Because the circular die cutting is line contact, die cutting pressure is small, the equipment power is small and smooth and good continuous rolling die cutting, high production efficiency. When die-cutting, one roller exerts pressure, and the other roller is the die. Another roller is a knife mold. Metal drum die using chemical corrosion or electronic engraving method processing and become, mainly used for self-adhesive labels and trademarks die cutting. (1) high production efficiency. Printing and die-cutting in line, the maximum speed of up to 350 ~ 400m/mln.
(2) die-cutting quality. Circular pressure round die cutting is line contact. Working pressure is small product molding stability, geometry, size and accuracy.
(3) high precision die cutting. Circular pressure circle die cutting machine is equipped with high-precision register device and die-cutting phase adjustment device, can obtain quite high precision die cutting. The tension control system of web feeding can improve the positioning accuracy of printing, die-cutting and creasing.
(4) Long service life. Round pressure round die cutting rollers can be repaired and ground 3 times. After each grinding can also run 10 million revolutions far higher than other die-cutting methods.
(5) wide range of applications. Circular pressure round die-cutting can be offset printing machine, gravure printing machine flexographic printing presses and other components of the printing and die-cutting production line. And the fastest growing packaging and printing materials are film and metal foil, but also for the circular die-cutting machine to come to a new opportunity.
(6) saving paper. Line circular die-cutting roll feeding method in the layout without leaving the gripper and drag the tip of the position, and can be continuous cross-platting, which can save about 6% of the paper. For cigarette packet printers and other enterprises. The cost savings are very substantial. Although the round pressure round die cutting technology because of the complexity of tool manufacturing domestic production capacity is not high. Higher cost of imports, maintenance inconvenience, affecting some production lines to take advantage of. But with the improvement of the domestic technical level of many domestic die-cutting equipment manufacturers to expand the production of off-line circular die-cutting equipment, which is the die-cutting equipment manufacturers for domestic packaging and printing post-processing more than the characteristics of the process. Further innovation means, in the domestic... Shanghai Bernier - Yawar Beijing Nanfeng Precision Shandong Tancheng new era of machinery Shandong Linyi Eiffel machinery manufacturers can provide such equipment. Domestic production in the off-line circular die-cutting equipment is combined with the latest international technology, equipment precision and speed have been further improved so many domestic joint ventures, foreign-funded carton packaging enterprises have purchased the domestic machinery manufacturers of circular die-cutting machine.
In addition. Domestic in recent years in the 650mm die-cutting tool production progress is very fast, a good solution to the original into the 13 tools to be sent abroad for maintenance. Longer cycle of the problem. This tool in Shenzhen, Zhejiang, Shanxi and other regions have enterprises to produce. Mr. Chang Jiang that with the domestic integration of the tobacco industry, the brand centralization. As well as with international standards, there will be more high-volume long version of the live parts, circular pressure round die cutting is more suitable for this kind of live parts molding process, round die cutting will usher in the development of the spring.
