The following items were covered by Plastics News reporters Bill Bregar and Tom Ford from Plastics Fair Cleveland, held June 13-15.
Toshiba Machine Co. America showed four new midsized injection presses and two redesigned controllers - both part of the company's ISG Series of machines.
The new machines have clamping forces of 114, 142, 185 and 243 tons. ISG machines feature two new controllers, the S10 liquid crystal display and the V10 active matrix color with touch screen.
Toshiba of Elk Grove Village, Ill., said ISG machines take up about 20 percent less floor space than the ISF line that they replace.
Toshiba said its new controllers have advanced visual technology and make automatic corrections, such as heat adjustments and material flow, when the injection press moves outside preset parameters.
ACE robot well-suited to low-ceiling plants
Auxiliary equipment maker AEC Inc. showed a new traverse robot and a new PS Series of 2-and 3-ton portable water chillers.
Called the Phaser Series, the telescoping, vertical-arm robot has a three-axis motor drive. The robot is designed to handle payloads up to 22 pounds on injection molding machines with clamping forces of 75-700 tons.
AEC said the telescoping arm is suited for molders with lower ceilings, or those needing clearance for overhead cranes. AEC of Wood Dale, Ill., displayed the Phaser 1150 in Cleveland.
AEC/Application Engineering's portable PS Series chillers feature a compact footprint meas-uring 22 inches by 31 inches. Other features include scroll compressors that AEC claims have 50 percent fewer moving parts than conventional compressors and brazed plate evaporators for efficient, compact operation.
PS units are air-cooled. Water-cooled PCSW units arealso available.
Buzz around town: Mini-Jector 'Wasp'
After Glenn Frohring sold Newbury Industries Inc. in 1993, he founded Mini-Jector Machinery Corp. of Newbury, Ohio, offering a pint-sized plunger machine, called the Model 45 ``Wasp.''
In Cleveland, Frohring displayed his new machine with a reciprocating screw, the Model 55. The table-top vertical-clamp screw machine has a maximum shot capacity of 1 ounce. It has a 2-horsepower hydraulic unit that operates on 230-volt, single-phase power.
Screw speed, back pressure and injection filling rates are adjustable. Screw suck-back is a standard feature.
Mokon introduces dual-zone Duratherm
The Mokon Division of Protective Closures Co. Inc. said the new dual-zone version of its Duratherm water temperature control system has a vertical design that saves space.
The unit occupies less than 4 square feet of floor space and has two independent zones of control. Each operating zone features a horizontal brass heater canister with a copper heating element and a stainless-steel diverter that forces water through a specific path.
Buffalo, N.Y.-based Mokon said that design permits greater water velocity and turbulence, resulting in more efficient heat transfer, less scale buildup and longer heater life.
Syscon-Plantstar updates software
Syscon-Plantstar, a division of Syscon International Inc., announced a new set of tool change displays for its latest Version 2.11 Focus-2000 software for computer-integrated manufacturing.
The feature gives maintenance and setup people the ability to control setup time and downtime caused by mold changes.
Focus-2000 incorporates MS-Windows in its real-time production control and process monitoring software. The software is used to build a schedule of tool changes.
Another Syscon International division, Syscon-Controlstar, introduced a new controller for extrusion machines, called Farex SR. It controls extrusion of sheet, pipe, blown film, wire and cable, medical tubing and compounding.
The companies are based in South Bend, Ind.
S. Korean firm Yudo enters U.S. market
Yudo Co. Ltd., a South Korean manufacturer of hot-runner systems and robots, exhibited at its first U.S. trade show.
Yudo can deliver hot-runner systems in two weeks after the company receives drawings, said company spokesman George Huff. The systems come with an unconditional performance guarantee.
Yudo, based in Seoul, is a significant hot-runner supplier in Korea and Japan, Huff said at the company's booth. In addition to hot runners, the company makes robots sold by the Japanese company Star Automation.
The firm's U.S. representative is Hymat-Yudo Inc. in Englewood Cliffs, N.J.
Spirex offers two software packages
Screw and barrel manufacturer Spirex Corp. of Youngstown, Ohio, has developed two Windows-based software packages for injection molding plants.
``The Maintenance Professional'' is a maintenance and inventory control package that includes an auxiliary equipment module. The price is $2,999 for as many as 100 machines.
``The Molder's Technician'' includes part cost estimating, part weight calculation, molding data, resin properties, troubleshooting and machine setup. It costs $799.
ContraBend helps end roll deflection effect
New Castle Industries showed a reverse deflection chill roll for extruding thin sheet or coextruding.
A patent is pending on the ContraBend. The New Castle, Pa., company said the design eliminates the effect of roll deflection with any combination of roll diameter and face length.
Roll deflection causes convex-shaped sheet, distortion that can cause problems with thin cap layers in coextruded products.
Firm designs analog output process alarm
Dynisco Instruments of Sharon, Mass., showed a new analog output process indicator.
Model 140 is a flexible instrument design that is easy to use, Dynisco said. The operator can program an alarm that provides a warning in case of a power failure. Dynisco Instruments is a unit of Dynisco Inc., also of Sharon.
Van Dorn Demag opens service certer
Van Dorn Demag Corp. has opened a 50,000-square-foot customer service center on the west side of Cleveland, minutes from Cleveland Hopkins International Airport.
Customers can get to the building easily to pick up parts and equipment. Van Dorn Demag of Strongsville, Ohio, also will use the building to make its HP Series of hydraulic injection molding machines, in clamping forces from 275-700 tons.
Also at the Cleveland show, Van Dorn Demag announced an agreement to sell its injection molding machines jointly with robots made by Wittmann Robot & Automation Systems Inc. of Torrington, Conn. Van Dorn Demag's parent, Mannesmann Demag, has a similar arrangement with Wittmann in Germany.
Conair Jetro shows its Sure-Cut cutter
Cutting profile and pipe different sizes can be a complex and time-consuming task, if cutting speeds must be altered.
Conair Jetro, a division of Conair Group based in Franklin, Pa., introduced the cutter.
Robert Bessemer, Conair Jetro development director, said the Sure Cut-brand cutter features a blade mounted on a large-diameter flywheel, which is positioned below the piece to be cut, instead of above, as in some downstream extrusion cutting machines.
``This is a patented process, which allows the machine to cut different-sized profile and pipe at different rates, without time-consuming changes,'' according to Bessemer.
The cutter can accommodate seven different profile sizes, from 21/4- to 51/4-inch rounds, and 2- to 4-inch square or rectangular pieces.
The blade also can be heated for greater precision cutting, and is self-lubricating.
