Co-Rotating Parallel Clamshell Barrel Twin Screw Extruder for Masterbatches

Working Principle of a Color Masterbatch Extruder

1. Raw Material Input:

   • Material Preparation: The color masterbatch extruder starts by receiving pre-processed plastic resins and colorants. Plastic resins typically include polyethylene (PE), polypropylene (PP), or polystyrene (PS), while colorants are additives used to impart color to the plastic.
   • Material Feeding: The raw materials are fed into the extruder through a feeding mechanism, such as a screw feeder, which ensures an even supply of materials into the extruder's feed zone.

2. Melting and Mixing:

   • Screw Melting: Inside the extruder, the twin screw (or single screw) rotates under heated conditions, melting the raw materials. The rotation of the screws not only pushes the molten plastic forward but also provides strong shear and mixing action.
   • Uniform Mixing: The twin screw extruder offers superior mixing capabilities, using complex screw rotations and mixing actions to ensure that the colorants and plastic resins are thoroughly and uniformly mixed, resulting in consistent masterbatch quality.

3. Pelletizing and Cooling:

   • Extrusion and Pelletizing: The molten plastic is extruded through a die to form continuous strands or “filaments.” These filaments are then cut into uniform pellets by a pelletizing system.
   • Cooling and Solidification: The cut pellets are rapidly cooled and solidified through a cooling system to maintain their shape and size after molding. Common cooling methods include water baths or air cooling.

4. Finished Product Output:

   • Product Collection: After cooling, the masterbatch pellets are screened and sorted to remove any non-conforming particles. The final product is then collected and packaged for further use or sale.
