When corrugated cardboard is produced into corrugated boxes, it needs to be cut according to the size of the cardboard. This process is carried out using a die-cutting machine. The die-cutting machine is mainly used for some corresponding non-metallic materials. Apply a certain pressure through the stamping plate to cut the printed product or cardboard into a certain shape. It is an important equipment for post-printing packaging processing and molding. In the process of die-cutting, the edges of the corrugated cardboard need to be cut flat.
