Die cutter machine classification
- According to the different embossing forms, the die cutter machine is mainly divided into three types: rotary die cutting, rotary flat die cutting and Flatbed die cutting.
- According to the form of die cutting plate placement, it can be divided into vertical type and horizontal type.
- According to the degree of automation, it can be divided into manual (semi-automatic) and automatic.
- In terms of function, in addition to die-cutting, there is also a stamping function, which is called a hot stamping die cutter machine, and some have an automatic waste removal function, called a waste-removal die cutter machine.
The rotary die cutter machine is characterized by linear contact, low die-cutting pressure, and high production efficiency. It can be connected with offset printing machines, flexo printing machines, gravure printing machines and other printing equipment for in-line die-cutting, so it has a wide range of applications. One cylinder is equivalent to the impression cylinder, which applies pressure during die cutting; the other is the roller die.
There are two types of roller dies: wood and metal. The former mainly die-cuts very thick corrugated cardboard, while the latter has metal roller dies processed by chemical corrosion or electronic engraving, which are mainly used for die-cutting self-adhesive labels and trademarks. , There is also a metal roller die mainly used for medium and high-end long-term products, which adopts the form of pressure cutting or shearing.
Rotary flat die cutter machines are currently rarely used in the market, so I won’t go into details here. Flat die-cutting machine is the most widely used and most common type at present, and it is also the model with the most manufacturers at home and abroad. Domestic manufacturers include Shanghai Yahua, Tangshan Yuyin, Beiren Group, Henan Xinji Group, Beijing Shengli Weiye, Jeytop Carton Machinery and other manufacturers; foreign countries include BOBST (Switzerland), IMG (Germany), ASAHI (Japan), the United States Standard Carton Machinery Co., Ltd., Spain IBERICA, Korea YoungShin Machinery Co., Ltd., Japan IIJIMA and Heidelberg and other manufacturers.
The flat die-cutting machine can be used for various types of die-cutting. It can not only manually feed semi-automatic die-cutting, but also fully automatic high-speed linkage die-cutting; it can not only die-cut corrugated cardboard, cardboard, self-adhesive, but also Die-cut rubber, sponge, sheet metal, etc.
The vertical flat die cutting machine is mainly divided into two parts: the fuselage and the press frame. The die-cut plate is mounted on the fuselage. According to its action mode, there are two types: single pendulum and double pendulum. The single pendulum type means that when die-cutting, the press frame swings, the body does not move (that is, the plate table does not move), the plate table and the lower part of the press frame contact first, and then the upper part contacts. In this way, the stress time is different, and the stress is uneven, so it is used less and less, and it is gradually eliminated.
The double pendulum type means that during die-cutting, both the fuselage and the press frame move. Before the contact, the press frame lithography plate and the plate table are parallel, and the contact form between them is parallel movement, so the pressure is large and uniform. Most of the vertical flat die-cutting machines currently produced belong to this type. Vertical flat die cutting machine can be divided into semi-automatic and fully automatic according to the degree of automation.
At present, the vertical flat die-cutting machines produced in China are mainly semi-automatic, the die-cutting is done by the machine, and the paper feeding and delivery are done manually. Due to the low price of this equipment, the production and sales volume is relatively large. In addition, a fully automatic vertical flat die-cutting machine has been developed at home and abroad, from paper feeding, die-cutting or hot stamping, to paper delivery, all automatically completed. The typical domestic equipment is the TYM750 hot stamping die-cutting machine developed by Beiren Group Company in 2003. This machine is currently the most advanced post-press equipment at home and abroad. It has two functions of die-cutting and hot stamping. The whole process of die-cutting and hot stamping is automatically completed from paper feeding, die-cutting or hot stamping to paper delivery. It is easy to operate and convenient. With a high degree of automation, it is widely used in hot stamping, embossing and die cutting of paper and cardboard, and can also be used in die cutting and hot stamping of some other printing materials. Due to its advanced technology and high degree of automation, the product price is relatively high. At present, it is difficult to promote this product in China, and it is mainly sold to European and American countries.
Horizontal flat-bed die-cutting machine has two paper feeding methods: flat sheet and roll paper. In addition to die-cutting, it can also have stripping and bronzing functions. The horizontal flat-bed die-cutting machine with roll paper feeding is mainly used for die-cutting printed matter such as self-adhesive labels and trademarks. Sheet-fed horizontal flat-bed die-cutting machine is the most widely used model with the fastest technological development. There are many manufacturers, well-known foreign manufacturers such as Swiss Bost, Heidelberg, etc., domestic companies such as Beiren Group, Shanghai Yahua, Taiwan Youheng, Tangshan Yuyin, Shengli Weiye, etc. The market competition is fierce. The main feature is that the die-cutting pressure is large and the die-cutting range is wide, from 0.1mm whiteboard to ≤5mm corrugated paper can be die-cutted.
