1、 Basic principle of injection molding machine
Injection molding machine is a kind of equipment that heats plastic and injects it into the mold to make it cool and solidify in the mold, and finally forms the required plastic products. Its basic principle can be summarized as the following steps:
Melting of plastic particles: first, add plastic particles into the hopper of the injection molding machine. In the injection molding machine, plastic particles are heated and melted through the heating system to form a flowable plastic melt.
Injection stage: once the plastic melt reaches a certain degree of fluidity, the screw mechanism of the injection molding machine starts to rotate and press the melt into the injection cylinder. The injection system of the injection molding machine pushes the melt into the mold through high pressure.
Injection mold: the injection system of an injection molding machine injects plastic melt into a precision designed mold, which is usually composed of two parts, namely, a movable mold and a fixed mold. The injection molding machine fills the mold cavity by injecting the plastic melt into the mold.
Cooling and solidification: after the injection molding machine is injected into the mold, the plastic melt is rapidly cooled through the cooling system to solidify and form. Cooling time and temperature are key factors that affect the quality and performance of the final product.
Mold removal: once the plastic is completely solidified, the mold is separated and the molded plastic products are removed from the mold. After this process is completed, the injection molding machine can start the next round of injection process.
2、 Application fields of injection molding machine
Injection molding machines are widely used in various industries, providing an effective means to produce plastic products of various specifications and uses. The following are the main applications of injection molding machines in different fields:
