Die-cutting is a cutting process for the post-processing of printed matter. The die-cutting process can make printed matter or other paper products into die-cutting blades for cutting according to pre-designed graphics, thereby making the printed matter The shape is no longer limited to straight sides and right angles. Traditional die-cutting production uses a die-cutting knife to form a die-cut plate according to the pattern required by the product design. Under the action of pressure, the printed matter or other plate-shaped blanks are rolled into the required shape or cut mark. The creasing process uses a creasing knife or creasing die to press out line marks on the sheet through the action of pressure, or uses a rolling wheel to roll out line marks on the sheet so that the sheet can be bent and formed according to the predetermined position. . Usually the die-cutting and creasing process is a process in which the die-cutting knife and the creasing knife are combined in the same template, and die-cutting and creasing are performed simultaneously on the die-cutting machine, which is referred to as die-pressing.

Die cutting technology:

1. Flat die cutting:

Flat die cutting, that is, the entire die is placed vertically and fixed on the same horizontal plane , the die-cutting process is completed through vertical pressure on the plane.

2. Round die-cutting:

Since round die-cutting is line contact, the die-cutting pressure is small, the equipment power is small, the stability is good, and continuous rolling die-cutting improves production efficiency. high. A roller applies pressure during die cutting. The other roller is the die. The metal roller die is processed by chemical etching or electronic engraving methods, and is mainly used for die cutting of self-adhesive labels and trademarks.

3. Others:

Magnetic die-cutting roller and integral die-cutting roller are two forms of circular die-cutting tools. Magnetic die-cutting has been widely promoted and applied abroad. It can die-cut at a high speed. The die-cutting roller has high processing precision and good flatness. The die-cutting plate is easy to disassemble and can process any pattern. The advantages of the die-cutting plate are very obvious. Therefore, the further development of magnetic die-cutting technology is a major breakthrough for circular die-cutting technology.
