A two cascade extruder machine is used for efficiently processing materials like plastics and rubber, especially complex formulations or high-viscosity substances. It has two screw systems: the first stage preheats and mixes the material, while the second stage completes the plasticizing and extrusion. This results in better precision, improved mixing, and uniform material distribution. It’s commonly used in the production of plastic products, pipes, films, and pellets.

Features: Combine the high speed and extensive mixing of processing and the low speed, low temperature, and low shear of single screw processing; Ideal for compounding of heat and shear-sensitive materials.
