Physical diecut and magnetic diecutting performance competition

The steel alloy solid die-cutting plate has been the main die-cutting plate used for circular die-cutting in the past 20 years. The price of the die has been significantly reduced, and it has almost reached the point where carton processors do not need to think too much. The mold manufacturing and processing technology has also advanced to the point where it can be delivered within a few days. The accuracy of mold processing is getting higher and higher, and all die-cutting preparation work is completed before the mold is delivered.

Although the mold manufacturing process has enabled molds to continue to reduce costs, physical diecuts still have some deficiencies for some carton processors and certain production conditions. In order to make up for this as quickly as possible, mold makers have accelerated the development of magnetic die-cuts that use magnetic rollers to hold the die-cut.

The development of magnetic die cutting is very rapid, mainly due to its low price. A magnetic die cut is about 25% to 30% of the price of a physical diecut. Through its application in recent years, the magnetic die-cutting plate has established its position in ultra-small carton processing, and can be applied to the trial production of carton samples and test articles. Carton processors can fully use magnetic die-cutting if they can reasonably calculate the production volume of less than 8 million carton boxes per year, and the physical die-cut version is more suitable when the annual output is more than 8 million.

Here are two things to note. First, most magnetic die-cutting die-cutting processes require an auxiliary process or a waste bin, which is different from the physical die-cutting process. The solid die-cut version is equipped with an integrated pin-type discharge section, and therefore has advanced features in terms of simplicity, reliability, and processing speed. Second, the magnetic die-cutting plate cannot be re-ground after passivation of the die-cutting blade. The solid die-cut version can be repeatedly ground 3-5 times after passivation of the normal die-cutting blade.

With the application of more innovative technologies, the resistance of the carton makers adopting the sheetfed offset + flat-press die-cutting old processing mode to the new change is the greatest obstacle to the application of flexographic printing + circular die-cutting. Manufacturers of flexographic printing equipment suppliers and round press die cutting equipment have realized that based on the common long-term interests, both parties should cooperate with each other to complete the transition and transition of new and old equipment and processes as simply and smoothly as possible.
