A typical single screw extuder. The electric
motor can be driven at a wide range of revs/min.
Today it is accomplished using variable speed DC
or AC drive systems. This particular machine is
equipped with screw cooling, vacuum venting for
processing moisture sensitive plastics such as PC
and PET. Not shown is subsequent process
machinery such as pipe-, blown film- and
sheet-extrusion dies and other processrelated
machinery. Examples of such special machinery is
presentet in the next slides.
