It is mainly used for die-cutting, creasing, and hot stamping operations on some non-metallic materials, self-adhesive stickers, double-sided tapes, electronics, mobile phone pads, and trademarks, cartons, and greeting cards in the product packaging and decoration industry. It is an important equipment for post-printing packaging processing and forming. Its principle is to use a template carved from a steel knife, a hardware mold, a steel wire, or a steel plate, and apply a certain amount of pressure through the stamping plate to cut the printed matter or cardboard into a certain shape.
