Marshall and Williams Plastics, a division of Parkinson Technologies Inc., recently added a new Leistritz twin screw extruder to its Lab/Pilot Line Facility. This is in addition to the existing four single screw extruders with a total capability of casting five layers. Use of the twin screw extruder will allow customers to compound and cast in-line at one facility. The benefit of compounding in-line versus off-line is the production of a higher quality material with a more controlled process at a reduced cost. With a world-class pilot plant facility, Parkinson offers complete flexibility for plastics sheet/film extrusion and orientation research and development. The pilot plant is actively used by resin manufacturers and material processors to conduct product development programs and produce marketing samples for a broad array of materials.
