Die manufacturing to the development of two-pole precision and heavy equipment demand

Due to the important role of molds in the manufacturing industry, the mold manufacturing industry has been receiving attention and attention from industrialized countries in the world. In fact, the design and manufacture of molds has become an important area of ​​manufacturing. Due to the characteristics of the mold itself, most of the modern mold enterprises are characterized by technology-intensive, capital-intensive and high-quality labor-intensive and high social benefits. The mold manufacturing industry has become a part of the high-tech manufacturing industry. Therefore, the level of mold technology has become an important indicator of a country's manufacturing level, and it is also the core competitiveness of maintaining the advantages of these countries' products in the international market. “Now, China has become a big manufacturing country, and a big country for mold production. In 2010, sales will be close to 100 billion yuan (2008 billion yuan in 2008), mold imports will be nearly 2 billion US dollars, and will continue to be 2 billion US dollars for four consecutive years. The level of imports; mold exports close to 1.9 billion US dollars, but also with the basic level in 2008." China Die and Mould Industry Association Secretary-General Wu Bing told reporters Road.

In recent years, the level of mold manufacturing in China has increased significantly. The proportion of high-level molds represented by large-scale, sophisticated, complex and long-life molds has reached more than 35%. For example, car cover molds have been able to produce B-type vehicle molds; the accuracy of precision molds can reach 0.5μm; The precision progressive die can be used on high-speed punch presses of 2,000 to 2500 beats/min. The precision of the plastic molds reaches the micron level, which meets the needs of the development of the IT industry. The single set of tire active tools with a weight of 120T and a diameter of 4m becomes the largest. Type molds and so on. "Mold manufacturing is now moving toward two extremes, large and small. The demand for precision and heavy equipment has also increased accordingly." Wu Bingshu judges the development trend of mold and related equipment.

“Although China’s mold industry has developed rapidly over the past 20 years, it has become a major mold producing country in the world. But at the same time, we are also clearly aware of the gap between mold powers, especially in the middle-to-high-end molds. The mold industry and mold technology development attaches great importance, especially since the reform and opening up, fully affirmed the important basic position of the mold industry and technology in the manufacturing industry and the national economy.The state invested a large amount of funds to improve the manufacturing level of key molds. The major special projects include the C-class car body cover molds and other items," said Wu Bingshu.

Die processing equipment market has great potential

“Mold enterprises have a considerable amount of equipment purchases a year, and the equipment needed for mold manufacturing, especially high-end equipment, mainly depends on imports. In recent years, with the improvement of the level of domestic equipment, many mold companies have also chosen domestic machine tools.” Wu The military book said.

Statistics show that in 2009 China's machine tool consumption reached 19.8 billion U.S. dollars, which is more than one-third of the world's machine tool market share, accounting for 35.7% of the world's machine tool output value, and nearly 6 billion U.S. dollars worth of imported machine tools. Among them, the high-speed, high-efficiency, precision, compound, flexible, green, and all-manufacturing measurement unit manufacturing equipment is still the procurement direction for China's mold industry technology upgrade. The heavy load, large-volume program, and square table structure design and the With the detection and control technology, high programming resolution of the CNC system, and high-level servo control software and hardware environment are the key to ensure the precision mold manufacturing. Ultra-precision mirror milling machines, nano-milling compound centers, ultra-precision CNC lathes, etc. have also been used for mold making.

When referring to the current situation of China's mold processing equipment market, the Wu Bingshu introduced that the high-end mold processing and manufacturing equipment and measurement equipment in Japan, Europe and the United States occupy a monopoly position. The reason is that it is inseparable from the high quality of their products, but also with them. The strategy for the Chinese mold market is relevant. Their demand for the mold market is an active service. They cooperate with the mold users to develop the mold-specific functions of the machine tools and to customize the functions. Korean machine tools and machine tools in Taiwan have a very good price/performance ratio in mid-range models, and therefore they also occupy a certain market share. In the aspect of mold processing, because some of the materials used in the molds are superhard materials, the tooling requirements for the tooling are also very high. It is required that the cutting tools can cut materials above HRC60. The Armed Forces Book says that for modern, high-precision, high-efficiency, high-reliability tools, such as cemented carbide and ceramics, super hard tool materials can consume approximately 1.2 billion yuan in the amount of tools, of which 80% to 85% are dependent on imports. Tools used for tool making account for more than 90%. High-precision cutting tools for five-face machining and complex motions still use overseas products as the main purchasing target for the mold industry.

High-precision processing equipment

According to the introduction of the Wu Bingshu, the mold is a single piece of production, which has the characteristics of dependence on specific users, and its flow characteristics are that each mold product is complex, the unit price is high, the product is provided according to the order, and the combination of innovation and modification according to the user's requirements is designed. Install and debug to the user. Modifications and adjustments in the entire process make it more important to have timely monitoring at all times. This has special requirements for mold processing equipment and measuring equipment. At present, the key development direction of mold processing is no map production, single-piece high-precision parallel processing, and less humanized unmanned processing. CNC machine tools are required to meet high speed, high dynamic accuracy, high rigidity, thermal stability, and high reliability. Networking and its accompanying control system, various advanced softwares for the integrity of the machine tool, and most importantly, the three-dimensional mold surface machining pays special attention to the dynamic performance of the machine tool.

“In the manufacturing process, mold costs account for about 10% of product costs. When manufacturing competition becomes fierce, reducing costs will be the first to bear, and mold costs will have to be reduced accordingly. Therefore, mold companies hope to improve equipment automation by reducing processes. To increase efficiency and reduce costs, another important requirement that manufacturing companies place on mold companies is that molds must be promptly delivered, so mold companies need advanced production management models, coupled with high-efficiency processing equipment to meet this requirement.” Wu The Bingshu said that the mold enterprise's demand for efficient and timely equipment manufacturing is one of the most important factors in its procurement.

Although the output of CNC metal-cutting machine tools in China continues to grow, the import of high-end and special-purpose machine tools, such as gantry machining centers, CNC milling machines, CNC horizontal lathes, CNC grinders, and CNC punch presses, which are heavily purchased by the mold industry, continues to grow rapidly. With the development of mold manufacturing to two extremes, as well as the current mainstream trend of machine tool manufacturing in the world, such as high-speed, compound, intelligent, and environmental protection, mold manufacturing also places higher requirements on equipment and industry. The design and manufacture of moulds require the common development of the machine tool industry. Only when all aspects are coordinated and developed can real progress be achieved.
