China Professional Injection Molding Making Heavy Duty HDPE Plastic Pallet Injection Mould

The working principle of injection molds is based on the thermoplastic properties of plastics and the injection pressure of injection molding machines. Firstly, plastic particles are heated and plasticized inside the barrel of the injection molding machine, forming a molten state. Then, the injection molding machine injects the molten plastic into the mold cavity through high pressure. In the mold, the plastic is cooled and solidified to form the desired shape and structure. Finally, by opening the mold, the formed plastic product is taken out of the mold.

Injection molds are widely used in the home appliance industry, such as TV casings, refrigerator liners, washing machine casings, etc. These plastic products usually require a beautiful appearance and precise dimensions, and injection molds can meet these requirements.
