Sheet extrusion

With sheet extrusion, plastic granulate is molten and forced through a forming die to become a thermo-elastic sheet. After cooling, the sheet is rolled up. With this technology, polypropylene (PP) and polystyrene (PS) are processed. 

The technology of the plant is designed so as  to produce multi-layer sheets, offering the advantage of using recycled material in the middle layer. This technology is also the basis for numerous other procedures.
