Sheet extrusion

Sheet Extrusion

In the simplest form of sheet extrusion, plastic granules (possibly including additives) are fed from the extruder hopper along a heated cylinder by a rotating screw, melted & homogenized and conveyed to the sheet die. Depending on the application, there are a number of variations including the number and rotation of the screws, the screw and cylinder geometry and the structure. The die itself can be fed by several extruders extruding different thermoplastics, (for example recycled materials) resulting in layered or concentric co-extrudates. The extrudate is then cooled via chill rolls and transported to slitting and winding stations. Thermoforming can also take place in-line.

For the production of sheet products, FKuR’s portfolio includes a variety of biodegradable as well as partially or fully biobased solutions.
