A rotary die-cutter is a machine used in the printing and packaging industry to cut materials into specific shapes. It operates by using a rotating cylinder with a sharp die attached to it, which presses down on the material as it passes through. This process allows for high-speed production and precise cuts, making it ideal for creating labels, boxes, and other packaging items. These machines can handle various materials, including paper, cardboard, and plastic. Rotary die-cutters are often preferred for their efficiency and ability to produce intricate designs, making them essential tools for manufacturers looking to streamline their production processes.
