Amut Group supplies Turkish customer with hybrid extrusion line

Equipment company says its extrusion line can produce multilayer, reinforced membranes in a single step.


Amut Group reports that it has improved the performance of waterproofing membranes through its unique single step extrusion process. The company offers extrusion lines producing waterproofing membranes and able to process a variety of thermoplastic materials. The company says these materials feature improved technical performance and physical features.

According to Amut Group, its technology allows for flexible production, since different materials can be processed on the same line. In addition, the company says its line can produce multilayer, reinforced membranes in a single step, by means of reinforcing elements laminated among the layers to enhance the mechanical resistance of the finished product. The technology also allows for support base lamination.

The company says it has recently supplied a large Turkish consumer with its hybrid extrusion line, capable of producing flexible polyvinyl chloride (F/PVC) or thermoplastic membrane (TPO), three layers of thermoplastic material and thickness ranging from 1 to 3 millimeters.

According to Amut Group, no screw change is required, as the design of the extruder’s screws is suitable for both materials. The total output of the line is 1,800 kilograms per hour for F/PVC and 1,250 kilograms per hour for TPO.

The company says the extruder’s double-inlet calendar allows a “sandwich” geometry in a single step, with external layers, an inserting or laminating of polyester or glass fibre reinforcement, and a fleece-back coating.

The line is also equipped with a thickness gauge measuring device, high accuracy winder unit to produce custom and jumbo rolls, and a programmable logic control system to control all running operations of the line.
