A sheet coextrusion line from Amut in Egypt

An Amut extrusion line for PS and PP sheets to be thermoformed has been installed at an Egyptian converter. The plant reaches over 700 kg/h of total output, and produces sheets with a 1,000 mm usable width and an ABC layers configuration with a thickness range of 0.2 to 2 mm.


The Easy Feed main single screw extruder has a diameter of 75 mm and an L/D ratio of 52:1, and is based on an extrusion and feeding concept designed to feed up to 100% thin grind material, without reducing the hourly output of the plant: the result is an operator-friendly and flexible machine. The EA 48 L/D 40:1 and EA 35 L/D 33:1 co-extruders are equipped with water-cooled bushes, gravimetric dosing units and gear pumps that guarantee constant and accurate flow control.


The need for a high level of automation required by the customer is satisfied by the thickness gauge and the automatically adjusted die. The tailor-made high heat exchange vertical calender ensures a correct sheet cooling. An intermediate sheet cutting system and a 3-station winding system complete the equipment of this line, capable of producing rolls up to 1,200 mm in diameter.
