The die-cutting tool is the core component, usually made of high-hardness alloy material, with extremely high wear resistance and cutting accuracy; during the die-cutting process, the die-cutting tool cuts the tape into the desired shape by applying a certain amount of pressure. As the key equipment to achieve cutting, the die-cutting machine ensures the accuracy and stability of cutting by controlling the movement and pressure of the die-cutting tool;
