Since the circular die cutting is line contact, the die cutting pressure is small, the equipment power is small, the stability is good, the rolling die cutting is continuous, and the production efficiency is high. A roller applies pressure during die cutting. The other roller is the die. The metal roller die is processed by chemical etching or electronic engraving methods, and is mainly used for die cutting of self-adhesive labels and trademarks. (1) High production efficiency. Printing and die-cutting are connected in line, and the maximum speed can reach 350~400m/mln.

(2) The die-cutting quality is good. Circle die cutting is line contact. The product has low working pressure, good molding stability, accurate geometric shape and size.

(3) Die-cutting precision is high. The circular die-cutting machine is equipped with a high-precision registration device and a die-cutting phase adjustment device, which can achieve very high die-cutting accuracy. The tension control system for web feeding can improve the positioning accuracy of printing, die-cutting, and creasing.

(4) Long service life. The round die-cutting roller can be repaired 3 times. After each grinding operation, it can run for 10 million revolutions, which is much higher than other die-cutting methods.

(5)Wide range of applications. Round die-cutting can be combined with offset printing machines, gravure printing machines, flexographic printing machines, etc. to form a printing and die-cutting production line. Moreover, the fastest growing packaging and printing materials are film and metal foil, which also brings new opportunities for rotary die-cutting machines.

(6) Save paper. In-line circular die-cutting adopts the roll paper feeding method, which does not need to leave the mouth and trailing position during typesetting, and can carry out continuous cross typesetting, which can save about 6% of paper. For enterprises such as cigarette pack printing factories. The cost savings are significant. Although the domestic production capacity of circular die-cutting technology is not high due to the complexity of tool manufacturing. The cost of importing is high and maintenance is inconvenient, which affects the advantages of some production lines. However, with the improvement of domestic technology level, many domestic die-cutting equipment manufacturers have expanded the production of offline circular die-cutting equipment. This is the characteristic of die-cutting equipment manufacturers targeting domestic packaging and printing post-processing processes. Means of further innovation in the country. Shanghai Burnell Yahua, Beijing Nanfeng Precision, Shandong Tancheng New Era Machinery, Shandong Linyi Eiffel Machinery and other manufacturers can provide such equipment. The domestic production of offline circular die-cutting equipment is integrating the latest international technology, and the accuracy and speed of the equipment have been further improved. Therefore, many domestic joint ventures and foreign-funded carton packaging companies have purchased circular press dies from domestic machinery manufacturers. Cutting machine.

In addition. In recent years, China has made rapid progress in the production of 650mm die-cutting tools, which has solved the problem of having to send 13-mm die-cutting tools abroad for maintenance. A long-term problem. This kind of cutting tools are produced by companies in Shenzhen, Zhejiang, Shanxi and other regions. Mr. Chang Jiang believes that with the integration of the domestic tobacco industry and the centralization of brands. In line with international standards, there will be more large-volume long-form jobs. Rotary die cutting is more suitable for the molding and processing of such jobs. Rotary die cutting will usher in the spring of development.
