PET Transparent Bottle Flakes Recycling Pelletizing Machine

Product Overview

The PET transparent bottle flakes recycling pelletizing machine is a customized low-temperature extrusion pelletizing equipment specially developed for PET bottle flake waste. It has no fixed price and is custom-made according to the customer’s production requirements. The equipment adopts a single-screw extrusion process, paired with a segmented precision temperature control system and a multi-stage vacuum degassing structure. Operating within a low-temperature range of 240–270°C, it completes material melting and plasticization while minimizing PET thermal degradation and preserving the material’s characteristic viscosity. Subsequently, through a multi-stage high-precision filter die, fine impurities are removed, and finally, high-purity PET recycled pellets are produced via water-cooled strand cutting or underwater pelletizing. These pellets can meet the reuse requirements in various applications such as spinning and injection molding, making this machine the core equipment for the resourceful recycling of PET bottle flakes.

Technical Principle

This equipment operates based on a single-screw extrusion process and is compatible with PET bottle flake raw materials that have been cleaned and dried. Equipped with a segmented precision temperature control system, it can accurately maintain the processing temperature within the low-temperature range of 240–270°C. While achieving the melting and plasticization of PET bottle flakes, it significantly reduces thermal degradation of the material, effectively preserving its characteristic viscosity. The accompanying multi-stage vacuum degassing structure efficiently removes residual moisture and low-molecular substances from the material, preventing defects such as bubbles and pores in the pellets. After passing through a multi-stage high-precision filter die, fine impurities are eliminated, with a filtration accuracy of up to 150 mesh. Finally, depending on the requirements, either water-cooled strand cutting or underwater pelletizing can be selected, ensuring uniform appearance and stable performance of the finished pellets.
