The working principle of PET injection molding is primarily based on the physical properties and processing characteristics of thermoplastics.
When PET granules are heated to a molten state, they soften and flow, forming a continuous liquid stream. This liquid stream is injected into the mold through a high-pressure injection unit, where it cools and solidifies inside the mold.
This process allows for adjustment of pressure and speed as needed to achieve different product shapes and sizes.
PET injection molding machines typically feature a large injection weight and a powerful power source configuration to meet the demands of efficient injection molding of PET plastics.
