KRAUSS Maffei says it has supplied a pipe extrusion line to the Tyco Electronics plant in Otterbrunn Germany.
According to Krauss Maffei, the two companies have been in consultation since June 2009 working on a solution for the production of heat-shrink tubing for insulating cable connections.
Krauss Maffei says it has supplied a line headed by two single-screw extruders, a KME 45-36 B/R and a KME 60-36 B/R, and a Vac GE 90K x 24D rubber extruder. All critical system components, including the rubber extruder were integrated into a C5 system controller.
The company claims the tubing produced on the line has an insulating elastomer inner layer, a heat shrinkable insulating middle layer, and an electronically conducting heat shrinkable outer layer.
Following extrusion, cross-linking takes place and the tubes are stretched to about four times their initial diameter. In the field, the tube section is positioned over a cable connection and heated.
Krauss Maffei says the heat causes the outer and middle layers to shrink together moulding the tube around the structures which need to be sheathed, to ensure a perfect insulation.
