Skin-foam-skin – espansione fisica PE
Triple layer physically foamed PE extrusion allows high foaming degree. The physical expansion is achieved by a gas injection unit controlled by the line supervision.
Main technical features:
- Drawing machine with conductor pre heater
- Main extruder TRF.60 30D or TRF.80 30D especially designed for gas injection and two auxiliary extruders TR.30 24D for inner skin and outer skin, V inclined
- Nitrogen injection unit for the constant gas injection at controlled pressure for even foam structure
- Fixed-centering triple layer crosshead suitable for PE physical foaming
- Efficient and controlled cooling gradient trough with integrated haul-off unit
- Automatic dual take-up for high speed line
