Extrusion International 5-2018

Extrusion International 5/2018 Thin-Gauge PET/PP Line „ A Welex Evolution ® sheet extrusion line from Graham Engi- neering Corporation has given custom sheet processor Pro Ex Extrusion a thin-gauge capability not generally found among cus- tom sheet houses. In 2017, Pro Ex partnered with Graham Engineering to specify a Welex Evolution sheet line that would expand its capability and capacity. Commissioned in December 2017, the dual-resin PET/PP line features a 5” (130mm) extruder with the flexibility to expand to co-extrusion. 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 indepen- dently driven, heated, and cooled. Based in Oskosh, Wisconsin, Pro Ex Extrusion is a recycler and manufacturer of custom and proprietary plastic products, includ- ing sheet, roll stock, profile, injection molding, polymeric com- pounds, and packaging technologies for several industries. The company’s sheet business comprises roll stock for thermoforming and lithography. They also work with several experienced print- ing partners to apply high-quality graphics to their products.

He says: “Many sheet houses are able to produce PET/RPET at 15-18-20 mil. The ability tomanufacture high quality polyester at 10-12-14 mil expands our capability to serve more demanding applications and gives us a capability not generally found among custom sheet houses. Adding the ability to run high quality clear and colored polypropylene on the same sheet extrusion line as thin as 15 mil truly differentiates us in the market.” J-stack configuration featuring roll-skewing and electric gap adjustment under full hydraulic load Unique technologies, innovative solutions, comprehensive technical support, high ex- pertise in all kinds of plastics applications.
