——Efficiency Meets Energy Saving: Lisong Supports the Beverage Packaging Supply Chain

PET preforms are intermediate products used to manufacture packaging containers such as beverage bottles and cooking oil bottles. Their molding quality directly determines the transparency, barrier properties, and mechanical strength of the final container. Preform production places strict demands on the injection molding process and typically requires specialized PET machinery, with precise control over plasticizing temperature, injection speed, and cooling time.

Ningbo Lisong Injection Molding Technology has launched PET-specific models that incorporate multiple optimizations for processing crystalline plastics:

• A high-efficiency dehumidifying drying system, integrated with the material conveying system, prevents material degradation caused by moisture.

• A short-stroke, high-speed injection unit enhances production efficiency while minimizing material thermal degradation.

• A dedicated hot runner control system ensures consistent quality and stability in the gate area.

Practical applications demonstrate that Lisong PET injection molding machines produce preforms with excellent dimensional consistency and intrinsic quality while maintaining high output. Customer feedback confirms smooth performance in downstream blow molding processes. Moreover, the equipment offers lower overall energy consumption compared to similar products, meeting the stringent cost-control requirements of large-scale production in the beverage industry.

We also provide customized solutions—including injection unit configuration, cavity count, and cooling design—tailored to specific preform weight and output targets, delivering truly adapted system solutions for each customer.
