Cup with Lid Molded and Packaged
Designed for extra high speed, the KTR 6.1 Speed thermoforming plant from Kiefel GmbH in Freilassing, Germany, produces cups at 45 cycles per minute and is fitted with shaping plugs that are powered by linear motors. The resulting adjustable high pre-stretching speed is claimed to have a positive effect on material distribution and processing speed. Following the forming and punching operation, the Kist vertical stacking unit also processes thin-walled cups without the need for brushes or rubber.
The domed lids to fit the cups are produced by Kiefel’s Speedformer KMD 78 Power. The thermoforming plant works with a mold developed and built by Bosch Sprang B. V. in Sprang-Capelle, Netherlands. To meet the demands placed on the lids in terms of sealing and quality (e. g. central position of drinking hole), forming is done in a combined positive/negative process. What is more, this forming/punching mold combines circumferential trimming by means of steel rule cutting, and in-place trimming for the drinking hole. The waste produced by hole punching is removed automatically. Producing directly from a film roll, the thermoforming machine is fitted with a printing station and a tipping stacker. The printing station permits 2-color digital printing with a resolution of 360 dpi. The tipping stacker enables the products to be removed at an ergonomically convenient height. Optionally, the machine can be supplemented with a bag packager that packages the thermoformed products hygienically and conveniently. Before packaging, a camera system sorts out the molded parts with poor quality.
