Hemu Precision is specialized in the twin screw extrusion technology. The co-rotating extrusion units are used for compounding materials where thorough mixing is important. Co-rotating twin-screw extruders usually have modular configurations, which makes the equipment quite flexible for adapting to changing applications and material properties.
Modular barrels and screws can be assembled in any combination to provide plasticizing raw material feeding, ventilation, or gas extraction. The co-rotating intermeshing screws are arranged in parallel and are self-cleaning. Screw geometry can be adapted to individual applications. The co-rotating twin-screw compounding lines are widely used for the production of plastics compounding, powder coatings, food cereals, snacks, aquatic feed and pet food.
All types of screw elements include kneading blocks, mixing elements and conveying elements.
