Introduction to Extrusion - Dynisco
www.dynisco.comTWIN SCREW EXTRUSION Twin screw extrusion machines or, twin screw extruders, are the simplest example of multi-screw machines (Figure 2.). The two screws may rotate in the same direction (co-rotation) or they may rotate in opposite directions (counter or, contra-rotation). The flights of the screws may intermesh or they may not intermesh.

Single screw versions are most common but twin or triple screw extruders may be used for comp lex products such as cable sheathing where they may be several layers of compound (co-extrusion). Screw extruders can be either hot fed, with warmed pre-mixed rubber, or cold fed.

The first number states how many screws the machine has, the second number speci-fies the screw diameter in millimeters (mm) and, the third number specifies the effective screw length as a multiple of the screw diameter. In the example
