from the drupa 2000 exhibition to see the development of die-cutting machine

the drupa 2000 exhibition, which attracts the attention of the global printing industry, has long come to an end, but it has left us a far-reaching impression and thinking. It is not difficult to see the development trend of printing technology and equipment from the latest technologies, processes and equipment of the world's printing industry that need to be exhibited at the exhibition and large-scale experiments (random sampling of production lines). It can be said that it indicates that the era of prepress, printing, post press integration and digitalization is coming

more than 260 manufacturers, including international famous post press processing manufacturers such as Heidelberg, Miller Martini, Kolbus, Wallenberg, Bora, Schneider, boster, etc., exhibited many new high-quality models, which became a highlight 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 for the internal quality of goods and the quality of packaging to find sustainable materials to replace the ABS plastic currently used in Lego building blocks. As an important aspect of post press processing, printing surface finishing technology, such as lamination, glazing, die-cutting indentation, concave convex embossing, bronzing, etc., often plays an extremely critical role in the final quality and effect of packaging and fine printing products, which can not only greatly improve the artistic effect of printing products, but also endow printing products with new functions, and naturally become one of the important means of printing value-added and promotion. Therefore, It is more and more popular

sheet fed die-cutting machine

at present, sheet fed printing processing is the most common production mode of packaging cartons, and die-cutting processing plays a vital role in the processing process. With the vigorous development of packaging and printing industry, there is an increasing demand for special high-end die cutting and bronzing equipment

there are three types of sheet fed die-cutting machines: round flattening, flat flattening and round flattening. At present, the flat flattening machine is the most widely used. Flat press die-cutting machine is divided into vertical flat press and horizontal flat press models, and horizontal flat press die-cutting machine is the most important model of die-cutting machine at present. In order to enhance the function of the machine, the model that integrates the two key processes of die cutting and bronzing is very popular, which is the dual-purpose machine of die cutting and bronzing. This drupa exhibition shows both automatic die cutting machine and automatic die cutting bronzing machine, both of which have the most advanced holographic bronzing function today

die cutting equipment online with printing machine

at present, packaging printing accounts for an increasing share in printing. In bread packaging printing, flexo printing and gravure printing are more and more widely used. In flexo printing and 1kg/day graphene oxide gravure printing, reel materials are widely used. Then, die-cutting equipment used together with reel material printing machines (such as flexo printing machine, gravure printing machine, offset printing machine) will become a new hot spot in the development of domestic die-cutting equipment, and internationally, online die-cutting has become a relatively mature technology

depending on the production scale, the supporting die-cutting equipment can be flat pressed or round pressed

at this exhibition, not only boster company exhibited the die-cutting equipment connected with the printing machine. Other companies also exhibited web printing machines with die-cutting equipment

bhs exhibited a folding carton flexographic press with platform or die-cutting device (BHS flex line
