PET Preform Injection Molding Machine

PET injection molding machines are intelligent forming equipment specifically engineered for polyethylene terephthalate (PET) material. They are extensively utilized in high-transparency applications such as beverage preforms, food containers, and cosmetic packaging. Their core value lies in addressing critical challenges of PET resin, including poor thermal stability, high hygroscopicity, and acetaldehyde generation.

  • Precision Injection Control

  • High-Speed Production Efficiency

  • Specialized Plasticization & Temperature Control

  • High Stability & Durability

Enhanced Power & Hydraulic System

● Incorporates upscaled motors and pumps to establish a robust dynamic framework, with hydraulics precisely calibrated to PET injection requirements, ensuring stable and controllable pressure/flow parameters.

Specialized Screw Design

● Featuring increased L/D ratio (barrel length-to-diameter) and PET-optimized shearing elements that effectively reduce shrinkage deformation while enhancing the optical clarity of PET products.

High-Torque Plasticization Motor

● Enhancing plasticization efficiency for more thorough and rapid PET material processing, driving high-efficiency production.

 

Dedicated Cooling Circuit & Ejection System

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

● Ejection System: Augmented ejection force/stroke achieves streamlined demolding for multi-cavity PET products.
