MDO line is tailored to niche applications
Dr. Colin GmbH of Ebersberg, Gemany, has developed a machine-direction-orientation line that can make pilot-plant amounts of film or a small production line for niche applications.
The MDO 600 S stretch film line can process 660 pounds of film an hour.
One of Dr. Colin's long-standing customers, optical films maker Kolon Industries Inc. of Gumi, South Korea, has been running the first MDO 600 S for a year for material development and to optimize the settings of its production machinery.
Dr. Colin has designed the machine clean room production, needed for optical film, so a wall can separate everything from the material-metering area past the extruder and up to the die, from the rest of the equipment.
The angle at which the molten film from the slot die strikes the casting roll can be adjusted over a range of 45 degrees.

Future Design touts oscillating air ring
Mississauga, Ontario-based Future Design Inc. said its new air ring gives users choices: You can start with a standard air ring and, at any time, change the same air ring to a manual profiling air ring, then to a fully automated profiling air ring.
Both the manual and fully automated system can be fitted to oscillating and/or rotating dies.
Future Design officials believe this is the first automated profiling air ring that has the ability to oscillate and/or rotate.
The electronic control network of the ring has been designed to work gauge monitoring systems supplied by various original equipment manufacturers.

Greiner introduces energy-saving system
Greiner Tool.Tec GmbH of Nussbach, Austria, the Greiner Competence Center and Gruber Extrusion GmbH have developed the vacuum energy-saving system, which cuts energy costs in half for profile extrusion, using speed-controlled vacuum pumps.
The energy-saving system is integrated into the calibration table.
“The combination and the special design permit better efficiency for dry calibration and for vacuum cooling tanks,” said Leo Weiermayer, chief technology officer of Greiner Tool.Tec.
Greiner said extruder motors and vacuum pumps in calibration tables consume most of the energy in an extrusion plant.
The system can be retrofitted onto existing downstream equipment, and it is compatible with new tooling systems available on the market.
