PROFILE AND PIPE EXTRUDERS

Stronger drives and longer processing units exhibit a higher throughpu t per revolution making higher production rates of extruders possible without changing screw speed. The production volume per machine and th e line speeds have increased considerably. At the same time, melt qual ity has improved. In coextrusion, there is another potential for savin gs when foams are used as the middle layer or when low cost materials are placed in the profile surfaces that are hidden from view.
