The characteristics of wire round die cutting technology

In recent years, with the large-scale introduction of foreign gravure production lines and flexographic printing production lines, as well as the maturing of domestic gravure production lines and flexographic printing production lines, matching wire-to-roll press die cutting technology has become increasingly popular. The importance attached.

The characteristics of wire round die cutting

A few years ago, the domestic market for wire-bonded circular die-cutting equipment was still a blank. The wire-bonded round die-cutting roll used in gravure production lines and flexographic printing production lines also relied on imports. With the improvement of domestic manufacturing levels in recent years, the production of wire-bonded circular die-cutting rolls and die-cutting equipment has also become localized, and domestic customers are increasingly interested in ordering round-pressed circular die-cutting rolls in China. Beijing Nanfeng Seiko Die-cutting Machinery Manufacturing Co., Ltd. and Shanghai Bernel Yawha Printing & Packaging Machinery Co., Ltd. are domestic manufacturers specialized in the manufacture and maintenance of round press die-cutting rolls and die-cutting equipment, mainly for gravure production lines at home and abroad. Flexographic printing production lines, etc. provide ancillary round die-cutting die-cutting equipment, which currently has a wide user base in China. The outstanding advantages of wire-bonded circular die-cutting are mainly reflected in the following aspects:

1. high productivity. Printing and die-cutting are carried out on-line, with a speed of up to 200 m/min and high production efficiency.

2. Die cutting quality is good. Circular die cutting is line contact, working pressure is small, product forming stability is good, geometric shape and size are accurate. This is particularly important in beverage packaging, such as Tetra Pak packaging and roof packs. Because the inside is filled with liquid, it requires high indentation, otherwise it may leak when folded.

3. Die-cutting accuracy is high. Compared with off-line die-cutting after printing, wire-cutting circular die-cutting can complete printing and die-cutting on the production line at one time, improving die-cutting precision.

4. long lasting. After round-to-circle die-cutting rollers are used for 12 to 15 million revolutions, they can also be ground 3 times. After each grinding operation, 10 million revolutions can be performed, which is much higher than other die-cutting methods.

5. Save paper. Since the wire-cutting circular die-cutting method uses a web-feeding method, it is not necessary to leave openings and dragging positions during typesetting, and continuous cross typesetting can be performed, which effectively reduces paper waste.

However, there are some disadvantages in the connection of wire round die cutting. First of all, the cost of die-cutting tools is relatively high. A set of imported cutting tools needs more than 1 million yuan, and even domestically produced cutting tools need several hundred thousand yuan. Secondly, the circular press die cutting roller has a long processing cycle. At present, many rounds of circular die cutting rolls used by domestic printing companies are purchased from abroad, and repairs are also sent to foreign countries. The cycle generally takes more than three months. Even if processing is carried out domestically, it will take one month, seriously affecting production. , delay in delivery. Therefore, wire-bonded circular die-cutting is more suitable for the production and processing of large-volume, long-lived jobs. It is not suitable for small-batch, short-run jobs.
