Air cooling hot-face cutting system for Two stage plastic polymer extruder
Two Stage Extrusion Group
HS CODE: 8477.2010
Two stage extruder mode, Standard type of 2 stages of extrusion group is equipped twin screw plastic extruder on the first stage, and the 2nd stage is single screw extruder, like TS50/D120, TS65/D150, TS75/D180, TS95/D200 and over; but we have different type of two stage plastic extusion machine group:
1) Twin screw extruder in 1st stage, and single screw extruder in 2nd stage:
50/120；65/150; 75/180; 95/200;
2) Single screw extruder in 1st stage, and twin screw extruder in 2nd stage
120/50; 150/65; 180/75; 200/95 (or 220/95);
3) Single screw extruder in 1st stage, and twin screw extruder in 2nd stage
120/120; 120/150; 150/150; 150/180 (or 150/200);
This machine extrusion group is used for:
1) heat sensitive material, like to say PVC cable, cross-liked material, & Etc.;
2) high percentage added filler, CaCo3 (Calcium Carbonate) powder, BaSo4(Barium Sulfate) powder, Talcum powder, black carbon and Etc.
The high-speed of twin screw extruder is for material melting, compounding, plasticizing and extrusion into 2nd stage: single screw extruder;
The 2nd stage: low speed of single screw plastic extruder is for material’s temperature controlling and extrusion to match the designed output capacity and quality demands.
The representative material of this extruding group machine is PVC cable granules, high percentage of CaCo3 Fillers making;
