The hottest laser digital paper processing technol

Laser digital paper products processing technology

for the traditional die-cutting process, the efficiency and flexibility of laser digital paper products processing technology have strong competitiveness

in foreign countries, laser digital paper products processing technology has been touted to the extreme by advertisements. It makes materials evaporate to complete various post press processing operations, and now it is gradually developing to mainstream applications. So how far can it go in the end

the standard laser digital paper processing system includes a CO2 laser, power supply, cooling device, controller, software, smoke collection system and web processing system (if it is not integrated into the existing printing or post press processing line, it is configured in this way). In addition, in the case of strict requirements for positioning and registration, a camera based vision system is also needed. The investment amount of this technology should be between us $180000 and US $300000, which is equivalent to a major upgrade of the prepress system

the traditional system uses a fixed laser, and a movable X-Y platform is placed under it, which hinders the use of this technology by users due to speed constraints. The new "galvanometer" system (using a scanning galvanometer) helps the laser move quickly through an adjustable beam and rotating mirror. It is said that its standard processing speed range is 80ips to 600ips

the laser system of roller to roller can realize step-by-step movement, so that the system can move intermittently or in the way of reading, and complete cutting in the process of movement. The continuous movement of the laser system is based on the pre arranged blanking procedure. By adjusting the cutting speed, whether the light beam completely penetrates the material is realized, and the cutting of the material is completed. If the laser parameters are set differently, the material can be pressed out of line marks of different depths, or perforated on the material

advantages

laser digital paper processing technology has many advantages. In terms of flexibility, this technology can process any shape that has been programmed; And also do some coherent understanding, and the laser can complete the cutting in any direction. The shape of the template can be changed quickly without the help of any tools, which makes it possible to process competitive personalized packaging or trademarks. Accuracy is also one of the advantages of digital systems. It is said that the conventional tolerance of paper product processing by repeating 5 ⑴ 1 steps with laser is 3 mils, and it can even compensate for the inaccuracy in the process of printing and post press processing. For example, the material may have telescopic deformation, and the laser can adjust according to these deformation, but the traditional template making cannot

the system is also popular in terms of production efficiency and productivity. The design scheme can be modified at the last minute without affecting the whole production process. Simple and complex shapes are completed in the same time at the same cost. From the perspective of return, end users can control the production of short version or medium version without manufacturing a large number of templates. It can respond to customers' needs more quickly, because it does not need to make a mold

laser cutting eliminates the use of all tools, such as rotating molds, punching and cutting tools

from the perspective of aesthetics, it also received a positive answer. The non pressure cutting process of laser usually does not damage the material, and when testing the self-adhesive trademark, it is found that the trademark cut by laser light pressure has a better stripping cycle than the trademark made by rotating mold, and the separability is selected according to the wall thickness of plastic parts

market space

in the packaging field, the laser digital paper processing market is still in its infancy, but it is a completely open market. Lasersharp of lasx company can be applied to various packaging applications

at present, more and more enterprises have expressed great interest in this, many of which are companies with digital printing machines. They regard digital laser template technology as a feasible scheme to improve the competitiveness of digital printing. According to the introduction, the linear speed of laser can match the linear speed of digital printing machine. Theoretically, users can run ten different printing and post press processing operations continuously without stopping halfway

wave front technologies' softdietm digital laser paper products processing system is specifically targeted at the trademark products processing market, and is said to be compatible with almost all existing trademark printing machines; It can also be used for single machine processing. The system also features a variety of laser options and 600 IPS speed

at present, digital laser paper products processing systems have been installed in various fields of the packaging industry, but most of the installation of these systems are quite confidential, and the manufacturers of the systems must sign confidentiality agreements. Although the whole technology has gradually taken shape, the market itself is still in the early stage of development

acuteartm and acubreathetm laser systems and equipment of laser machining company can provide laser indentation and laser micro drilling operations for flexible packaging. The laser can accurately cut the multi-layer package without damaging its internal structure. Without perforation, the package still remains sealed

the laser technology applied to flexible packaging can also complete many special operations that cannot be achieved by die cutting technology. For example, the rotary die cutting technology cannot make super small holes to ensure breathing, and the rotation cannot cut very clean holes, and the resulting holes may also be blocked by residual materials

development

suppliers continue to work hard to remove obstacles for the installation of lasers. The compatibility of materials has always been closely linked with the material manufacturers, especially now that the laser can handle the corners of the shape, and the surface material can be cut off without damaging the substrate material

more and more special controllers, such as laser Ma Jinan Ruima experimental machine, have the functions of real-time display of the real-time force value, displacement value, fracture value, peak value maintenance of the maximum force value, automatic shutdown, and dynamic real-time drawing of the curve between the tensile displacement and the tensile force value (compression displacement and compression force value). ACU power galvanometer controller of China company has the function of automatically adjusting the laser energy, This is very useful when sketching the corners of complex patterns or figures. Suppliers also continue to pursue processing speed to compare with the speed of traditional printing machines. According to wave front technologies, the company's softdie system has been proven to be between 100 FPM and 300 FPM, depending on the complexity of materials and operations

at present, laser technology is a very special application in the application of post press processing. Some experts suggest that laser digital paper processing is a very accurate and high-level technology, which requires a certain cost investment. If you can achieve the required speed and accuracy by using the rotation technology, then continue to use the rotation technology. Each technology has its own space, and each technology can be well operated in the same production line
