The two stage extruder
Just as its name implies, consists of two extruders. It can be combined in many ways, use Jinwo as an example, our double stage extrusion line has two models: twin screw extruder+ sinlge screw extruder, and sinlge screw extruder+ twin screw co-rotating extruder. This two-stage compound extrusion system combines twin screw strong mixing, high speed with single screw low temperature, better stabilization characteristics to enhance advantages.

The application of the two stage extruder
Heat-sensitive Materials
such as PVC cable material, XLPE peroxide crosslinking material, PE low smoke halogen free resistance fuel, etc.
Carbon Black Masterbatch
If the carbon black percentage is under 40%, then our two stage extrusion line can make good masterbatch. But if the percentage is over 40%, kneader + single screw extruder will be better.

The feature of the two stage extruder
- Using twin screw high speed, high shear, and strong hybrid advantages, the materials are fully plasticized and mixed. Without the back pressure, we are possible to flexibly arrange the screws per different materials to realize optimal state of materials mixing.
- It is helpful to implement different technological processes to maximize the advantages of the equipment, and greatly improve production efficiency.
- Air-cooled granulation, eccentric water mist granulation, stretch granulation, and water ring granulation can be selected according to material properties.
