Injection Molding Machine is a kind of mechanical equipment widely used in the plastic processing industry. It is mainly used to inject molten plastic raw materials into the mold under high pressure, and obtain various plastic products after cooling and molding. Injection molding machines are usually composed of injection units, clamping units, power units and control units. Its main functions include efficient and accurate production of large quantities of plastic parts with complex shapes and precise dimensions. According to the working principle and application field of injection molding machines, injection molding machines can be divided into manual, semi-automatic and fully automatic types, suitable for various industries such as electronics, automobiles, medical treatment, home appliances, packaging, etc. It is easy to operate, has high production efficiency and strong product consistency. It is one of the indispensable key equipment in modern manufacturing. With the development of science and technology, the precision, automation and environmental protection performance of injection molding machines are constantly improving, which can meet the production needs of different products and become one of the core technologies of the plastic manufacturing industry.
