Plastics News reporters gathered these news stories during NPE 2003, held June 23-27 in Chicago.
Sandretto introduces toggle-clamp presses
NPE 2003 marked the North American debut of two new toggle-clamp injection molding machines from Sandretto USA Inc.
Sandretto USA also announced it is selling all-electric molding presses made in Italy by Bodini Presse srl. Sandretto is the U.S. unit of another Italian firm, Turin-based Sandretto Industrie SpA.
Sandretto shared a 2,400-square-foot booth with its sister company, polyurethane machinery maker Cannon USA Inc.
One of the new toggle machines, the high-speed Mach 3, comes in clamping forces of 150-400 tons. Sandretto is targeting high-volume and technical parts that require thin walls or long flow paths.
The Mach 3 has an electric screw drive. Independent hydraulics, run by independent accumulators, drive movements for clamping and injection. The moving platen is supported with feet, ensuring alignment.
The other toggle, Series NS, is the next generation of Sandretto's general-purpose press. Available in clamping forces of 75-485 tons, the press has a compact footprint and an energy-efficient hydraulic system.
The Mach 3 and NS both come with an SEF 2000 controller.
Sandretto USA also showed a 100-ton all-electric press, kicking off its distribution deal with Bodini. Sandretto USA said it is the sole U.S. distributor of the Bodini Eledrive presses, available in clamping forces of 25-165 tons. Sandretto also will handle service.
Features of the Eledrive include generous clamp and platen dimensions and a compact machine design. Besozzo, Italy-based Bodini introduced the Eledrive at K'98, but it primarily has been sold in Europe.
Sandretto and Cannon USA both are part of Cannon Group in Trezzano, Italy.
Cooling Turbo-Screw aids foam extrusion
Plastic Engineering Associates Licensing Inc. used NPE 2003 to introduce its patented Turbo-Screw cooling screw that dramatically increases throughput in plastic foam extrusion.
Bill Fogarty, vice president of marketing, said the keys to the screw's performance are cross-flight holes that improve mixing and reduce energy use. Total energy savings amount to 12 percent in some cases, according to Fogarty.
Plastic Engineering has focused on foamed polyolefins and polystyrene in long single-screw extruders, tandem machines and twin-screw machines. At NPE, it displayed a 200-millimeter screw for tandem use.
Fogarty said he and two of his brothers co-own the firm. The company has six U.S. patents for Turbo-Screw and 50 foreign patents pending. His father, Jim Fogarty, developed the screw after four decades of experience in plastic foams and turned the technology over to his sons.
Bill Fogarty said his company has been marketing Turbo-Screw globally for three years to end users, but Plastic Engineering Associates also will discuss licensing with equipment manufacturers.
