　　Technical advantages and characteristics of die cutting products

　　At present, packaging printing technology is changing with each passing day and developing constantly. Although die-cutting technology in post press processing develops slowly, it is also constantly updated with the continuous improvement of market requirements. With the wide use of gravure printing production lines and flexographic printing production lines in various packaging enterprises, in order to realize the one-time completion of rewinding of web paper from printing, die-cutting to waste disposal, the circular die-cutting technology is also increasingly valued. This die-cutting technology with high-precision registration device and die-cutting phase adjustment can achieve higher die-cutting accuracy, which has achieved a technological leap in die-cutting indentation and concave convex indentation.

　　As the circular die cutting is line contact, the die cutting pressure is small, the equipment power is small, the stability is good, and the continuous rolling die cutting is high. During die cutting, one cylinder exerts pressure. The other cylinder is a knife die. The metal roller cutter die is processed by chemical corrosion or electronic engraving, and is mainly used for die cutting of self-adhesive labels and trademarks.

　　Advantages of circular die cutting

　　(1) High production efficiency. The printing and die cutting are connected, and the maximum speed can reach 350~400m/mln.

　　(2) Die cutting quality is good. Rotary die-cutting is line contact. Working pressure small products have good forming stability, accurate geometric shape and size.

　　(3) Die cutting precision is high. Rotary die-cutting machine is equipped with high-precision registration device and die-cutting phase adjustment device, which can obtain fairly high die-cutting accuracy. The positioning accuracy of printing, die cutting and indentation can be improved through the tension control system of web paper feeding.

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

　　(5) Wide application range. Rotary die-cutting can form a printing die-cutting production line with offset press, gravure press, flexographic printing press, etc. In addition, film and metal foil are the fastest growing packaging printing materials, which also brings new opportunities to the circular die-cutting machine.

　　(6) Save paper. The connection round pressing round die cutting adopts the roll feeding method, which does not need to leave the position of the mouth and the tip when typesetting, and can conduct continuous cross typesetting, which can save about 6% of the paper. For enterprises such as cigarette packet printing plants, the cost saved is very considerable.

　　Disadvantages of circular die cutting

　　However, the wire circular die cutting also has the disadvantage of high die cutting tool cost and long processing cycle of the circular die cutting roller. Therefore, wire circular die cutting is more suitable for the production of large quantities of long version live parts, but not for small quantities of short version live parts. Xiao Bian believes that foreign die-cutting technology is more widely used in cigarette package printing field, because foreign cigarette packages have fewer types than domestic cigarette packages, and the process is simple, while domestic cigarette packages have many brands, and the post processing process is complex, and the circular die cutting will be limited, which is one of the reasons for the slow development of circular die cutting in China.

　　Domestic market prospect

　　Although the domestic production capacity of circular die cutting technology is not high due to the complexity of tool manufacturing, high import costs and inconvenient maintenance, which affect the advantages of some production lines, with the improvement of domestic technology, many domestic die cutting equipment manufacturers have expanded the production of offline circular die cutting equipment, which is a means for die cutting equipment manufacturers to further innovate based on the characteristics of domestic packaging and printing after processing processes, Such equipment can be provided by domestic manufacturers such as Shanghai Bernell Yahua Beijing Nanfeng Seiko Tancheng New Era Machinery Shandong Linyi Eiffel Machinery. In China, the production of off-line circular die-cutting equipment is combining with the latest international technology, and the accuracy and speed of the equipment have been further improved. Therefore, many domestic joint ventures and foreign carton packaging enterprises have purchased circular die-cutting machines from domestic machinery manufacturers.

　　In addition, the domestic production of 650mm die cutting tools has made rapid progress in recent years, which has solved the problem that the original 13 cutting tools need to be sent to foreign countries for maintenance with a long cycle. Such tools are produced by enterprises in Shenzhen, Zhejiang, Shanxi and other regions. Xiao Bian believes that with the integration of the domestic tobacco industry, the centralization of brands, and the integration with international standards, there will be more large quantities of long version live parts. Circular die cutting is more suitable for the molding and processing of such live parts, and circular die cutting will usher in the spring of development.
