A Brief Introduction to Circular Die Cutting

At present, the packaging and printing technology has been updated daily and continuously. Prepress technology and printing technology have undergone one revolution at a time. Although the die-cutting technology of post-press processing is developing slowly, as the market demands continue to increase, it is constantly undergoing upgrading. With the wide use of gravure production lines and flexo printing lines in various packaging companies, a round-bore circular die-cutting technology is also becoming more and more popular for the complete completion of webs from printing, die-cutting to waste-discharging and rewinding. It is valued by people. This kind of die-cutting technology with high-precision register device and die-cut phase adjustment, which can obtain higher die-cutting precision, realizes a leap in technology on die-cut creasing embossing.
According to the different printing paper, printing can be divided into sheet-fed printing and web printing. According to the different indentation forms, the die-cutting and creasing machine has the advantages of flat pressing, round flat pressing and round pressing. After the sheetfed paper is printed, it can be die-cut by a flat-press die-cutting die-cutting machine. After the web-fed paper is printed, there are many options. After the roll-to-roll printing is completed, the die-cutting hot stamping is completed on a round press die cutting hot stamping machine. One. At present, most domestic producers use a flat sheet press die-cutting machine for production. The automatic die-cutting die-cutting and creasing machine is a flat-pressing die-cutting machine that can continuously produce without pressure, and has a large pressure and is automatically discharged. In addition to the extensive use of sheet-fed flat die-cutting machines and web-rolling die-cutting machines in foreign countries, this has prompted the wider application of circular die-cutting technology.
For the round press die cutting technology is generally divided into two kinds of pressure cut type and shear type. Among them, pressure cutting is a traditional die-cutting method and is suitable for short-lived work. The shear type represents the most advanced round press die cutting technology. The combination of the two, for the improvement of die-cutting accuracy and speed, as well as the development of multi-function and full-automatic, has a great effect on the enhancement of product reliability and stability, so domestic and foreign manufacturers are working hard to develop. . Different from flat die-cutting and die-cutting machines, circular die-cutting and die-cutting machines can be used separately as well as on-line die-cutting with web printing presses, which has the advantages of high efficiency, high speed, and more accurate die-cutting indentation.
The advantage of the round die-cutting technology is that it can produce special-shaped carton boxes and some larger size carton boxes. In the process of operation, compared with the traditional flattening and rounding flattening, not only in the speed, but also in the human and material savings are also significant progress. Of course, as an emerging technology, it is relatively more expensive in terms of technology cost and machine reconstruction. At the same time, it is required that the die-cutting technicians in the operation must be very professional in the operation of the machine in order to perform the maximum function. However, even so, it is inevitable that some unexpected factors will affect the effect of die-cutting. Such as the size of the error, the production is not smooth and so on. Therefore, it is difficult to handle it well when it is made. In addition, the advantages and disadvantages of die-cutting machines are directly related to the technical effects. Because the error of the machine is every manufacturer of the brand is inevitable. The quality of the paperboard also causes some differences in size, resulting in paper breakage and other conditions. It is only possible to achieve perfection by overcoming the above-mentioned problems in die-cutting production.
At the same time, in the selection of materials, it must be carefully considered: 1. The selection of the knife. There is a big difference between U-knife and general knives. The U-Knife is sharper, has less damage to the machine, and is more fluid when it operates quickly. Some of the round-circular press machines in foreign countries also make use of Euler's knife. 2, pressure line protection. The U.S.-designed squeegee is highly versatile, and therefore it has effectively improved the phenomenon of pressure line breakage. France's powerful sponge swarf removal effect is better and faster than the average, and these materials are on the price. It is relatively high, but it is inconsistent with the general materials in terms of its effect.
In the past, circular die-cutting technology was complicated due to the manufacturing of rotary cutters, which could not be produced domestically. The import cost was high and maintenance was inconvenient, which affected the advantages of some production lines. In 1998, a domestic company introduced a full set of round press die cutting technology and equipment to fill this gap. Circular pressure die cutting technology in the future, the development momentum is visible, in today's rapid economic development, the key to the development of enterprises lies in technological innovation. It is believed that more carton manufacturers will invest more funds to improve equipment and increase market competitiveness.
