The continuous development and progress of the society, the continuous advancement of the construction of a harmonious city, the gradual deepening of the concept of a harmonious society, and the increasing demand for safety have greatly promoted the development of the injection molding machine industry. The current Chinese injection molding machine industry is in the state of the end of the Warring States period . The current development trend of the injection molding machine industry is also becoming clearer.
It has more than 50 years of history since the introduction of the screw-type plastic injection molding machine with technological innovation in the 50s. At present, 80% of the engineering plastics industry uses injection molding. In recent years, due to the increasing demand for injection products in industries such as automobiles, construction, household appliances, food, and medicine, the development and improvement of injection molding technology has been promoted. The sales of plastic machinery in my country in 2000 was about 7 billion yuan, about 85,000 in terms of the number of units, of which about 40% were injection molding machines. From the perspective of major producing countries such as the United States, Japan, Germany, Italy, and Canada, the output of injection molding machines is increasing year by year, and it accounts for a large proportion of plastic machinery.
