Keba system drives injection presses
Keba AG, the controller maker from Linz, Austria, is pitching its KeDrive electric drive for injection molding machines.
The KeDrive D6 drive system, made for multiaxial applications, can run an injection press. During molding, not all the drives need to be used simultaneously. The injection axis has the largest power requirement. Drives for mold movement and plastication both need 70 percent of that maximum power level, while part ejection and pressing require 25 percent.
A drive system using KeDrive D6 components feeds a central power supply unit via the common direct-current voltage link of the five inverter axis modules.

Bruckner BOPP line is sold to Dubai firm
Bruckner Maschinenbau GmbH & Co. KG of Siegsdorf, Germany, has sold a 28.7-foot-wide biaxially oriented polypropylene film line to Dubai-based Taghleef Industries, for a new factory in Sohar, Oman.
The line is running at a constant speed of 1,666 feet per minute. The Oman line can produce up to 11,000 pounds of BOPP film an hour.
This is Taghleef Industries' seventh joint project with Bruckner. The German company provided the turnkey package, including plant layout, utilities, resin-storage facilities, peripheral equipment, finished material-handling and film-recycling systems.

Macro winder can function in reverse
Macro Engineering & Technology Inc., a film equipment company in Mississauga, Ontario, has developed a reversible surface winder called Automax-SBG.
Unlike traditional gap surface winders that can wind film in only one direction, the automax-SBG features a reversible winding mode. That allows the processor to choose whether to wind jumbo rolls with the film's treated side in, or with the treated side out.
To switch winding directions, the operator simply needs to thread the film in the opposite direction around the drum and select the correct winding direction on a touch screen.
Another feature: straight-edge cut-overs that are done without fold-over, so rolls are flat and wrinkle-free all the way to the core.
The winder can handle rolls up to 4.9 feet in diameter, and film thicknesses from 0.6-16 mils.
Winding shafts are available in sizes of 3-6 inches.
It will wind materials up to 9.8 feet wide at speeds up to 656 feet per minute.

Software designed for flexible packaging
Toronto-based Plastisoft Corp. has released PS-Quote, a software program designed exclusively for the flexible packaging industry.
Using PS-Quote, makers of flexible packaging can cost and quote their products from extrusion through printing, laminating and converting. Users can construct custom or stock product specifications, including raw materials, run and scrap rates, labor and overhead costs.
The software is capable of costing film substrates with up to 10-layer blends.

New Maplan screws enhance pipe making
Extruder maker American Maplan Corp. has developed screws designed to run modified PVC (MPVC) and chlorinated PVC (CPVC).
MPVC pipe has improved toughness and impact strength needed for pipe and fittings for water distribution, air distribution and mining applications. The properties are comparable to unplasticized PVC, according to Maplan, based in McPherson, Kan.
The screw has a special flight geometry that provides optimum plastification without sacrificing output rate or an increase in melt temperature because of shear. Extruding MPVC compound presents processing issues because of the need for additional energy input for proper plastification.
Maplan said CPVC compounds can present challenges because of their thermal instability. The company's CPVC screw provides a typical reduction of melt temperature up to 15-20°F, while giving superior plastification. A reduced melt temperature significantly extends the reaction or decomposition time.
The screw also can double the time between purges and shutdowns for cleaning.

MGF feeder features multilingual operation
Maguire Products Inc. said its MGF gravimetric feeder now has multilingual operator access and full data retrieval as standard features for all molding and extrusion applications.
Languages include English, Czech, French, German, Italian, Polish and Spanish.
Another new feature, called extrusion following, automatically anticipates and adjusts for gross variations in extruder rate, such as those during changes of film rolls. That ensures accuracy of the MGF feeder while avoiding the productivity losses that happen when color metering does not keep pace with ramp-ups in line speed, said Pat Smith, vice president of marketing and sales.
Maguire Products is based in Aston, Pa.
