Congraf, a company dedicated to industrial packaging printing, located in Sao Paolo in Brazil, has purchased a Polar die-cutting system DC-11 to increase productivity in its paper label section.
The DC-11 system includes an automatic cutting machine POLAR Autocut 25 (AC 25). A pusher device on the loading table feeds the automatic cutter with pre-cut label strips. The AC 25 cuts them into label stacks. Subsequently, a swivel unit transfers the stacks to the feeder of the die-punching unit DC.
After die-cutting the label stacks, a pusher automatically transports the processed labels to the single-headed banding unit BD. Because the single-headed bander uses ultrasonic technology, preheating is not necessary. This workflow offers the performance of up to 960 bundles per hour.
According to Congraf, the transition from manual die-cutting processes to automation is expected to improve the productivity by double digits, especially in the beer label segment.
