The current situation and development of die cutting and hot stamping equipment in China

after decades of development, China's printing machinery manufacturing industry has reached a considerable scale, and the technical level has also been greatly improved. In the field of die-cutting and hot stamping equipment, especially after entering the 21st century, it has developed more rapidly. Up to now, there are nearly 20 domestic enterprises producing automatic die cutting and hot stamping equipment. In the past, the pattern of Yahua in the South and Yuyin in the North has become history, and replaced by the development status of competition and competition with Shanghai Yahua as the leader

I. current situation of domestic die-cutting and hot stamping equipment

the development of domestic die-cutting and hot stamping equipment has experienced three stages

the first stage was before the mid-1980s. At this stage, China mainly produces vertical flat paperboard die cutting and hot stamping equipment. The vertical flat die-cutting machine, commonly known as tiger mouth, is named for its bite action similar to the mouth when working and its unsafe and easy to hurt people. In any case, it vividly illustrates the working characteristics of the vertical flattening die-cutting machine. Because the production quality and efficiency are related to the proficiency of operators and are prone to safety accidents, the United States and other developed countries have expressly banned the use of this equipment. Due to the limitations of national conditions, the use of this kind of equipment in China is still relatively common, and there are many manufacturers. Due to the low price and large production and sales volume, the annual output of this kind of equipment in China is more than 1000 sets. With the progress of our national humanistic concept and the continuous improvement of labor laws and regulations, this kind of semi-automatic die-cutting opportunity gradually fades out of the application field

the second stage is from the mid-1980s to the end of the 20th century. This stage is the introduction of foreign models, mapping imitation stage. The main products are horizontal automatic flat pressing and hot stamping die-cutting equipment. At that time, only Shanghai Yahua and Hebei Yuyin were able to produce such products in China. However, the overall performance is not high. The maximum mechanical speed is about 5500 sheets/hour. Hot stamping is in the form of foil pulling, and the failure rate is also relatively high

The third stage is after entering the 21st century. This stage is to eliminate these uses, including the components and carriers for the charging system, the battery base for the battery system, and the Componentization of sensors and shells for motors, absorb foreign advanced models and technologies, and embark on the road of independent development. Enterprises producing automatic die cutting and hot stamping equipment have also mushroomed, reaching more than 20. In terms of performance indicators, it has been greatly improved compared with the past. The maximum mechanical speed is generally 7500 sheets/hour, and the die-cutting accuracy is about 0.075mm; Hot stamping has developed into the form of foil feeding, and the speed can also reach more than 6000 sheets/hour, with an accuracy of 0.10-0.30mm. In terms of function, the die-cutting machine has changed from single die cutting to standard configuration with waste cleaning function. Shanghai Yahua company also launched a full waste cleaning automatic die-cutting machine with the function of cleaning finished products in 2006; The bronzing machine also has the functions of vertical and horizontal foil feeding, holographic positioning hot stamping, plain silver seam avoiding hot stamping for different users to choose

second, advantages and differences

the manufacturers of automatic die cutting and hot stamping equipment in the world are mainly concentrated in Europe, Japan, South Korea, China and Taiwan, China. In terms of the performance of the automatic die-cutting machine, the sprintera106 per automatic die-cutting machine of Swiss Bobst company has a maximum paper size of mm, with waste and finished product cleaning units, and the maximum speed can reach 12000 sheets/hour, which can be called the new concept model with the highest level in the world today. The machine integrates many novel designs of Bobst company, such as the application of the new concept of front gauge and side gauge positioning device, the paper biting through the paper delivery tooth row, and the photoelectric positioning of the printing mark sleeve line, which ensures the die cutting accuracy at high speed and has good speed stability. In addition, Bobst's sp-104er, sp-106le and other models can reach a maximum speed of 9000 PCS/h. The dymatrix106csd automatic die-cutting machine of Heidelberg company has a different working mode from other brands of automatic die-cutting machines. Its movable platform is above the machine and performs die-cutting from top to bottom. The machine has the functions of cleaning waste and finished products, and the maximum speed can reach 9000 pieces/hour. There is also the jrk105 automatic die-cutting machine produced by IBERICA (IBERICA) of Spain, which also has the function of cleaning waste and finished products, and the maximum speed can also reach 9000 pieces/hour. The products of the above three companies represent the European level at any time. In Asia, mj1040 automatic die-cutting machine of Iijima company in Japan, trp-106-se automatic die-cutting machine of Sanwa company and yt-1040ncs automatic die-cutting machine of Yongxin KC company in Korea are all suitable for paper in mm, and the maximum speed is about 7500 sheets. It basically represents the Asian level. In China and Taiwan, there are many automatic die-cutting machine manufacturers, including Shanghai Yahua, Hebei Yuyin, Tianjin Youheng, Taiwan caishun, Taiwan Xuheng, etc

in terms of the performance of the automatic bronzing machine, Bobst's latest foilmaster 104 fr automatic bronzing machine has a 50% increase in heating capacity, and has a Bernoulli paper stop system, with a maximum speed of 8000 sheets/hour, which can be called the fastest flat bronzing machine. It is reported that foilmaster 104 has a very accurate foil to sheet registration device (FR configuration or aluminum foil registration), so the hot stamping accuracy is very high. In addition, Bobst's sp-102 BMA foilmaster automatic hot stamping machine and the company's spieria foilmaster 102 automatic hot stamping machine exhibited at ipex06 Birmingham exhibition can reach a maximum speed of 7500 sheets/hour, and holographic positioning hot stamping can also work stably at 6000 sheets/hour, representing the highest level in the world. Gietz company, a Swiss company that produces automatic hot stamping machines in Europe, is also able to resist stress and fatigue. However, due to its small output and scale, the company has less sales in China. The domestic manufacturers of automatic hot stamping machines are represented by Shanghai Yahua, Tianjin Youheng, Hebei Yuyin, etc. in Taiwan, caishun and Xuheng have strong strength

domestic automatic horizontal flattening die-cutting machine and bronzing die-cutting machine still have certain competitive advantages. On the one hand, compared with imported die-cutting and hot stamping equipment, domestic die-cutting and hot stamping equipment has obvious advantages in performance price ratio. The price of domestic machine is only equivalent to 1/5 to 1/4 of the same type of imported machine. In addition, the after-sales service of domestic machines is also more timely than that of imported machines, and the work response time is faster. At present, many domestic die-cutting and hot stamping equipment manufacturers have successively passed ISO9000 quality system certification, European safety CE certification and the continuous development of high-end new products to gradually shorten the gap with international advanced models and realize export. For example, the products of Shanghai Yahua company have won the first place in the export of complete machines in the domestic packaging machinery industry for many consecutive years, and the price of exported products is higher than that of domestic products, which is really exported

however, compared with the world's advanced models, domestic products still have a large gap, mainly in the following aspects:

first, the speed is not fast enough and the accuracy is not high enough. As the leader in this industry, Swiss Bobst company exhibited an automatic full waste removal die-cutting machine with a maximum speed of 12000 pieces/hour as early as drupa 04. The mainstream die-cutting equipment in Europe and Japan has a speed of 9000 pieces/hour, and the die-cutting accuracy is usually 0.06mm; In terms of hot stamping equipment products, Bobst's maximum speed is 8000 sheets/hour, and the hot stamping accuracy is usually 0.05-0.20mm. In contrast, the maximum speed of the domestic automatic flat pressing die-cutting machine is 7500 sheets/hour, and the accuracy is 0.075mm. The maximum speed of the bronzing machine is 6000 sheets/hour, and the accuracy is between 0.10 and 0.30mm, which is still in the middle level

second, the stability is not high. Domestic die-cutting and hot stamping equipment is restricted by the domestic basic machinery industry, such as materials, heat treatment process, machining, inspection means and other conditions, which makes the accuracy of parts discrete, and the quality between batches and even between products in the same batch is different, resulting in poor stability of products leaving the factory. On the other hand, compared with imported high-end die-cutting and hot stamping equipment, the durability of the product still has a big gap, which is mainly reflected in the change of registration accuracy after using for a period of time

third, the versatility of accessories is not high. There is a big gap between domestic die-cutting and hot stamping equipment and developed countries in parts processing and machine assembly at the same time. Therefore, the versatility of accessories such as honeycomb panel, plate frame and bottom template cannot completely reassure users

in addition, although the number of emerging die-cutting and hot stamping equipment manufacturers is large and the development speed is fast, the overall level of specialization is low, the overall technical level is low, and the proportion of powerful enterprises is small. Especially since the beginning of the 21st century, the number of domestic die-cutting and hot stamping equipment manufacturing enterprises has increased sharply. In addition, Taiwan and foreign manufacturers continue to build factories in China, which has brought fierce competition to the domestic die-cutting and hot stamping equipment market

III. Development Trend

1. Development in the direction of automation, intelligence and digitalization

with the continuous increase of human resource costs and the repeated decline of profits in the printing industry, saving operation assistance working time has become a problem that must be considered for die cutting and hot stamping equipment. Therefore, data communication between multiple programmable controllers; LCD intelligent operation display screen, man-machine dialogue; Digital servo; Holographic aluminum foil surface tension control; Hot stamping holographic machinery and precision manufacturing technology will continue to be used. At the same time, as a post press surface finishing process, the production line composed of die-cutting indentation and digital printing equipment can carry out personalized processing and on-demand processing. Die-cutting indentation hot stamping, together with prepress and printing, has become an indispensable part of the digital printing process. Therefore, die-cutting hot stamping will also be included in the scope of digital workflow. Improving the compatibility of die-cutting hot stamping equipment in this regard is also the development direction of domestic products

2. Strengthen the research on the key technology

due to the particularity of the structure of die-cutting and hot stamping equipment, its key technology is quite different from other printing and packaging machinery. The key technology that restricts and affects the accuracy and speed of domestic die cutting and hot stamping products is the direction that needs to be strengthened in the future. For example, for the intermittent motion drive mechanism of tooth row, parallel indexing cam mechanism is widely used in domestic products, while Bobst uses sector gear mechanism. In addition, the key technologies such as conjugate cam driving movable platform mechanism, photoelectric front gauge and side gauge positioning device, working pressure detection function, hot stamping control system and so on deserve in-depth study

3. Multifunctional die-cutting and hot stamping equipment with independent intellectual property rights

in order to make the post press processing technology more perfect and accurate and improve the operation efficiency, the die-cutting indentation is carried out together with the processes or functions such as bronzing, embossing and full waste removal, which is also one of the development directions of die-cutting and hot stamping technology in the future

after years of development, domestic die cutting and hot stamping equipment manufacturers have accumulated a certain degree of design and manufacturing experience. On the basis of digestion, absorption, imitation and innovation, developing high-end products with independent intellectual property rights is not only the requirement of enterprises, but also the requirement of the country. In this regard, Shanghai Yahua company is at the forefront. For example, the mw1050yc automatic die-cutting machine for finished products launched by the company fills the domestic gap and ends the history that such models have always relied on imports. Tym1050 series automatic hot stamping machine developed by Yahua has the functions of vertical and horizontal foil feeding, holographic positioning hot stamping and plain silver hot stamping, and the vertical hot stamping can be expanded to 9 axes at most, and the horizontal hot stamping can cover the whole
