Ridat Co. of London, which makes thermoforming machines, is launching a versatile, high-speed pressure forming machine designed for large volumes of basic plastic products such as cups, tubs, containers, plant pots, lids and trays.
One model, the 1610 APF, can produce more than 15,000 yogurt cups an hour, running a nine-cup mold at 28 cycles per minute.
The pressure formers incorporate in-tool cutting and automatic stacking. For the complete line, the machines have a maximum forming area of 16 inches by 10 inches. Cycle speeds run between eight and 50 cycles a minute.
The roll-fed material passes under a multizone heater into the tool, where it is formed and then trimmed. A blast of air clears finished products from the tool, and the skeletal waste is wound onto a rewind unit, all automatically.
The new Ridat machine spreads the heating over six index pitches, with seven heaters across the web at each station. The temperature of each zone is controlled by a microprocessor-monitored thermocouple.
