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 platen and platen working surfaces of the horizontal flat platen printing slotting die cutting machine are both in a horizontal position, and the lower platen is driven by a mechanism to press upward towards the platen for die cutting and indentation. Due to the small stroke of the press plate of a horizontal die cutting machine, it is difficult to manually put in or take out cardboard. Therefore, it is usually equipped with an automatic paper feeding system, whose overall structure is similar to that of a single sheet offset press. The entire machine consists of an automatic cardboard input system, a die cutting section, a cardboard output section, electrical control, mechanical transmission, and other parts, and some also have automatic cleaning devices. The horizontal flat die cutting machine works safely and reliably, with a high degree of automation and production efficiency. It is an advanced model among flat die cutting machines.
