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

During the working process of injection molds, temperature, pressure, and time are key parameters. The appropriate temperature can fully plasticize the plastic while avoiding deformation caused by mold overheating; Appropriate pressure can ensure that the plastic fills the mold cavity, forming a complete product; A reasonable time ensures that the plastic is fully cooled and solidified in the mold to achieve ideal product quality.

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.
