The die-cutting process of the self-adhesive die-cutting machine is a commonly used process for packaging printed products. It is a molding process that uses a die-cutting knife to assemble a die-cutting plate according to the design requirements of the product, and under the action of pressure, the printed products or other circular packaging blanks are rolled and cut into the desired shape or cut marks. The indentation process is to use a wire cutter or die to press lines on the sheet metal through pressure, or to use a rolling wheel to bend and shape the sheet according to a predetermined position. Usually, the die-cutting and indentation process is the process of combining the die-cutting knife and the indentation knife into the same template, and simultaneously performing die-cutting and indentation processing on the die-cutting machine, abbreviated as die-cutting. The main process of die-cutting indentation is as follows: plate loading → adjusting pressure → determining rules → pasting substrate and auxiliary materials → pressure testing die-cutting → formal die-cutting indentation → waste cleaning → finished product rolling or cutting into pieces → counting and packaging.
