Processing Technologies Inc. showcased its new Revolution-series sheet extrusion system for inline thermoforming and roll stock production at NPE 2006 in Chicago.
A key feature of the Model 5000 is modulating valves for optimal chilled water consumption, said President Dana Hanson. The water system also has a quick-chill feature useful for PET. A spare water system covers potential water system malfunctions.
The rolls have motorized vertical height adjustment to allow easy and accurate positioning. The Auto-Gap servo-hydraulic computerized gap setting ensures precision. Individual roll drives allow for precise control of surface speed. The system has a 68-inch roll face and proprietary roll finish to promote sheet release.
The extruder is a 5-inch, 32-1 ratio, 300-horsepower machine with water cooling. Angled approach to the nip provides for production of resins with low hot-melt strength. Heated die lips and compound angle on the body are available for PET production. Other features include a dual-bolt continuous screen changer, a Model 90 gear pump system with static mixer and a pivoting extruder base.
Hanson said his firm has set up a sales office in Prague, Czech Republic, and is branching to other European countries. It also has lined up sales representatives for China and Mexico.
