A Welex Evolution sheet extrusion line from Graham Engineering Corp. has given custom sheet processor Pro Ex Extrusion a thin-gauge capability that Graham says is not generally found at custom sheet houses.
Pro Ex, of Oshkosh, Wis., specified a Welex Evolution line that would expand its operation.
Commissioned in December of 2017, the dual-resin PET/plypropylene line features a five-inch extruder with the flexibility to expand to coextrusion. The J-stack configuration features roll-skewing and electric gap adjustment under full hydraulic load, followed by a unique arrangement of auxiliary cooling rolls. Each roll is independently driven, heated and cooled.
Pro Ex Extrusion is a recycler and manufacturer of custom and proprietary plastic products, including sheet, roll stock, profile, injection molding, polymer compounds and packaging for several industries. Its roll stock goes into thermoforming and lithography.
