40" Wide Sterling Co-Extrusion Sheet Line

Description

Used 40" wide Sterling co-extrusion sheet line. reconditioned in 1998-2000 to produce films of synthetic paper 4-20 mils thick. Line consists of the following:
- 3.5" Sterling 30:1 L/D extruder driven by a 125 HP DC motor with Allen Bradley series "B" SCR controller, 440 volt AC input. Extruder is electrically heated and water cooled including closed loop water cooling system and side vented (plugged) barrel. With 14/1 gearbox ratio.
- Maag melt pump currently mounted on 3.5" extruder.
- 2.5" Sterling co-extruder, 30:1 L/D with 13.351 gearbox reduction and 50 HP DC motor with SCR controller. Has electrically heated water cooled barrel with closed loop water cooling system.
- 2.5" Entwhistle co-extruder, 30:1 L/D with non-vented barrel, driven by a 50 HP Reliance DC motor with SCR control.
Each of the above extruders are equipped with 3.5" MGB Engineering screen changers with oversized 3HP hydraulic pumping system for all three changers.
