Editor's note: Within 10 years, the traditional die-cutting process may disappear in some large packaging and processing companies: In the vast market of packaging products, laser etching processing will be increasingly welcomed and promoted, which will be used by laser technology. Another leap in Die-cutting. Some experts pointed out sharply: "Post-press processing is the weakest link in China's printing industry." After printing, both in terms of technology, equipment, materials, and management, domestic printing companies have a large gap with foreign companies. Die cutting is undoubtedly the key to the breakthrough in the field of packaging and printing.
First, on-line die cutting is the future direction of development The so-called on-line die-cutting mainly refers to on-line flat die-cutting and on-line round die-cutting.
On-line die-cutting has the advantage that sheet-fed die cutting can not match. Some experts predict that it will become the mainstream of die-cutting equipment market in the next few years. On-line die cutting is characterized by high speed and accuracy, which can greatly increase production efficiency, shorten production cycles and reduce production costs.
On-line flattening and die-cutting can reach a maximum speed of 20,000 times per hour, which is much higher than that of sheet-fed die cutting. Because the die-cutting plate used by it is the same as that used for sheet-fed flat die-cutting, the manufacturing process is simple. , Low cost, currently widely used in the post-press processing of medium and long-range packaging products, the market outlook is generally optimistic.
Online circular die cutting is mainly applied to the single-line, high-volume post-press line. Its main feature is a series of operations such as hot stamping, compression molding, die cutting, and decantation of printed reelboards, so that the printed sheets are processed into the final product at one time. According to Xu Wencai, a professor at the Beijing Institute of Graphic Arts, the on-line circular die cutting production speed and die cutting production speed and die-cutting accuracy are generally higher than on-line flat die-cutting, and the current maximum speed is up to 180m/min. The maximum speed of the die-cutting machine can reach 300-350m/min. Online circular die cutting avoids a series of quality problems caused by multi-pass printing, such as surface blemishes, inaccurate positioning of hot stamping, and high scrap rate. At the same time, it reduces equipment investment and floor space, and saves a large number of operators. , shortened the production cycle. Although on-line circular die-cutting has some advantages that are not available in on-line flat die-cutting, due to the high cost of circular die-cutting tools and the complexity of die-cutting, the promotion and application in the country are greatly restricted. . At present, online circular die cutting is only used more and more abroad.
From the perspective of on-line die-cutting development in China, relevant experts predict that it will take at least five years for online die-cutting to be applied in the domestic market.
Second, the quality of the die-cut version is critical The quality of the die-cutting depends largely on the quality of the die-cutting plate. The die-cutting plate only has good quality and convenience of processing, flatness, and robustness to ensure that the die Cutting quality and accuracy.
It is understood that the more popular ones in China are multi-layer large-size plywoods, and fiber plastic versions are used in foreign countries (the German Papro'91 exhibition was first introduced by the Marbach Company) and sandwich plates. Multi-layer wood veneer is susceptible to deformation due to changes in ambient temperature and humidity, which incurs inconvenience for die-cutting production and the storage of die-cuts. At the same time, the dimensional stability of multi-layer wood veneers is poor, and the dimensional error is generally 0.15-0.70. Mm, while the dimensional errors of fiber plastic and sandwich steel plates are 0.13-0.30mm and 0.10-0.20mm, respectively.
The production level and processing level of the die-cutting plate directly restrict the development of the die-cutting market and even the packaging and post-press processing. According to information, prior to 1995, the domestic packaging and printing industry used manual methods to make die-cut versions. However, at present, this process is limited to some small and medium-sized packaging and printing manufacturers as an auxiliary processing method, while there is professional plate-making. The company has been eliminated by the end of the country. In addition, there is a considerable portion of die-cuts that are processed using semi-mechanical methods. According to some experts, there are two main reasons for the use of manual or semi-mechanical die-cutting by these SMEs: First, there are still a large number of packaging products in the domestic market that do not require high quality; second, there is less investment in such equipment. . Experts also pointed out that these processing methods not only wear the cutting tools to a certain degree, but also produce a large amount of dust that also causes environmental pollution.
In foreign countries, packaging and printing companies have generally used laser cutting systems for die-cutting. The cutting system controls the die-cutting plate processing with automatic program, which has the advantages of high speed, high precision and good weight. Now many domestic companies are aware of this, some powerful companies have begun to use laser cutting systems, according to incomplete statistics, there are dozens of domestic laser die-cutting plate-making factory.
However, some people believe that laser cutting will also cause certain pollution to the environment, while the other cutting method - the emergence of high-pressure water jet cutting system not only avoids environmental problems, but also maintains high accuracy and stability.
A considerable number of domestic companies have a misunderstanding. They do not pay much attention to the supporting parts in the die-cutting process of the bottom mold (female mold or backing) and sponge pad, such as different cutting indentations for different structures of paper boxes and carton boxes. The line part should use different hardness sponge mats, there are 5 kinds of 8 kinds or even 10 kinds in foreign countries, but only 2 kinds of domestic use, some only use 1 kind.
Enterprises should consider the difference in benefits brought about by the quality of equipment. High-quality die-cutting equipment must be equipped with high-quality die-cutting plates, die-cutting tools, bottom molds and other raw and auxiliary materials and processing techniques. Otherwise, it will only fail.
Even if a subtle link is not paid attention will affect the precision of die-cutting, affecting the final quality of the finished product.
Third, the domestic market for die-cutting equipment has broad prospects Statistics show that the annual demand for various kinds of die-cutting equipment in the domestic packaging and printing industry is about 600 units, while the manufacturing capacity of die-cutting equipment in China is only 300-400 units. The market for equipment is promising.
With the development in recent years, domestic die-cutting machines have reached a high level in many technical parameters, and some have even approached the international level. At the same time, a number of well-known manufacturers have emerged, such as Shanghai Yahua and Tangshan Yuyin. Wait. There are statistics, the price of domestic die-cutting machine is equivalent to 1/4-1/3 of the international similar products, due to the absolute advantage of the domestic machine in terms of price, the market share in the domestic market has reached more than 80%.
Despite this, domestic die-cutting machine manufacturers are still facing a very serious situation. At present, the domestic die-cutting machine products are mainly concentrated in the middle and low grades, and most of the high-grade die-cutting machines used by domestic companies are still imported products. The main reasons for this are as follows: Domestically-made die-cutting equipment mostly adopts mechanical positioning, and does not use optoelectronic positioning like Boost or other foreign products. Certain key parts also depend on imports; accuracy in registration, product stability, reliability, etc. Compared with similar foreign products, there are large gaps. Some important products will change some years after they are used.
According to experts, accuracy and speed are important indicators for measuring the performance of die-cutting machines and directly affect the qualification rate of die-cutting machines.
Determine the quality of the finished product. At present, the highest precision of domestic equipment is ±0.15mm, while foreign products have reached ±0.1mm. The top speed of the die-cutting machines of the internationally renowned manufacturers BOBST, GWU, etc. can reach 12,000, while the maximum speed of domestic products is only 8,000. Therefore, many domestic large-scale packaging and printing manufacturers have to purchase high-grade die-cutting equipment or even second-hand equipment at a higher price to ensure product quality.
It seems that it will take some time for domestic equipment to bridge the gap with foreign products.
Fourth, the four-point proposal for purchasing die-cutting machines In the past few years, under the influence of funds and the concept of “reprinting before printing, printing after light printing†for a long time, users of imported high-grade die-cutting machines in China mainly concentrated on some southern printing industries. Developed areas. However, in the past two years, many enterprises in the north have gradually realized the importance of post-press processing and have begun to vigorously introduce high-grade die-cutting equipment.
So what are some things worth paying attention to when purchasing a die-cutting equipment? Experts have the following suggestions:
First, we must consider comprehensively the company’s own scale, economic affordability, and product categories, product accuracy requirements, and production volume, and choose appropriate equipment. Do not be too blind.
Second, we attach importance to the accuracy and smoothness of the processing equipment and understand the advanced and technical parameters of the latest domestic and international equipment in order to determine the grade of equipment purchased. Generally speaking, large companies may consider purchasing high-end equipment due to high product quality and quality requirements; SMEs may try to use medium-grade domestic equipment.
Third, inspect the manufacturer's technical service quality, reputation and spare parts supply, and fully understand their partners.
Fourth, we must also pay attention to the quality and processing methods of raw and auxiliary materials, such as die-cutting plates, and then consider the price under the premise of ensuring quality. Do not influence the quality and effect of the entire product because of these small links.
The control to improve processing quality is not only for technicians, operators, and managers.
