Vertical injection molding machines are one of the most widely used types of machines in the world and are the main export products of Chinese presses. However, for a long time, China's injection molding machine industry has a serious import and export profit deficit, mainly due to the lack of skills of the injection molding machine. With the acceleration of the active domestic process in China, the injection molding machine quickly provided foreign professional Chinese with a high level of skill and support and skill upgrades to keep pace with the world. The first part is improved from the skill level, from the non-active or semi-active injection molding machine to the full automation, but also very quickly, I believe that will soon become this policy.
The vertical injection molding machine chain is one of the fastest plastic machinery types in China, and it is relatively small compared with developed countries. But mainly refers to the common type of injection molding machine. In most types of large (5-gallon Pet Preform), special and fine injection molding machines, some products are still blank, which is the first distance from industrial developed countries.
From the 1950s to the introduction of technological innovations, screw-type plastic injection molding machines have been around for more than 50 years. Currently in the engineering plastics industry, 80% of injection molding. In recent years, due to the increasing demand for injection molding products in the automotive, construction, home appliances, food, and pharmaceutical industries, the development and progress of injection molding technology has been promoted. China's plastic machinery sales reached 7 billion yuan in 2000. I remember that about 85,000 units were controlled by the unit, which is about 40% of the injection molding machine. From primary producers such as the United States, Japan, Germany, Italy, and Canada, the output value of injection molding machines is increasing every year, accounting for the largest proportion of plastic machinery.
Over the years, China's injection molding machine business has developed by leaps and bounds. The production of injection molding machine products has met the needs of the domestic market, and the proportion of exports has increased year by year. However, from the perspective of skill level, all the skill levels of China's injection molding machine products are not high, and there is still a certain distance from foreign injection molding machine products, and the industry needs to be upgraded.
With the rapid development of injection molding machine technology and technology, the requirements for self-initiation are getting higher and higher. Professional experts expect full support from injection robots. The robotic arm will make an important contribution to the completion of the injection molding machine career.
Traditional injections are subverting
china pet preform manufacturers want to achieve this transformation, the entire industry needs to make breakthroughs in the following two aspects. First, focus on the capture of precision injection molding, micro injection molding, and micro injection molding. At present, there is still a big gap in the injection molding industry in terms of molding accuracy, shape and position tolerance, surface quality, precision molding speed and intelligent injection molding. In the servo motor equipment, the transmission mechanism includes the transmission screw, the slider and the tooth. Article, in terms of manufacturing precision and overall precision still can not meet the needs of intelligent injection molding, need to rely on imports.
Active exploration is needed in low pressure injection molding and micro foam molding processes. Second, the control system, including machine control accuracy and on-line monitoring system of the mold system, as well as independent intelligent control, including product inspection and identification systems and smart injection requirements still have a big gap.
