Illig Maschinenbau GmbH & Co. KG of Heilbronn, Germany, introduced a new thermoforming line with the emphasis on speed and product quality.
In a recent demonstration, Illig pumped out drinking cups on an RDM 70 thermoforming line, running 40 cycles per minute. Also new: the RDK 90 automatic forming/punching machine.
Illig said the new, third-generation machines and tools make it possible to reach cycle times for polypropylene, which have so far been achieved only in polystyrene forming. The tighter processing range for PP requires special heating technology in automatic, roll-fed thermoformers. Heating rolls located in a closed cabinet heat the sheet uniformly.
The RDM 70 does pressure forming and punching in one station. A new PH 54 stacking device can do single-row cup stack discharge, for automatic post-processing. For speed, the turning device, with a suction box on both sides, picks up the cups from the forming machine and forwards them to a stacking cage.
Illig calls the RDK 90 the first thermoforming line designed for in-line operation and use of end packers — producing large batches in up to 55 cycles per minute. After parts are formed and punched, steel rule dies, integrated into the forming tool, separate the parts from the web.
The company's North American headquarters, Illig LP, is in Cohasset, Mass.
