Often our clients stand before the choice of purchase one or twin-screw extruder. Main designer  of the largest plant on the production of extruders Audrey Kong told about advantages of twin-screw extruders before single-screw: "Powdery compositions, foremost, mixtures of PVC, processed on twin-screw extruders, i.e. compositions do not require granulation, that diminishes the cost of feedstock and thermal loading on it. The effective degassing and plastication of material is provided at processing, high homogeneity of fusion, quality of the finished goods gets better. The productivity of twin-screw machines can arrive at very large sizes inaccessible for the single-screw extruders of near sizes"..
