PET Thermoform Sheet Making Machine

PET Thermoform Sheet Making Machine produce flat plastic sheets or films, typically ranging from thin films a fraction of a millimeter thick up to thicker sheets several millimeters thick. They usually consist of an extruder (often single-screw for polyolefins like PP/PE or PET, but can be twin-screw for PVC or high-filled materials), a flat sheet die (often a wide rectangular slot opening), and a set of polishing rollers or calender rolls that press and cool the extruded melt into a solid sheet of precise thickness. After the cooling rolls, the continuous sheet may be trimmed at the edges and either wound into large rolls or cut into panels. Roofing sheet extrusion lines are a special category that produce panels for roofing applications – for instance, a roofing sheet extrusion line can make corrugated PVC roofing panels or multi-wall polycarbonate sheets used for skylights and shelters. These lines may incorporate forming stations to impart a corrugated profile or multi-wall structure to the sheets before cooling.
