Extruder
1. single screw extruder
The single screw extruder is an important component in extrusion of polyolefin production. The concept of long L/D and two stage unique design ensure high plasticization, low temperature plasticization. It has following features.
-High throughtput rates
-Low melt temperatures
- Good melt homogeneity
-Wide range of processing applications
2. twin-screw extruder
(1) parallel Twin-Screw Extruder
Parallel Twin-Screw Extruder Compared with traditional biaxial reduction box of parallel twin-screw extruder, the torque output of triaxial linkage increases by 50%.
Design of vertical reduction box improves transmission efficiency. Compared with traditional horizontal reduction box, it can increase by 15%.
Integral reduction box uses the latest gear material and technics, with its high-efficiency transmission realizes super-quiet running.

(2) Conical Twin-Screw Extruder
The conical twin-screw extruder is an important component in extrusion of PVC production. High quality conical twin-screw extruder and advance and unique screw with effective plasticization and the science design ensure high efficiency extrusion of PVC.
The ideal of flexible plasticization ensure the good quality of PVC pipe, profile, sheets, etc;
Dependable and the external cycling temperature control system of two stage screw core confirm the production of high quality PVC production in deffernet prescription;
With computer control system ensure the machine running stable and good production.
