K-Tron International plans large K lineup
At K 2007, K-Tron International Inc. will introduce a new extrusion control system, a low-rate pellet feeder and several products from Premier Pneumatics Inc., which K-Tron bought in 2006.
Pitman, N.J.-based K-Tron has continued to use the Premier Pneumatics brand name for all of its pneumatic conveying lines.
The company also will feature the new K-Vision feeder control interface, the full Bulk Solids Pump family of feeders, the Multiweigh blender and the K4G blender with integrated Premier Pneumatics vacuum receivers for refilling, a ``smart'' flow meter, the improved MT12 Micro feeder, a quick-change feeder and both single- and twin-screw loss-in-weight feeders.
K-Tron (Booth A74, Hall 10) will run a computerized demonstration of the Gravimetric Extrusion Control, which measures the throughput of the extruder and adjusts its speed to maintain the desired rate and provide consistent quality. It is designed for use with single-screw extruders in applications such as profile extrusion, cast sheet, blown film, cable coating and laminating.
The system is implemented in the KCM feeder controller and the K-Tron Smart Commander feeder operator interface for coextrusion of multiple layers.
At the Oct. 24-31 show in Dusseldorf, Germany, K-Tron also will introduce a new version of its low-rate feeder, the Micro Cone. By using a screwless rotating tube or cone, the feeder can dose very low amounts. The new Micro Cone will use KCM controls and a stepper motor. It will come in volumetric and gravimetric models.

Conforma Clad crafts protection for screws
Conforma Clad Inc. of New Albany, Ind., has introduced to the twin-screw extrusion industry its infiltration brazed tungsten carbide protection for screw elements.
The cladding is metallurgically bonded to screw flights greater than three-sixteenths of an inch. That provides tighter barrel tolerances and improved process control, according to the company.
Conforma Clad (Booth A36, Hall 12) will exhibit the technology at the K 2007 show.

Preform presses offer multilayer technology
Husky Injection Molding Systems Ltd. is offering Kortec Inc.'s multilayer technology as an upgrade to Husky's standard HyPET preform injection molding machines.
``With the Kortec-ready system, preform molders can now quickly and easily upgrade from a mono-layer system to multilayer system when the need arises,'' said John Kermet, vice president of sales and marketing for Kortec in Ipswich, Mass.
The Kortec-ready option will include a stationary platen and machine base, upgrades to the electrical and hydraulic systems, modifications to machine controls and other features not found on a standard HyPET.
Craig Reynolds, Husky's market manager responsible for barrier technologies, said the option ``provides customers with an affordable, staged entry into this growing market.''
Husky is based in Bolton, Ontario.

Low Flex 6.0 design provides for choices
Thermoforming Systems LLC of Union Gap, Wash., said an undisclosed customer has begun producing 32-ounce polypropylene soft drink cups on its first two Low Flex 6.0 thermoforming machines.
The machines have a forming area of 65 inches by 67 inches. They can run more than 90,000 of the cups an hour, running in-line with an extruder that pumps through 9,000 pounds of material an hour.
The Low Flex design allows thermoformers to use greater tonnage, widen the process window and use advanced techniques such as coining on a large-bed thermoformer.
The machine can operate with air pressure of more than 1,000 pounds per square inch to turn out containers as deep as 9 inches.
Thermoforming Solutions also offers the Version 6.0 horizontal trim press, with a heavier frame design and a four-point platen drive. That allows for a significant increase in trim tonnage, while maintaining parallel platens through strokes up to 14 inches. The press integrates design features such as servo pick feed, servo parts eject, servo adjust shut height and side trim tool loading.
Cannon introducing A-Basic unit at Utech
Cannon Group of Trezzano sul Naviglio, Italy, will introduce its A-Basic economical metering unit and the Cannon JL mixing head for polyurethane processors at the Utech North America conference, scheduled for Sept. 24-26 in Orlando, Fla.
A-Basic is a high-pressure, pump-driven metering unit. The JL mix head boasts an L-shaped head without injectors, simplifying its use and allowing for a range of outputs, according to the company. The JL stands for ``jetless.''
Company officials also will present four technical papers.

Greenerd enlarges compression presses
Greenerd Press & Machine Co. Inc. of Nashua, N.H., has expanded its line of compression molding machines, increasing clamping-force tonnages up to 10,000 tons and bed sizes to more than 240 inches.
The bigger machines are well-suited for a range of compression molding applications, such as automotive parts, electrical components, housewares and appliances, the company said.
Greenerd's machines feature a four-post design aimed at minimizing the deflection and ``lean back'' that can happen with many C-frame presses.
The design also enables the press to be loaded from all four sides, making the machine easy to integrate into production lines or work cells, according to the company.
The presses feature a cycle that evacuates gasses while a part is being cured in the mold.

Sica machine shifts pipe diameter in-line
Sica SpA, an Italian maker of downstream extrusion equipment, is touting its haul-off and cutting machine that automatically changes pipe diameter, in-line, without stopping production and with no intervention by the operator.
Sica calls it the FullAuto process. Synchronization between the extruder and the haul-offs allows for control over the extrusion speed and the position of the caterpillars.
During the transition to a different pipe diameter, upper tilting caterpillars and electric position transducers help the FullAuto haul-off automatically recognize the in-process diameter change, and the machine repositions the lower caterpillars to keep the same extrusion axis.
The pulling force remains constant during the automatic diameter switch.
The cutting machine works independently of the upstream equipment, thanks to two electromechanical measuring systems that operate automatically. One detects the change in pipe diameter; the other registers the pipe speed and setting of the cut length.
Sica is headquartered in Alfonsine, Italy.
