Plastic Engineering Associates Licensing Inc. of Boca Raton, Fla., has licensed its Turbo-Screw cooling screw technology for cooling extruded polystyrene foam sheet to a $3 billion paper company.
The customer reported a 37 percent throughput increase, and it expects even greater gains after it installs a larger cooling tower for the plant's water supply.
Plastic Engineering Associates would not identify the customer, nor would it say how many firms have licensed the Turbo-Screw. But Vice President Bill Fogarty said the firm has sold more than $5 million worth of Turbo Screws since licensing began in 2000.
His father, James Fogarty, invented the Turbo-Screw and other technologies in PS foam during a 40-year career. Better cooling is the key advantage of the unusual design, which uses square holes, shaped like windows, that go all the way through the screw flights along the entire length of the screw. Used in the secondary screw, which handles cooling of the foam, the windows help propel foam outward to the barrel wall, where the cooling takes place.
The Turbo-Screw can be installed as a replacement for any conventional foam cooling screw. The major markets are PS foam sheet for clamshell and other food packaging, and insulation.
