Switzerland: Foil die-cutting module for existing plant
Durrer received an order from a Swiss company to develop a new die-cutting module for an existing film processing system. The company is active in the security printing sector. Therefore, highest precision was required.
The task was challenging, for several reasons: The system should punch six holes simultaneously, i.e., in one working step, in a very thin PET film of 20 to 40 μm thickness. The holes have a diameter of three millimetres. The cutting gap was supposed to be very narrow. Finally, a very high punching quality and a long product life were required.
Durrer acted as generalist and took over the complete development, design, and documentation. Our solution was a punch with prismatic grinding. This ensures results meeting all requirements.
