Performance and Features Summary
The core advantage of this line is its integrated high-efficiency venting system, which completely eliminates the traditional pre-drying and crystallization steps for PET materials. This not only dramatically simplifies the production workflow but also significantly reduces both capital investment and energy consumption, offering a more streamlined and efficient startup solution.
Segmented Co-rotating Twin Screws: The precise screw configuration enables gentle yet efficient plastication and mixing, minimizing the viscosity loss of PET resin during processing to preserve its inherent superior properties.
Symmetrical Thin-Wall Calender Rolls: The reinforced cooling structure ensures rapid and uniform sheet cooling, which is critical for increasing line speed and improving sheet flatness and crystallization consistency.
Equipped with a multi-component gravimetric dosing system, it allows for precise control over the ratio of virgin material, recyclate, and functional masterbatch. This provides great flexibility for cost optimization and custom material formulations. The advanced automation control system guarantees consistent thickness and production stability throughout the entire process from extrusion to forming.
