Hot stamping equipment from hot stamping technology (3)

2. Suitable for large-area hot stamping When hot stamping a large area of ​​electro-aluminum (such as field and pass-through lines), the round-press hot stamping method is also better than the flat-press hot stamping method. Because of the round hard-line contact method, it is easier to remove the aluminum foil and completely eliminate the air, effectively solving the phenomenon of misprints and stencils that often appear in flat stamping and hot stamping.
In order to achieve anti-counterfeiting and increase the added value of goods, most of the products in modern hot stamping are registration hot stamping, and the precision requirements are very high. Hengheng MK series round flattening hot stamping machine is improved on the basis of the original Heidelberg printing machine. With the superior performance of the world's excellent printing presses, the repeated hot stamping accuracy can meet the requirements of the screen four-color printing. Therefore, it provides a strong guarantee for hot stamping, and the accuracy of repeated hot stamping can be within plus or minus 0.02 mm. However, if such equipment is not completely refurbished, it is difficult to achieve such accuracy requirements.
Although the flat pressing hot stamping machine has great difficulty in solving the hot stamping accuracy problem, the hot stamping speed is high and it is suitable for processing large-volume long-lived jobs.
At present, domestic flat stamping stamping equipment is limited by the material and heat treatment process, and the accuracy of secondary repeat printing needs to be improved; while the high precision Bobst stamping machine is also expensive. Therefore, Hengheng Company has introduced a flat stamping press on the basis of the introduction of foreign advanced technology and key materials and components. Its secondary hot stamping accuracy can reach plus or minus 0.085mm, basically meeting the customer's requirements for overprinting, and at the same time overcoming The low-speed problem of round flattening stamping machine, the highest hot stamping speed can reach 5000 sheets/hour.
The above is the advantages and disadvantages of the flat pressing hot stamping and the round pressing hot stamping machine in thick paper hot stamping. Thin paper sets should be printed when printing the advantages and disadvantages. In the thin paper sleeve hot, you should buy round press hot stamping machine, because the flat pressure equipment is limited by the structure is difficult to control the smooth running of the thin paper in the run, in the mass production, the use of flat pressing equipment hot stamping Thin paper can be written as a large scrap rate, which is inconsistent with high speed.
Second, hot stamping, embossing bump once completed In fact, as early as the early 1980s, many manufacturers in China have completed a hot stamping, embossing attempts, but the process only stays in the gap is not high precision micro hot words Level. In recent years, more and more manufacturers have asked to complete the set of hot stamping on the product, and it is required to stamp out the obvious bumpy images. The key to this process is plate making. After the ordinary hot stamping plate is corroded, the graphic part is a right-angled line, while the hot stamping, embossing and stamping hot forming plate requires the graphic part to be a fillet line, so it is used for hot stamping and embossing once. The hot stamping plate of the molding must be treated after the corrosion, and the artists who are proficient in the process in the country are reduced year by year, making this process limited. As a last resort, many manufacturers have to go abroad to make plates. The international well-known plate-making company - Kurz Company adopts advanced electric carving method to produce hot stamping, embossing and stamping one-step hot stamping printing plate with high precision. Although the price is expensive, the hot stamping effect is very exquisite.
This process in the selection of equipment, we must choose a high precision stamping machine, because this process requires the two convex and concave template, once the machine is not enough precision, it will cause the male mold damage. Although the accuracy of circular flattening and hot stamping equipment is high, but it is difficult to operate, special attention must be paid to the thickness of the drum lining and the height of the lower platen to ensure that the line speed of the equipment during operation is consistent. Otherwise, the plate speed may be caused by inconsistent line speeds. Because of the accuracy problem of most flattening and hot stamping machines, after the second edition, the edition will change, and it is very easy to cause damage to the punch. The new company's MK Series A round flat pressing hot stamping machine adopts a patented lifting platform device, effectively solving the above problems, and is currently being promoted. If there is a Hengping flattening hot stamping machine, the operation will be more convenient than a round flattening hot stamping machine. However, no matter what equipment is used in this process, it must be carefully adjusted.
Third, holographic hot stamping laser full hot stamping technology is a new type of laser anti-counterfeiting technology, from the advent of only a few years now, but has been widely used abroad, mainly for a variety of tickets, credit cards, passports, Anti-counterfeiting of banknotes, trademarks, and packaging. According to the characteristics of hologram hot stamping, holographic hot stamping is divided into continuous pattern hot stamping and independent trademark hot stamping.
Since the hologram marks are arranged in a regular and continuous manner on the electrodeposited aluminum, several words or patterns are stamped as a whole to the final product at the time of hot stamping, and there is no high requirement for the accuracy of the hot stamping. Such hot stamping is applied to the equipment. The requirements are not as high as the general hot printing equipment can be completed, in the choice of equipment and the general hot aluminum hot slip too much difference, not only the production of such aluminum is not easy to grasp the production process, and high investment in equipment. Frontier hologram logo hot stamping is a new generation of ordinary laser holographic hot stamping products (Note: General laser holographic technology is currently used in adhesive labels).
3, the independent design of holographic logo hot stamping high-end products In order to make the holographic logo stamping can produce a good security effect, I use most of the independent logo holographic logo stamping, that is, the holographic logo on the anodized aluminum into a separate trademark logo , And in each pattern have alignment mark, which puts high requirements on the function and accuracy of the stamping equipment, not only requires the equipment with a positioning identification system, but also requires that positioning stamping accuracy can reach within plus or minus 0.5mm Otherwise, the standard high-standard designs deliberately designed by the manufacturer will result in incomplete stamping or heroism, so as to achieve the effect of preventing counterfeiting and increasing the added value of the packaging. Due to the features of intuitiveness and high technical difficulty, the hot stamping of the independent pattern holographic logo has so far been the best means of anti-counterfeiting for packaging.
Evergrande's two types of hot stamping machines have been the first to introduce this technology in China, and after several improvements, the current hot stamping accuracy can reach within plus or minus 0.22mm, which is a mature product in domestic equipment. Select Hengheng's hot stamping machine, in the selection of equipment only consider the size of the hot stamping area. If the holographic logo is stamped on a cigarette box or other small box, the flat stamping and hot stamping equipment should be used. The national hot stamping stamping hot stamping speed can reach 4,000 to 5,000 sheets/hour, and can meet the small box printing area requirement. If it is on the stencil of a large hologram stamping area, and the required surface pressure, the temperature can not be too high, you should use round flat stamping stamping equipment, such as "Furong Wang" cigarette sliver box.
To sum up, with the continuous development of hot stamping technology, the demand for hot stamping equipment is also increasing, but regardless of the round flat stamping stamping or the flat stamping stamping stamping, each has its own advantages and disadvantages. Both today and in the future, there will be advantages in its use, like offset printing, flexo printing, gravure printing, silk screen printing, etc. No one way can replace the other, but they are all in the process. With the development of hot stamping technology and continuous improvement to meet the special needs of different products.
As a sole manufacturer of two kinds of hot stamping machines in the country, Hengheng Company has the same requirements as the internationally renowned hot stamping machine manufacturers BOBST and STORRA to host materials, electric control systems, and professional electric aluminum pulls. The requirements of the foil control system are very strict, and they are moving towards the start of production and personalized production. While taking into account the quality and safety of its products, it also considers the convenience of operation and the versatility of internationalization. When it comes to helping customers select models, it also reflects its professionalism and excellent professional ethics. (Finish)
