Since the first high-tech round-hot round hot stamping machine was launched at drupa printing expo in 1995, its obvious technological advantage is gradually being recognized by people in the industry and will become a new investment hot spot in the packaging printing industry in the near future. Its obvious technical advantages are shown in the following aspects:
1. Significant increase in production efficiency
just now. The maximum speed of the sheet-fed circular hot stamping machine has reached 12,000 sheets/hour, the holographic hot stamping speed has reached 8,500 sheets/hour; the web-fed stamping machine has a speed of 150 meters/minute and the holographic hot stamping has been 120 meters/minute. The traditional flat pressing hot stamping machine has a maximum speed of only about 6000 sheets/hour. From this we can see that the improvement of its efficiency is very obvious.
2. Large area hot stamping and small text stamping quality are excellent
Taking a 1020 mm × 720 mm folio paper as an example, a flat stamping hot stamping method is used. If the stamping area exceeds 50% of the total area, it is almost impossible to complete a hot stamping. There are two reasons for this: First, it is very difficult to patch the plate, and the more the number of bronzing plates, the more difficult it is to pad the plates. Second, the pressure of the imprinting area is not given. If it is forcibly reached, it will easily cause overload. As a result, the life of the machine is shortened and the precision is reduced. Therefore, in the flat stamping hot stamping, the reduced imposition method is often used to achieve the required pressure. If the proportion of hot stamping area in the entire layout exceeds a certain range, many manufacturers use multiple hot stamping methods. In any case, the bursting of bubbles generated in the hot stamping area on a large area of ​​hot stamping cannot be eliminated. Therefore, many packaging printers would prefer to use an inefficient round flattening hot stamping machine in order to achieve better quality results if they encounter such large area hot stamping products. For small texts and subtle textures, the pressure in the partial area of ​​the flattened hot stamping is lacking, and it cannot be compared with the round press and the round press.
Round press stamping is line contact, and its pressure can reach the pressure level of round press stamping, but the speed is too slow to be only 3,000 sheets/hour. Therefore, it will be subject to certain restrictions when used in mass production.
Round press hot stamping is line contact. Therefore, although the axial pressure between the bronzing roller and the impression roller is not very large, the pressure applied to the unit area of ​​the hot stamping area is quite large. The biggest advantage of round press hot stamping is that it not only solves the pressure problem of large area hot stamping but also eliminates the problem of bagging, while at the same time it guarantees the quality of hot stamping with small text and subtle texture. The advantage of these aspects is that the above two bronzing methods are elusive.
3. Low vibration, low noise
Since the round press has no reciprocating motion, its vibration during operation is much smaller than the Other two methods. Not only does the rotation method provide the possibility of increasing the bronzing speed, but after the bronzing speed is almost doubled, the noise is very low.
4. Holographic hot stamping positioning accuracy
Due to the special structure of the round hot stamping machine, it is possible to make individual identification and separate positioning of each holographic label in the holographic hot stamping, instead of the same as flat stamping and hot stamping. Read one of the markers to complete the positioning of the entire string of holograms. This difference in reading and positioning determines the difference in hot stamping accuracy between the two. The advantage of the round press hot stamping machine in terms of holographic hot stamping accuracy is very obvious. The holographic stamp on the Euro has generally adopted the round press hot stamping method.
5. Save electricity foil
There are two meanings of saving the aluminum foil: one refers to the arrangement of the hologram, and the other refers to how much of the electro-aluminum foil can be actually used in the ordinary bronzing.
In the advanced round hot stamping, it is not necessary to consider the relationship between the distance between the hologram and the bronzing version, and the distance between the two holograms can be reduced as much as possible so as to achieve the purpose of saving the electric aluminum foil. The high-precision reading system can even automatically delete the wiring in the holographic foil roll.
In ordinary hot stamping, the computer can automatically calculate the optimal skipping method that matches the speed of the machine, and even the remaining scrapping edge of one hot stamping area and the next hot stamping area is only 2 mm. The savings in electro-aluminum foil for round press hot stamping are obvious. According to statistics, some European manufacturers can save up to 30% of electro-aluminum foil.
6. Modular design creates greater imagination for customers
The hot stamping unit and embossing unit of the round pressing hot stamping machine can be arbitrarily combined, can adapt to different product structures, and even can install the quality control system on the hot stamping machine, that is, two delivery units can be set, one of which can receive genuine products. , A reject received by the quality control system. In this way, the printed sheets in the genuine delivery pile are all genuine, and can be sent directly to the next process without manual inspection.
7. New member of round press hot stamping machine - web hot stamping machine
Since the main core part of the company is the same patented design for the aluminum foil supply roll and hot stamping parts, the precision and hot stamping quality of the web stamping machine can be consistent with that of the sheet-fed circular hot stamping machine. .
Web-foil stamping machines can accomplish tasks that sheet-fed stamping machines cannot do, such as tipping paper hot stamping.
This new type of web gilding machine can be configured as follows: roll-to-roll, roll-to-sheet, roll-to-die and so on.
8. Ordinary hot stamping and holographic hot stamping are completed once
Because the hot stamping temperature of the round hot stamping machine is obviously higher than that of the flat stamping hot stamping machine (200-250°C), and under the action of high pressure, many electro-aluminum foil manufacturers have successively introduced high-speed circular presses. The bronzing machine's galvanized aluminum foil, so that ordinary bronzing and holographic bronzing is not a problem.
Because of the obvious advantages of round-round bronzing technology in the above-mentioned aspects, it can be foreseen that the round-press bronzing method will soon obtain its corresponding market and bring greater economic benefits to customers.
