Twin Screw PVC Extruder Machine

A twin screw extruder is a machine consisting of two intermeshing, co-rotating screws mounted on splined shafts in a closed barrel. The screws are tight and self-wiping, which eliminates stagnant zones over the entire length of the process section. This results in high efficiency and perfect self-cleaning.Twin-screw extruders are broadly classified based on the direction of rotation of the screws, either corotating (both screws rotating in the same direction) or the counter-rotating (screws rotating in the opposite direction). Further, they can be categorized as intermeshing and non-intermeshing screws.Twin-screw extruders are broadly classified based on the direction of rotation of the screws, either corotating (both screws rotating in the same direction) or the counter-rotating (screws rotating in the opposite direction).
