Product Overview

The double-screw masterbatch pelletizing machine is a co-rotating parallel twin-screw extrusion pelletizing equipment, classified as a customized product with no fixed price; it will be tailor-made according to the customer’s production requirements. This equipment integrates plastic recycling, compounding and modification, and functionalization into one, featuring excellent high-shear mixing performance. It can produce high-quality modified recycled pellets and functional masterbatches in a single step, meeting the needs of various plastic processing applications. Equipped with core components from top-tier brands, it boasts low failure rates and long service life, enabling customers to achieve stable production efficiency, helping enterprises enter the high-end downstream market, and expanding their profit margins.

Key Features

The co-rotating parallel twin-screw extruder itself possesses three key characteristics: first, outstanding mixing performance—its powerful shear mixing capability ensures thorough blending of different materials, guaranteeing uniform and stable modification effects; second, excellent self-cleaning ability—during operation, the machine automatically cleans the screws and barrel, reducing material residue and preventing cross-contamination between batches; third, flexible modular configuration—allowing adjustment of equipment settings based on different material systems and processing needs, adapting to various types of material processing. On this basis, this double-screw masterbatch pelletizing machine also offers several exclusive advantages: strong co-rotating twin-screw mixing delivers superior modification results, enabling one-stop completion of recycling and modification processes without the need for multiple sequential steps; multi-stage vacuum degassing design thoroughly removes volatiles and impurities, effectively eliminating moisture, volatile substances, and contaminants from the material, ensuring stable pellet performance and appearance; flexible adaptability to fillers, tougheners, colorants, degradables, and other process requirements, meeting diverse production needs; core components sourced from leading brands, resulting in low failure rates, long service life, reduced downtime and maintenance costs, and enhanced production continuity.
