Plastic injection molding machine It is a kind of equipment widely used in manufacturing industry, which is used to inject molten plastic materials into molds to form plastic products of various shapes and sizes. Its working principle is simple and efficient. The key steps of its working process will be introduced below.
First, the plastic injection molding machine needs to load solid plastic particles or granular materials into the hopper. These plastic particles will be sent into the heating cylinder through a conveying system, such as a screw or a piston. In the heating cylinder, plastic particles are heated and gradually melted to form molten plastic.
Next, the molten plastic will be pressed into the entrance nozzle. The nozzle is a part connecting the heating cylinder and the mold, and its role is to control the flow of molten plastic. When the plastic enters the nozzle, it will go through a series of pressure and spiral movements to ensure uniform plastic flow.
Once the molten plastic enters the nozzle, it will be injected into the prepared mold. The mold is designed according to the shape and size of the required product, and usually consists of two and a half molds. When the two halves are closed, they form a sealed chamber in which molten plastic is injected.
After injection into the mold, the molten plastic begins to cool and solidify. The cooling time depends on the type of plastic used and the thickness of the product. Once the plastic has completely cooled, the mold will open and the molded plastic will be taken out of the mold. This process can be manual or automatic, depending on the type and configuration of the injection molding machine.
In addition to these basic steps, the plastic injection molding machine is equipped with various control systems for monitoring and controlling temperature, pressure and other parameters of the injection process. These systems ensure the stability of the injection molding process and the consistency of product quality.
Lian Sheng Horizontal injection molding machine To sum up, the plastic injection molding machine realizes the production of plastic products by injecting molten plastic into the mold, cooling and curing. Its working process is efficient and reliable, making mass production of plastic products easy and economical. With the continuous progress of technology, the application of plastic injection molding machines in the manufacturing industry will continue to develop and create more high-quality plastic products for us.
