The die-cutting methods of the circular press circular carton printing slotting die-cutting machine are generally divided into hard cutting method and soft cutting method. Hard cutting refers to the hard contact between the knife and the surface of the pressure cylinder during die cutting, which makes the die cutting knife more prone to wear. The soft cutting method is to cover the surface of the pressure cylinder with a layer of engineering plastic. During die cutting, the cutter can have a certain amount of cut in, which can both protect the cutter and ensure complete cutting. However, the plastic layer needs to be replaced regularly. Due to the continuous rotation of the drum during the operation of the circular press circular carton printing slotting die cutting machine, its production efficiency is the highest among various types of die cutting machines. However, die-cutting plates need to be bent into curved surfaces, making them more cumbersome, costly, and technically difficult. Therefore, circular die-cutting machines are commonly used in mass production.

The circular press flat carton printing slotting die cutting machine is mainly composed of a reciprocating planar platen and a rotating cylindrical pressure cylinder. During the working stroke, the platen moves forward to perform die cutting and indentation on the cardboard; When returning to the stroke, the platen returns backward, and the working surface of the pressure cylinder does not contact the die cutting plate. This type of die-cutting machine can be divided into several types according to the different rotation conditions of the pressure roller in a working cycle, such as stop rotation, first rotation, and second rotation. The forward and reverse rotary press die-cutting machine is a simple type, and its forward and reverse strokes can be working strokes.
