The working principle of the die-cutting machine is to use the die-cutting knife, steel knife, hardware mold, steel wire (or the template carved from steel plate) to apply a certain pressure through the embossing plate to roll the printed matter or paperboard into a certain shape. If the whole print is pressed into a single graphic product, it is called die-cutting; If you use steel wire to press out traces or leave bending groove marks on the printed matter, it is called indentation; If the Yin and Yang templates are used and the mold is heated to a certain temperature, the pattern or font with three-dimensional effect is hot printed on the surface of the print, which is called bronzing; If one base material is used to cover another base material, it is called bonding; Excluding genuine products, the rest is called waste discharge; The above can be collectively referred to as die cutting technology.
