Extruder for wood/plastic composites.

The Cincinnati Milacron TC96 conical twin-screw extruder for the production of wood/plastic composites (WPC) is capable of outputs of up to 2600 lb/hr. According to the company, unique compression and low-shear mixing capabilities enable high fiber loading (up to 70%) and a broad material-processing range. The TC96 delivers a homogenous melt from blends of natural and synthetic fibers, heat-sensitive and shear-sensitive thermoplastics, recycled plastics, coupling and nucleating agents, pigments, and other additives.

The TC96's large-diameter screws--202 mm tapering to 96 mm, with 30:1 L/D ratio (based on the discharge diameter)--utilize feed zone surface area for faster, more uniform heat transmission from screws to material. Tapered screw design allows a larger feed zone for "fluffy" material and applies a natural compression during processing, which results in more effective wet-out of the wood flour. Deep flight channels and tight intermesh clearances between the conical screws make the mixing of material more efficient while reducing shear forces.
