PET Transparent Bottle Flake Recycling Pelletizing Machine

Product Overview

The PET transparent bottle flake recycling pelletizing machine is a customized low-temperature extrusion pelletizing device specifically developed for PET bottle flake waste. It has no fixed price and is custom-made according to the customer’s production requirements. The equipment employs 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 achieves material melting and plasticization while minimizing PET thermal degradation and preserving the material’s characteristic viscosity. Subsequently, a multi-stage high-precision filter die removes fine impurities, and the final product—high-purity PET recycled pellets—is obtained through either water-cooled strand cutting or underwater pelletizing. These pellets meet the reuse requirements of spinning, injection molding, and other applications, making this machine the core equipment for resource recovery from PET bottle flakes.

Technical Principle

This equipment operates on a single-screw extrusion principle and is compatible with cleaned and dried PET bottle flake raw materials. Equipped with a segmented precision temperature control system, it can precisely regulate processing temperatures within the low-range of 240–270°C. While achieving PET bottle flake melting and plasticization, it significantly reduces thermal degradation, effectively preserving the material’s characteristic viscosity. Its accompanying multi-stage vacuum degassing structure efficiently removes residual moisture and low-molecular substances, preventing defects such as bubbles or voids in the pellets. After passing through a multi-stage high-precision filter die, any remaining fine impurities are eliminated, with filtration accuracy reaching up to 150 mesh. Finally, depending on requirements, users can choose between water-cooled strand cutting or underwater pelletizing to ensure uniform appearance and stable performance of the finished pellets.
