Hot stamping equipment from hot stamping technology (2)

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.
From the hot stamping technology to see the choice of hot stamping equipment In the fierce market competition, in order to highlight the exquisite product packaging, increase the added value of the product and more effective security package, more and more product packaging using hot stamping equipment to With high speed, high accuracy and easy operation, wide application and other characteristics.
The market's demand for hot stamping equipment has driven the constant updating and creation of stamping equipment manufacturers. In the face of numerous equipment manufacturers and colorful hot stamping equipment, it is especially important for printing companies to carefully select and support hot stamping equipment.
At present, the hot stamping process can be divided into ordinary hot stamping, hot stamping and embossing once completed, and hologram trademark hot stamping in three main ways.
First, the ordinary hot stamping According to the different aluminum materials, ordinary hot stamping is divided into ordinary aluminum production process is different, so there is a situation in the peeling of the laser in the hot stamping of aluminum foil is more difficult, reflecting the appearance of a hot stamping aluminum foil If it is not true, the peeling is incomplete and hot spots are not present. At this time, contact the supplier of aluminum materials. According to the texture of the stamping substrate (substrate), the supplier shall provide more suitable anodized aluminum materials, and in the normal aluminum In hot stamping, according to the requirements of different atmospheres in different aluminum production plants, the most appropriate temperature, speed, and pressure are selected during hot stamping to achieve the best results of hot stamping.
Commonly used hot stamping processes are round flat stamping and flat stamping, among which the round stamping stamping has many unique features due to its line contact.
1. Hot Stamping Substrate The widely different hot stamping substrates have different requirements for anodized aluminum and hot stamping equipment. Because the aluminum foil has certain adaptability requirements for the hot stamping substrate, before the hot stamping on the surface of different substrates, it is first necessary to inquire about the application of different aluminum grades on different materials, such as on the white card. Hot stamping on paper, ink, UV inks and composite films requires slightly different galvanized aluminum. In addition, choosing the right equipment for different hot stamping substrates is also very important. For example, in the case of hot stamping on coated paper, the time required for the thermal contact between the electrodeposited aluminum and the thin wax is not too long, but it is necessary to ensure the normal transfer of the electrochemical aluminum. Therefore, the same type of electrochemical aluminum used for coating is used. Only the flattened hot stamping method can be used, because the round hot stamping method is the line contact, the entire paper hot press time is longer, but the contact time evenly distributed on each line is very short, so as not to damage the film Layer, and the temperature is even, it can show the bright effect of hot stamping anodized aluminum.
