Single Screw Extruder Machine

Single-screw extruders are used extensively in the plastics industry for melting polymers, incorporating additives (for example fillers, colouring pigments, stabilizers) and delivering a homogenized melt at high pressure to a die prior to shaping processes. A screw extruder is a type of mixer which moves the components through a cylinder using a screw which turns. Small plastic pellets are fed into the hopper of the screw extruder where they are conveyed through the extruder by the rotating screw.
