
Industry experts believe that with the development of molds to a higher level, special requirements for processing equipment include: First, the increasing size of molded parts and the high productivity of parts require a mold with multiple cavities, resulting in increasingly large molds and large tonnage. Large molds can reach 100 tons, a mold with hundreds of cavities and thousands of cavities. The mold processing equipment must have a large workbench, increase the Y-axis and Z-axis travel, and have a large load, high rigidity, and high consistency; the second is As the hardness of mold steel materials increases, thermal stability and high reliability of mold processing equipment are required. Third, for complex cavities and multi-functional composite molds, as the shape of the part is complicated, the design and manufacturing level of the mold must be improved. Multi-functional composite molds with multiple grooves and multiple materials formed or assembled into components in a set of molds require a large number of processing programming programs, comprehensive cutting capabilities and high stability for high-depth cavities, and increased processing difficulty; Fourth, the refinement of mold processing makes the complex and efficient of processing equipment more attractive. High-speed milling has many advantages such as the ability to process hard materials, stable processing, small cutting force, and low temperature deformation of workpieces, which make mold companies pay more and more attention to high-speed machining. Fifth, the high-precision machining of three-dimensional surfaces of molds has proposed high dynamic accuracy performance. It is required that high speed and high precision can only be achieved with the combination of high rigidity, thermal stability, high reliability, and high quality control systems of the machine tools. Sixth, the combination of processing technology and green product technology has been incorporated in the procurement of equipment by enterprises. Within the scope of consideration; seventh, the composite application of multiple measurement technologies, high-speed measurement and its reverse engineering has become the development direction of promoting mold participation in product development and design technology.
Related agencies announced that in 2007 China's output of CNC metal cutting machine tools reached 123,200 units, an increase of 32% over the previous year, but most of them were economical CNC machines. Among the imported 7.07 billion US dollars and 107,700 machine tools, high-end and special-purpose machine tools such as gantry machining centers, CNC milling machines, CNC horizontal lathes, CNC grinders, and CNC punches, which have been required by the mold industry, have occupied a considerable proportion, and the number has been keep increasing.
CNC milling machines increased by 75.5% year-on-year, with the largest increase in imports, followed by gantry machining centers, which increased 48.7% year-on-year, and these two types of equipment are just hot spots in the mold industry.
The enthusiasm for investment in equipment for the mold industry is also invested in CNC electric machine tools, horizontal (vertical) machining centers, laser processing equipment, and measuring machines. We know from the relevant statistics of the customs that the country ranking of CNC machine tools imported by China in order of quantity is Japan, China, South Korea, Italy, and the United States, which is consistent with the procurement situation of the industry companies learned by China Mould. of.
The level of China's mold production technology and equipment is still relatively low, and a large amount of advanced equipment is needed. At present, foreign-funded enterprises mostly use key equipment for mold processing that originates in Japan, Europe, and the United States; private enterprises have undergone the original accumulation of the startup stage, and as the scale continues to expand, mold orders have been extended to a higher level, and lower-level manufacturing equipment has also been purchased from the past , Upgrade to Japan, Europe and the United States mold processing equipment. Nowadays, Korean machine tools are more and more applied in China's mold industry; with the improvement of domestic CNC machine tools, they have begun to be selected by some mold companies.
Industry experts believe that the reason why Japanese, European and American machine tools will occupy a monopoly position in China's high-end mold processing and manufacturing equipment and measuring equipment is not only inseparable from their product quality, but also related to their strategy for the Chinese mold market. They often adopt an active service strategy, cooperate with mold users to develop and develop mold-specific functions and tailor-made functions for machine tools, and they have changed from production and sales suppliers of machine tools to service providers that provide complete solutions to users. In this regard, domestic machine tool companies need to be strengthened.
The ratio of the fixed asset investment to the growth of the mold industry in the mold industry is about 1: 1 on average. Some strong companies can invest 1: 1.5 or even 1: 2. Among the investment in fixed assets, the investment in mold processing equipment is above 80%. The total domestic machine tool consumption in 2007 was about 14.5 billion U.S. dollars, equivalent to more than RMB 100 billion. Then the sales growth of 15 billion yuan in the mold industry in 2007 meant that the demand for mold processing equipment of about 15 billion yuan accounted for the consumption of machine tools. More than 15%, and the investment of mold enterprises is long-term continuous, so the market demand for huge processing equipment brought by the development of mold industry cannot be underestimated.
It is also worth noting that today mold companies use molds as a carrier and actively exploring the production of mold parts is an important production method. There is a strong demand for mold companies to purchase parts and equipment. In 2007, China produced 173,000 forming equipment, of which 3,000 were CNC forming equipment; 3,844 imported forging and stamping equipment, and 4,671 other forming equipment; mold companies purchased forging and forming equipment, plastic forming equipment, and die casting equipment to manufacture mold peripherals The equipment and mold extension industry has formed one of the industry's development directions.
The experts in the mold industry pointed out that the level and capability of mold manufacturing has become an important indicator of national innovation ability, and the quality of mold manufacturing equipment is directly related to the level of mold technology. Therefore, I hope that domestic machine tool companies can pay attention to this market with great potential and provide more high-level processing equipment for the Chinese mold industry.
