Looking at the development of die-cutting machine from Drupa 2000 exhibition
The Drupa 2000 exhibition, which has attracted the attention of the global printing industry, has long since come to an end. However, the impression it has left on us is far-reaching. From the latest technology, the latest technology and the latest equipment of the printing industry in the world today, it is not difficult to see the development trend of printing technology and equipment. It can be said that it presupposes the integration of prepress, printing and postpress, and the digital era is approaching.

Over 260 manufacturers, including internationally renowned postpress manufacturers such as Heidelberg, Miller Martini, Kolbus, Warrenberg, Polla, Schneider, and Bobst, exhibited many new models , became one of the highlights of the exhibition.

With the development of economy, the improvement of people’s lives, and the acceleration of the process of world economic integration, people have put forward higher and stricter requirements on the internal quality of goods and the quality of packaging and finishing. As an important aspect of the post-printing process, surface finishing of printed products, such as lamination, coating, die-cutting, embossing, embossing, bronzing, etc., is often extremely critical to the final quality and effectiveness of packaged printing. The key role can not only greatly improve the artistic effect of printed products, but also can give new functions to printed products. Naturally, it has become one of the important means for value-added and promotion of printed products. Therefore, it is increasingly favored by people.

Sheet-fed die-cutting machine
At present, sheetfed printing processing is the most common production method for packaging cartons. During the processing, die cutting processing plays a crucial role. With the vigorous development of the packaging and printing industry, the demand for specialized high-grade die cutting and bronzing equipment is increasing.

The sheet-fed die-cutting machine has three types: round-flattening, flat-flattening and round-pressing. The largest application is flat-pressing. Flat die-cutting die-cutting machines are divided into vertical flat-pressing and horizontal flat-pressing machines, while horizontal flat-press die-cutting machines are currently the most important models of die-cutting machines. In order to enhance the function of the machine, it is very popular to combine the two key processes of die cutting and bronzing. This is the die-cutting and bronzing machine. This Drupa exhibition not only shows the automatic die-cutting machine, but also shows the automatic die-cutting and hot stamping machine, both of which are equipped with the most advanced holographic foil stamping function today.

Die-cutting equipment connected with printing machine
At present, the share of packaging printing in printing is increasing, and in surface packaging printing, flexo printing and gravure printing are increasingly used. In flexo printing and gravure printing, a large number of reel materials are used. Along with this, the die-cutting equipment used with reel material printing machines (such as flexo, gravure and offset printing machines) will become the development of domestic die-cutting equipment. New hot spots, and in the international arena, online die-cutting has become a more mature technology.

According to different production scales, the supporting die-cutting equipment can be flat-pressed or round-pressed.

In this exhibition, BOBST not only exhibited die-cutting equipment connected to the printing press. Other companies also exhibited web presses with die-cutting equipment.
