Double-stage extrusion unit

The two-stage extrusion unit is composed of two extruders in series, which creatively distributes the extrusion processes such as solid conveying, melting, dispersion, distribution, exhaust devolatilization, pressure building, pumping, etc. and chemical units such as crosslinking, foaming, grafting, block, polymerization, etc. to the two extruders. It has the advantages of high product quality, high output, low energy consumption, and long machine life. It is especially suitable for the production of heat-sensitive materials and extrusion of complex processes.
