The development prospect of injection molding machine
Looking back on 2008, the total global export of injection molding machines was US$5.46 billion, of which the German injection molding machine industry ranked first in the world, and the total export value accounted for more than 20% of the world's total export value. It is in a dominant position in the global injection molding machine competition. Italy and Japan ranked second and third respectively. The export share of injection molding machines in the United States has been declining year by year, from 9.8% 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 in Europe, America and Japan are mainly 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, the manufacturing level of China's plastic machine industry in the field of low-end injection molding machines is almost the same as that of developed countries. Coupled with the advantage of labor prices, China's low-end injection molding machine exports occupy half of the world's . In addition, in recent years, China's plastic machine 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 machines is expected to gradually expand.
As far as the global market structure is concerned, the continuous development of the global construction market will drive the demand for extrusion products such as plastic pipes and siding, which in turn promotes the growth in demand for extrusion equipment. Therefore, the global demand for extrusion equipment is expected to exceed that of other types of press products. US industrial market research firm surveys show that the US and Japan's demand for plastic machinery will re-emerge signs of recovery, and Western European market demand will accelerate growth in 2009. Prospects for sales of plastic machinery in China, India and Russia are promising. Turkey, the Czech Republic, Iran and other developing countries and regions will also gradually increase the demand for plastic machinery.
There are many manufacturers of injection molding machines in China, and according to incomplete statistics, there are more than 3,000. There are two types of injection molding machines: vertical and horizontal. According to the products produced, it can be divided into ordinary injection molding machines and precision injection molding machines. The injection volume is 18-51000g at a time; the clamping force is 30-36000kN; the processing raw materials are thermosetting plastics, thermoplastics and rubber. Thermoplastics include polystyrene, polyethylene, polypropylene, nylon, polyurethane, polycarbonate, plexiglass, polysulfone, and (acrylonitrile/butadiene/styrene) copolymer (ABS), among others. From the point of view of the processed products, there are general and precision plastic products of single color and double color.
Ordinary horizontal injection molding machine is still the leading direction of the development of injection molding machine, and 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 in the direction of combination and serialization according to market changes. , as the same type of injection molding machine is equipped with large, medium and small injection devices, which are combined into standard type and combined type, which increases flexibility, expands the scope of use, and improves economic benefits.
In recent years, injection molding machine manufacturers in developed industrial countries in the world are constantly improving the function, quality, supporting ability of auxiliary equipment, and automation level of ordinary injection molding machines. At the same time, vigorously develop and develop large injection molding machines, special injection molding machines, reaction injection molding machines and precision injection molding machines to meet the needs of producing plastic alloys, magnetic plastics, and plastic products with inserts.
Injection molding machine is one of the plastic machine varieties with the fastest development speed in China's plastic machinery and a small gap between the level and industrial developed countries. But it mainly refers to ordinary injection molding machines. In terms of most varieties of extra-large, various special, special-purpose and precision injection molding machines, some products are still blank, which is the main gap with industrialized countries.
