Confident of the improvements in its third-generation thermoformers, Illig Maschinenbau GmbH & Co. of Heilbronn, Germany, is showing its RDK 90 machine for tray and lid-type production at its NPE2009 booth, S46025.
At NPE 2003, Illig displayed the forerunner RDK 80, which had 800-millimeter-sheet feed.
Everyone was impressed with that machine but they said it was too small for the U.S. market, said Thomas Stahl, who heads up sales support for Illig.
The RDK 90 is the largest of Illig's automatic pressure forming lines, for widths up to 900mm and index length of 700mm.
Illig has worked on various optimization features for its third-generation machines, and has achieved improved cycle speeds with the use of servodrives, the company said. The RDK 90 performs at a speed of 55 cycles per minute.
The RDK 90 is being shown with both forming and punching operations, making amorphous PET fresh-food trays using a 16-up tool. Illig's new ThermoLine control allows the operator to optimize and control processes.
The unit has been designed for both in-line sheet extrusion and off-line roll-fed, as shown during NPE demonstrations.
Illig also is highlighting its high-efficiency stacking system with two-axis double handling. Stacking heights of up to 600mm are possible with the optional stacking and discharge conveyor, the firm said.
