Color masterbatch is a highly efficient solution for coloring plastics, produced through precise pigment dispersion and compounding technology. Using a twin screw extruder, pigments and carrier resins are uniformly mixed, melted, and pelletized to ensure excellent color consistency, dispersion, and process stability. This technology is widely used in packaging, automotive, and consumer plastics, providing reliable and high-quality coloring performance in modern plastic manufacturing.

Plastic pelletizing is a key step in plastic recycling. By melting, filtering, and cutting cleaned plastic waste into uniform pellets, a plastic pelletizing machine ensures stable feeding, consistent material quality, and higher recycling value. For recycled PP and PS packaging waste, pelletizing transforms low-value scrap into standardized industrial raw material ready for efficient reuse.

Plastic coloring requires precise and consistent dispersion of pigments, not just polymer melting. Compared with single screw extruders, twin screw extruders provide superior mixing, accurate pigment feeding, and stable process control. This results in uniform color, lower pigment consumption, and reliable batch-to-batch consistency, making twin screw extruders the preferred solution for high-quality plastic coloring applications.
