Plastic Injection Molding Machine

PRECISION PLASTIC INJECTION MOLDING MACHINES

What is a plastic injection molding machine?

Plastic injection molding machine, also known as injection molding machine or thermoplastic molding machine, is a device that heats, melts, and injects plastic particles or powder into molds at high temperatures, and then cools and solidifies to form plastic products of various shapes. Plastic injection molding machines occupy a very important position in the processing of plastic products and are widely used in various industries such as home appliances, automobiles, electronics, packaging, medical equipment, and construction.

When choosing a plastic injection molding machine, you need to select the appropriate model and specifications based on actual production needs. At the same time, factors such as energy efficiency, stability and after-sales service of the equipment also need to be taken into consideration. In general, the plastic injection molding machine is one of the indispensable and important equipment in modern production. Its application has brought huge economic and social benefits to all walks of life.

Working principle of plastic injection molding machine

The working principle of the plastic injection molding machine is to heat and melt the plastic raw materials, inject them into the mold through high pressure, and then cool and solidify to form plastic products of the desired shape. Specifically, the workflow of a plastic injection molding machine includes four stages: feeding, melting and plasticizing, injection and cooling.

In the feeding stage, plastic raw materials are added to the hopper of the injection molding machine. After being transported and compressed by the screw, the raw materials are pushed to the front end of the barrel.

In the melting and plasticizing stage, the raw materials at the front end of the barrel are heated and melted under the action of the heating ring. At the same time, the rotation of the screw pushes the raw materials to move backward, and are continuously compacted and plasticized.

In the injection stage, the screw, driven by the oil cylinder, injects the molten plastic raw material into the mold through the nozzle at high speed and high pressure. Injection pressure and speed can be adjusted as needed to obtain plastic products of different shapes and sizes.

In the cooling stage, the plastic raw materials are cooled and solidified in the mold to form plastic products of the desired shape. The length of cooling time will affect the hardness and quality of plastic products, so it needs to be adjusted appropriately according to raw material and product requirements.

The working principle of the plastic injection molding machine mainly relies on the rotation of the screw and the pushing of the injection cylinder, as well as the cooling and fixation of the mold. By adjusting parameters and optimizing the process flow, high-quality and efficient plastic product production can be achieved.
