Processing Technologies International (PTi), a leading global manufacturer of high-performance sheet extrusion machinery, has announced that it is in the final stages of formalizing a commercial agreement with a leading global tooling manufacturer for the exclusive sourcing of its patented layer-flipping technology. This technology allows processors to quickly change the position of extrudates from two extruders in a coextruded structure without tedious disassembly and costly shutdowns.

PTi is a leading manufacturer of highly engineered sheet extrusion systems. This article illustrates and describes the benefits of PTi's newly introduced all-nipping roll stand for cooling and polishing sheet.

Sheet extrusion is characterised by the production of double-polished sheet which is cooled between rollers which exert high closing forces. Thinner film is produced by the casting process where the film is thin enough to be cooled only on one side by a polished roller. Thingauge double-polished sheet at about 200 microns thick is at the borderline between cast film and typical double polished sheet. This thickness threshold depends on the material being extruded and its thermal and physical properties. The production of thin-gauge sheet presents unique challenges which will be examined here.
