Neue Herbold offers PET bottle granulator
Neue Herbold GmbH has developed a heavy-duty granulator for PET bottles.
The SM 800/2400 has a rotor diameter of 32 inches and a working width of 8 feet. A V-type rotor- and stator-knife configuration is combined with Neue Herbold's double cross-cutting system to ensure good size reduction with very few fine particles in the final granulate.
The company is based in Sinsheim, Germany. Its U.S. operation, New Herbold Inc., is in Sutton, Mass.

Paper firm licenses cooling technology
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.

Rofin-Sinar debuts highly focused lasers
Rofin-Sinar Technologies Inc. of Plymouth, Mich., is introducing its laser-welding technology for joining plastics parts, called StarWeld Diode.
The product family includes the HQ series of highly focused lasers and powerful, high-speed lasers under the HP series. The power spectrum ranges up to 150 watts, depending on the application.
In StarWeld Diode equipment, two rotating mirrors move the diode laser beam across the workpiece.
The diode modules use a patented principle of ``beam shaping,'' which Rofin-Sinar claims guarantees a high-quality beam.
The lasers can do contour welding. That means the laser moves via an axis system or a robot over the counter of a part. That allows the welding of components of almost any size, the company said.
Another available method is called quasi-simultaneous welding, which means the laser is moved very quickly across the part several times. Because plastics have low thermal conductivity, the welding path heats up gradually and evenly, so that the entire area melts at nearly the same time.

Toman spin welder unveiled at show
Toman Tool Corp. introduced its 2080 spin welder in February at the Medical Design and Manufacturing West show in Anaheim, Calif.
The welder features a new touch-screen control interface for setting up the weld time, weld distance, hold, teach position and deviation.
The spin welder can weld parts as large as 6 inches in diameter.
Toman Tool is based in Viroqua, Wis.

Cannon Group offers mixing heads for PU
Cannon Group said its AX mixing head for polyurethane can process six components, including water-based additives and low-viscosity isocyanates based on toluene diisocyanate, with high-pressure recirculation.
Cannon of Milan, Italy, designed the AX for foaming car seats.
The TDI stream can be injected at low pressure. Cannon said that minimizes the risk of leakage in the dosing circuit. Several pure ingredients are kept separate, avoiding cross-contamination, up to the moment of injection, and the AX makes it possible to operate each stream on demand.
The mixing head makes it possible to tailor foam properties for each seat on a molding line.
Cannon USA is based in Cranberry Township, near Mars, Pa.
