The ZSE-27 MAXX “direct to sheet” system from Leistritz facilitates rapid in-line compounding and production of prototype sheet samples. Benefits of direct sheet extrusion include the product having one-less heat/shear history, and economic savings inherent with bypassing the pelletization step. The following components will comprise the system:
ZSE-27 MAXX co-rotating, intermeshing, twin screw extruder:
• 52/1 L/D with modular barrels and segmented screws
• 1.66/1 OD/ID ratio for screw
• 40 kW water-cooled motor
• Q2 LSB-26 side stuffers for filler/fiber introduction
• Allen-Bradley Compact Logix L3 PLC with PanelView Plus 15-in. touch screen HMI
Gear pump front-end attachment with 20 cc/rev capacity and 5 HP AC motor
14-in. Sheet/film flex-lip die
3-Roll sheet/film system with the following features:
• (3) 8-in. diameter by 16-in. wide rolls with linear motion and individual 1 HP AC motors/drives
• Driven rotary shear edge-trimming
• Dual unwinds for extrudate lamination/encapsulation utilizing magnetic particle brakes
• Integral, center driven rewind with automatic gap control and closed loop tension control
• Air expanding chucks on rewind and unwind shafts
• Allen-Bradley CompactLogix L2 PLC with touch-screen HMI
