Carton packaging printing companies how to buy die-cutting machine

Die-cutting machine is an important equipment for carton printing. The quality of die-cutting not only determines whether the subsequent production of the carton (such as high-speed packaging) can proceed smoothly. Will also directly affect the quality of product packaging and promotional effects on the product. Therefore, carton packaging and printing companies must correctly choose die-cutting equipment, master die-cutting technology, and produce high-quality carton packaging to meet the needs of customers. Strengthen the company's core competitiveness.

The basic classification of die-cutting machine

According to the difference of the embossing structure, the die-cutting machine is mainly divided into three types: flat pressing, round pressing and round pressing. As the packaging printing industry at home and abroad has basically no longer use round flat die-cutting machines, only flat and round presses are introduced here.

1. Flat Press Die Cutting Machine

Flat die-cutting die cutting machine is the most widely used type of hungry. It is also a type of model that is supplied by die-cutting equipment manufacturers at home and abroad. Flat die-cutting die-cutting machine can not only achieve manual feeding, semi-automatic die-cutting, but also can achieve full-automatic high-speed linkage die-cutting; not only can cut corrugated cardboard, cardboard, coated paper, but also die-cut rubber, sponge, metal plate Wait. Flat die-cutting die cutting machine can be divided into two kinds of vertical and horizontal, in which vertical flat die cutting machine commonly known as "Tiger mouth", poor security. Has gradually withdrawn from the market; currently the most widely used in the market is a horizontal flat die cutting machine. In addition to its die-cutting function, it can also achieve the function of stripping and hot stamping. Its advantages are high die-cutting pressure and wide range of materials, from 0.1mm whiteboard to corrugated cardboard not exceeding 5mm in thickness. . Currently there are many manufacturers of horizontal flat die-cutting and die cutting machines. There are Shanghai Yahua Printing Machinery Co., Ltd., Tianjin Changrong Printing Equipment Co., Ltd., Tangshan Yuyin Printing Machinery Co., Ltd., Beiren Group, and Beijing Victory Albert Printing Machinery Co., Ltd., Henan Xinji Co., Ltd., etc.; abroad there are Swiss Bobst, Germany IMG, Japan ASAHl, the United States Standard Carton Machinery Company, Spain IBERICA, Korea YoungShin Machinery Co., Ltd., Japan IIJIMA and so on.

2. Round press die cutting machine

The circular press die-cutting machine introduced here mainly refers to a web-rolling circular die-cutting machine. Due to its high production efficiency, it has developed rapidly in the domestic market in recent years. The upper and lower tools used in the round press die cutting machine are all round rollers, which are in line contact with the paper, and the die-cutting pressure is small; it can be produced continuously with high production efficiency; it can be used with rotary printing machines (such as web offset press, soft Printers, gravure printers, etc.) connection die-cutting. Die cutting can also be done in stand-alone mode. The round press die cutting tools are mainly divided into two types: press cut type and shear type. The assembly method of the knife roll includes two types of knife block type and integral type, both of which are high-precision engraving precision machining and pass special surface. Heat treatment, with a certain degree of hardness and durability.

In the past, circular die cutting tools relied on imports, which had a high cost and hindered the promotion and application of this type of equipment in the domestic market. In recent years. With the rapid development of the domestic machinery processing industry, a number of round-pressing die-cutting equipment manufacturers have rapidly developed, and their round-to-circle die-cutting tools have reached or exceeded the technological level of imported similar products. The pressure-cutting tools are mainly represented by Beijing Nanfeng Seiko Die Cutting Machine Manufacturing Co., Ltd., Beijing Jincai Precision Machinery Technology Development Co., Ltd., and Beijing Yuncheng Jingda Printing Machinery Manufacturing Co., Ltd.. The representative manufacturers of shearing cutting tools are mainly Shanghai. Bernell-Yahua Printing & Packaging Machinery Co., Ltd. In the aspect of circular press die cutting machine, Beijing Jincai Precision Machinery Technology Development Co., Ltd. has been a relatively mature and successful case, and its round-bore circular die-cutting machine is a better alternative to imported products.

Problems to be aware of when buying a die cutting machine

Carton packaging and printing companies should pay attention to the following points when purchasing die-cutting machines.

(1) The die-cutting scheme should be determined according to the market conditions and product structure. Flat and flat die-cutting methods and round-bore circular die-cutting methods have their merits. Flat die-cutting and die-cutting methods are flexible in production, low tool cost, and suitable for short runs of small batches. Production, but the production efficiency is relatively low; circular press die cutting tool cost is high, suitable for large quantities of long-lived production, such as cigarette packets, milk boxes, toothpaste boxes, boxes and so on.

(2) The compatibility of the equipment should be taken into account when purchasing the flattening and die-cutting die-cutting machine, and whether to select the hot-stamping and automatic scrapping device should be determined according to the product requirements. Hot stamping is an important surface finishing process for high-grade packaging prints; automatic stripping devices can reduce the labor intensity of workers. Increase productivity.

(3) When purchasing a round press die cutting machine, it is necessary to rationally analyze whether the connection mode or offline mode is selected. The connection method has high production efficiency and high requirements for equipment manufacturing control technology. Therefore, equipment manufacturers with strong technical strength must be selected: off-line operation is flexible, production is easier to control, but production consumption will increase.

At present, the round press die cutting machine can be equipped with a round press hot stamping function. The hot stamping die cutting is completed at one time and the production efficiency is high. Beijing Jincai Precision Machinery Technology Development Co., Ltd. manufactures more than 820 multi-color group round press round die cutting machine technology is more mature. It also features holographic hot stamping. Tianjin Changrong Printing Equipment Co., Ltd. developed a two-unit sheet-fed flat press die-cutting die-cutting machine to complete two processes on one machine. Improve production efficiency and save production space. It is also an eye-catching technological innovation.

When carton packaging and printing companies purchase die-cutting machines, the processing quality and assembly accuracy of the components of the equipment should be the focus of inspection. The flat-pressure die-cutting die-cutting machine should focus on the quality of the intermittent mechanism, chain, guide rail, and paper-feeding teeth. The round press die cutting machine mainly inspects the control technology of the equipment manufacturer and the die cutting accuracy of the equipment (generally controlled at ±0.15-0.2mm), and at the same time focuses on the matching capacity and the use price of the round press die cutting tool.
Development trend of die-cutting machine

The future development trend of the die cutting machine is mainly reflected in the following three aspects.

(1) The level of automation and intelligence for automatic, intelligent, multi-functional die-cutting machines will surely increase. The automatic loading and unloading device and the automatic cleaning device will become more and more perfect. The functions of the device will also be increasingly diversified. It can be die-cut or hot-stamped, as well as hot stamping holographic marks.

(2) The further development of high-speed, high-efficiency, high-precision machine manufacturing technology and electrical control technology will further promote the speed and accuracy of the die-cutting machine.

(3) The market space of the round press die cutting machine will further expand The round press die cutting machine can be conveniently combined with web offset presses, flexo presses, gravure presses, and other web printing presses to form a print die cutting production line, which can satisfy Mass production requirements. The product quality is stable, and the production efficiency is unachievable by flat die-cutting and die cutting machines. In the future, the application of round press die cutting machines will increase substantially, and its market space will also be further expanded.
