Pipe extrusion: Internal cooling system boosts productivity


Plastics pipe extruders are offered a new tool to help increase their lines' efficiency when processing polyolefins. Developed and manufactured by KraussMaffei Berstorff, this new internal pipe cooling (IPC) system is said to dramatically reduce the initial cost and space requirements for a new pipe extrusion line, while also helping increase the productivity of already-installed pipe extrusion lines.

KraussMaffei Berstorff is the extruder manufacturing business unit of plastics processing machine maker KraussMaffei (Munich, Germany). The IPC system sucks ambient air through the center of the pipe at high speed, counter to the haul-off direction, by means of a side channel compressor. IPC, used in addition to conventional external water cooling in vacuum tanks and cooling baths, cools the moving pipe gently from the inside....
