Development and Analysis of Processing Equipment Industry in China's Die and Mold Industry

After the "Eleventh Five-Year" development, China's mold industry has indeed made great progress. It has now entered the world's top position in total production. Although China is already a major producer of molds and machine tools, it is far from being a strong country. This is an indisputable fact.

The development of the mold industry, in addition to all the other necessary conditions, the improvement and progress of equipment is very critical. Mainly manifested in: the vigorous development of foreign-funded enterprises, China's mold production scale and product level has a rapid development; non-state-owned economy springing up, so that China's rapid expansion of mold production, product levels are also relatively Raise quickly. In the Pearl River Delta and Yangtze River Delta regions where Hong Kong capital, Taiwanese capital, and foreign capital are particularly concentrated, along with the rise of enterprises in machinery, electronics, light industry, building materials, communications, and office equipment, production of self-produced molds for internal support of enterprises With it a lot of development. This part of the mold production scale is about 300 to 500 billion yuan. The total scale of mold production in China has exceeded 60 billion yuan in 2005.

If the average annual increase is 15 billion yuan, the input-output ratio of fixed assets is roughly 1:1. About 60% of the investment is used to purchase new equipment for calculation. On average, about 9 billion yuan will be spent on purchasing each year. Kinds of equipment. This is an estimate of the equipment market in the mold industry. Although this equipment market accounts for only a small proportion of the total size of the machine tool industry, it cannot be said to be too small and should not be overlooked. Even if the foreign-funded enterprises mainly use foreign equipment to remove this piece, the domestic machine tool industry will still have at least 6 billion yuan in equipment market per year. If the level of domestic equipment and services are competitive, foreign-funded enterprises are also willing to purchase inexpensive domestic equipment. Therefore, it is not an exaggeration to describe the market of about 30 billion yuan during the "Eleventh Five-Year Plan" period with the word "big".

The basic requirements of the mold industry for equipment compared with other mechanical processing, mold processing has its own particularities, these particularities are: 1. Most molds need to process complicated curved surfaces on solid metal modules. With the continuous development of molds, the weight of modules will also increase, and some of them have reached several tens of tons. 2. Most molds are rectangular or rectangular in shape. They are rarely narrow and long. The main processing volume is concentrated on the mold and punch. 3. With more and more precise and complex requirements for mold products, the requirements for precision machining of molds have become higher and higher. Now, the machining accuracy of many molds has reached ±1 to 2 μm, and will soon develop to less than ±1 μm;4. With the shorter and shorter requirements of the user on the mold production cycle, mold processing must meet the requirements of high efficiency, rapidity, and a certain degree of flexibility and full-time non-stop operation at full load.

According to the above four particularities, the following basic requirements are put forward for mold processing equipment: 1. The machine tool must have good rigidity and large load capacity that can adapt to the weight of the module. 2. Workbench size to adapt to the size of the mold, suitable for rectangular or square and round, not narrow, but the height direction and its travel requires a larger space; 3. Must have high accuracy and precision retention; 4. To be able to remove the margin quickly and efficiently, and have a high degree of reliability in order to maintain continuous full-load operation; 5. In order to adapt to the complex space surface processing, and there are a large number of processing, it is required that the machine tool can be multi-axis-linked and equipped with a large-input information capacity numerical control system.

In the above, only some of the basic requirements for mold processing on equipment have been proposed, and there are still many special requirements. For example, plastics processing machines require higher speeds. However, due to the small cutting forces, the machine tools can be light-weighted to reduce costs. The research and development presses used in trials do not require high efficiency and speed, but require anti-rotational energy. In order to repair the mold; some simple processes can be used for special machines and so on. At the same time, compound processing, flexible processing, and on-line inspection are also requirements for mold processing.

Analysis of the competitiveness of domestic mold equipment Currently, domestic equipment produced by the domestic machine tool industry, except for a few high-end equipment domestic lack of independent innovation capabilities, but also difficult to meet a moment, most of the domestic technology and ability to meet, but because the machine tool industry does not pay attention This market of the mold industry and the lack of careful analysis of some special requirements for mold processing result from the research institute.

[1] [2] [3] Next page The main performance is: 1. The product has not been developed for the special requirements of the mold industry. The main structure cannot be well adapted to the mold processing, including the size and weight of the table, the rigidity and stability of the machine tool, the reliability of long-term full-load operation, high-speed, high-efficiency, high-precision, and large margins. Spatial surface processing, etc. 2. The quality of many parts and components on the equipment does not matter, especially certain electronic components, certain mechanical parts and numerical control systems, etc. 3. Due to the enterprise system, mechanism and management reasons, including the assembly quality and the overall level of service is not high, especially after-sales service can not keep up, resulting in die companies can not easily choose domestic equipment.

With respect to the equipment market for the mold industry, compared with imported equipment, domestic equipment lacks competitiveness in terms of performance, reliability, accuracy, quality, delivery time, and comprehensive service capabilities. The reasons are: First, the capacity for independent innovation is weak; second, the equipment market in the mold industry is not valued; and third, the system, mechanism, and management cannot keep up.

Take CNC machine tools as an example. In 2005, the output of CNC machine tools in China has exceeded 60,000 units. The number and level of products have made considerable progress, but their domestic market share is less than 30%. (According to data, 2004 is 26.9%) In the mold industry, I am afraid that 20% will not come. Why is this? I think there are roughly three reasons: First, there is a strong demand for CNC machine tools in the domestic market, especially for medium and low-end products, which are widely spread and easy to produce. Most machine tool factories are full of tasks, which makes many companies concerned not to pursue. High, refined, sharp, difficult varieties and high-end products; Second, most machine tool companies have weak independent innovation capabilities, and the core technologies and key technologies are less mastered. Even if they are determined to develop medium-to-high-end products, they are more than satisfied. Insufficient power; Third, although the mold industry has a relatively large equipment market, but due to the special nature of mold processing, especially the individual requirements are more prominent, mold companies are mostly small and medium-sized enterprises, ordering digital equipment is difficult to form a larger batch, Therefore, to meet the needs of the mold industry, it is indeed more difficult, and we must make great efforts, but there will be some risks, but also have the level of Caixing. In view of these three reasons, the domestic machine tool manufacturers still do not pay attention to the equipment market of the mold industry, or have no time to attend to it, and have to allow imported equipment to play the leading role.
