Experience in using wire round die cutting technology

If the product has a large volume and a relatively small number of products, it is ideal to use a wire to round press. If a printing company is not printing more than 4 types of products, it is suitable for circular die cutting. Calculated with 4 different types of cigarette packets, the strip box and small box together require 8 sets of tools, a set of tools more than 100 million, 8 sets of nearly 10 million, which is a great investment. The process of some products is more complicated. After printing, screen printing, hot stamping, etc. are also needed. It is not suitable for wire-cutting circular die-cutting, and it is more suitable for offline die-cutting.

The experience of using wire round die-cutting

The wire-bonded round die-cutting method has gradually been accepted and accepted by a large number of printing companies and has been widely adopted. At present, the domestic wireline round die-cutting methods are mainly concentrated in the developed industries such as Guangdong, Fujian, Jiangsu and Zhejiang where the printing industry is relatively developed, and Yunnan, where the tobacco industry is relatively developed. Sichuan, Shandong and other places. There are also many products that use wire-bonded circular die-cutting and die-cutting processes, mainly including cigarette packs, wine boxes, milk packaging, pharmaceutical packaging, trademarks, and labels, among which cigarette packs account for the largest proportion.

The main business of Jinan Quanyong Printing Co., Ltd. is to print cigarette labels for Jinan Cigarette Factory, with large batches and relatively few varieties. In order to increase production efficiency, the method of wire-bonded round die-cutting was chosen. In 1996, they introduced a GR650 gravure production line produced by France’s Shangbang Company. At the end of 1997, they introduced a GR660 gravure production line produced by France’s ATN company. Both gravure lines were equipped with wire round press circles. Die cutting equipment. In the actual production, the production efficiency of wire-bonded round die-cutting die-cutting is very high. FK small-boxes are produced with Shangbang GR650 gravure printing production line. The capacity of the machine is 6 people. The normal production speed is 180 meters per minute (FK small box 100.5mm wide, double row), can produce more than 210,000 small boxes per hour, each shift can produce 1.7 million small boxes.

Sichuan Wuniu Printing Co., Ltd. introduced a BOBST DR55 gravure printing line in 1997. The production line is equipped with a wire round die cutting device. At present, 80% of the company's live parts use wire round presses. Die cutting method. The six or seven varieties of live products that are die-cut by using wire round-bore circular die-cutting are long-lived in large quantities, and the craftsmanship is not too complicated. For some of the more complex work pieces, more TZ sequences are needed, and the printed sheets are still cut. After off-line, hot stamping, screen printing, and other processing are performed in a sheet-fed manner. Finally, flat and die cutting is performed.

At present, many printing companies are equipped with imported circular die cutting tools, but also equipped with domestic die-cutting tools. Home-made die-cutting tools are cheap and cost-effective, and the after-sales service of domestic suppliers is fast and thoughtful, and can help printing companies solve problems in the shortest possible time. However, there are still some gaps between home-made die-cutting tools and imported die-cutting tools, which are mainly reflected in the service life. The impact is twofold: first, the quality of materials (steel) is not as high as in foreign countries; second, the heat treatment process is not as advanced as foreign ones.

At the same time, there are also some printing companies in China that blindly invest in wire-cutting circular die-cutting equipment, and the results are not satisfactory. There are three main reasons: First, some printing companies are actually printing jobs in the multi-variety, small-batch, multi-batch phase, which is not the advantage of wire round die-cutting; Second, the more packaging design The more complicated, the increasingly complex printing process, the inability to complete all the printing and post-printing processes at one time. Third, the relatively frequent package revision may invalidate the expensive circular die-cutting tools, resulting in great waste. .
