PET Injection Molding Machine

PET injection molding machines are intelligent molding equipment specially designed for polyethylene terephthalate (PET) material. They are widely used in high-transparency applications such as beverage preforms, food containers, and cosmetic packaging. Their core value lies in addressing critical challenges faced by PET resin, including poor thermal stability, high moisture content, and acetaldehyde generation.
  • Precise Injection Control

  • High-Speed Production Efficiency

  • Specialized Assembly and Temperature Control

  • High Stability and Durability

Optimized Power and Hydraulic System

It incorporates upgraded motors and pumps to create a powerful dynamic framework, with hydraulic components precisely calibrated for PET injection requirements, ensuring stable and controllable pressure/flow parameters.

Specialized Screw Design

It features an increased L/D ratio (barrel length to diameter) and enhanced shearing elements for PET, which effectively reduces shrinkage deformation while improving the optical clarity of PET products.

High-Torque Plasticizing Motor

Enhances plasticizing efficiency to process PET materials more thoroughly and quickly, leading to high-efficiency production.

Dedicated Cooling Circuit and Ejection System

Cooling Circuit: Accelerated mold cooling allows for rapid solidification of the PET product, enhancing cycle rates while boosting dimensional stability (±0.05% tolerance).

Ejection System: Enhanced ejection force/stroke facilitates a streamlined demolding process for multi-cavity PET products.
