A rotary die cutter is a machine used in manufacturing to cut materials like paper, cardboard, and plastic into specific shapes. It operates by using a rotating cylinder with sharp edges, known as a die, which presses against the material as it moves through the machine. This process allows for high-speed production and precise cuts, making it ideal for creating packaging, labels, and other products. These machines are commonly used in industries such as printing and packaging. The efficiency of a rotary die cutter can significantly reduce production time and costs compared to traditional flatbed die cutting methods. This technology is essential for businesses that require large volumes of custom shapes and designs.
