two stage extruder
two stage extruder

-----special combination to meet rigid plastic MB or granules extrusion needs


Two Stage Extruder(twin screw extruder +single screw extruder)

1st stage: parallel co-rotating twin screw extruder;

2nd stage: single screw extruder.

 

Parallel co-rotating twin screw extruder is designed with modular screw elements and barrels without extrusion head at the end, so the melt can drop into the single screw extruder directly. Single screw extruder will complete extrusion and pelletizing process to realize steady output of material under higher rotating speed. This kind of two stage extruder features high capacity, steady discharge etc.

According to material and processing, you can choose different pelletizing method, such as water cool strand, air cool hot cutting, water ring and underwater pelletizing or choose various molds or related auxiliary equipment for directly extrusion molding.
