Product Overview

The double-screw color masterbatch granulator is a co-rotating parallel twin-screw extrusion granulation machine, classified as a custom-made product with no fixed price; it is tailored according to the customer’s production capacity requirements. This equipment integrates plastic recycling, compounding and modification, and functionalization into one system, 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 leading brands, it boasts low failure rates and long service life, delivering stable production efficiency for customers, helping enterprises enter high-end downstream markets, and expanding their profit margins.

Key Features

The co-rotating parallel twin-screw extruder itself possesses three core characteristics: First, outstanding mixing performance—its powerful shear mixing capability ensures thorough blending of different materials, guaranteeing uniform and stable modification results; second, excellent self-cleaning properties—during operation, the machine automatically cleans the screws and barrel, minimizing material residue and preventing cross-contamination between batches; third, flexible modular configuration—allowing adjustments to equipment settings based on specific material systems and processing needs, accommodating diverse types of material processing. Building on these features, this double-screw color masterbatch granulator further offers several exclusive advantages: strong co-rotating twin-screw mixing delivers superior modification effects, enabling seamless integration of recycling and modification processes without requiring multiple sequential steps; a multi-stage vacuum degassing design thoroughly removes volatiles and impurities, effectively eliminating moisture, volatile substances, and contaminants to ensure consistent pellet quality and appearance; flexible adaptability to fillers, tougheners, colorants, degradables, and other processing requirements, meeting the production needs of various product types; and core components sourced from top-tier brands, resulting in low failure rates, extended service life, reduced downtime and maintenance costs, and enhanced production continuity.
