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.
At present, domestic progress has been made in the application of magnetic die-cutting in in-line circular die-cutting. Take Omet's dual-station die-cutting (Twn-Cut) patented technology as an example. It uses a set of magnetic die-cutting rollers to process repetitive 12- to 33-inch jobs. This technology is on a servo transmission model. Combined with the increasingly mature magnetic knife roller die-cutting technology, the cost bottleneck of the in-line circular die-cutting method is solved. Magnetic knife roller + die-cutting knife is an in-line die-cutting method that is very suitable for cigarette package printing factories. It can achieve similar effects to the overall round knife.
However, some experts believe that. Magnetic die-cutting is mainly connected to flexographic printing machines, and flexographic printing is used in the printing of high-end products such as cigarette packs. The printing quality cannot compete with offset printing and gravure printing. And the precision of the magnetic die-cutting process is not high. When printing with die-cut typesetting repeats changes in perimeter. The magnetic knife roller must be replaced. The investment in magnetic knife rollers is relatively expensive and the delivery cycle is long. Usually it takes 2 months. Development is limited.
