Looking back at 2008, the total export volume of injection molding machines in the world was 5.46 billion US dollars, of which the German injection molding machine industry ranked first in the world, and the total export volume accounted for more than 20% of the world’s total exports. It is in a dominant position in the global injection molding machine competition. Italy and Japan are ranked second and third. The export share of injection molding machines in the United States has been declining year by year, and has fallen from 5.8% in 2000 to 5.3% in 2008. Japan’s electric injection molding machines occupy an important position in the world, and the share of electric injection molding machines in North America has reached about 30%. The injection molding machines of Europe and the United States mainly focus on high-tech and high value-added models such as precision injection molding machines and large injection molding machines. After years of technology introduction and technological innovation, China’s plastic machine industry in the field of low-end injection molding machines, the level of manufacturing has been similar to that of developed countries, coupled with the advantage of labor prices, making China’s low-end injection molding machine exports account for half of the world. . In addition, in recent years, China’s press industry has not only made great progress in the field of mid-end injection molding machines, but also made important breakthroughs in the field of high-end injection molding machines. The market share of China’s plastic presses is expected to gradually expand.
As far as the global market structure is concerned, the continuous development of the global construction market will drive demand for extruded products such as plastic pipes and siding, which in turn will drive demand for extrusion equipment. Therefore, it is expected that the global demand for extrusion equipment will exceed that of other types of press products. According to a survey by the US Industrial Market Research Corporation, demand for plastic machinery in the US and Japan will re-emerge in signs of recovery, and demand in Western Europe will accelerate in 2009. Prospects for sales of plastic machinery in China, India and Russia are promising. Demand for plastic machinery will also increase gradually in Turkey, the Czech Republic, Iran and other developing countries and regions.
There are many manufacturers of injection molding machines in China, and there are more than 3,000 incomplete statistics. The injection molding machine is available in both vertical and horizontal configurations. According to the products produced, they can be divided into ordinary injection molding machines and precision injection molding machines. The injection volume is 18-51000g; the clamping force is 30-36000kN; the processing materials are thermosetting plastic, thermoplastic and rubber. Thermoplastics include polystyrene, polyethylene, polypropylene, nylon, polyurethane, polycarbonate, plexiglass, polysulfone, and (acrylonitrile/butadiene/styrene) copolymer (ABS). From the perspective of processed products, there are plain and two-color general and precision plastic products.
Ordinary horizontal injection molding machine is still the dominant direction of the development of injection molding machines. Its basic structure has almost no major changes. In addition to continuing to improve its control and automation level and reduce energy consumption, manufacturers are developing towards combined serialization according to market changes. For example, the same type of injection molding machine is equipped with three kinds of injection devices: large, medium and small, which are combined into standard type and combined type, which increases flexibility, expands the scope of use and improves economic benefits.
