Laser digital etching processing technology has obvious advantages over traditional die cutting processing, and it is another leap in laser technology for "die cutting processing". Laser Engraver digital etching process refers to the laser cutting of the processed material (gasification of the material irradiated by the laser) according to the digitized information, instead of the traditional die cutting process.
A typical laser digital etch processing system consists of a carbon dioxide laser and a scanning head, a power unit, a cooler, a power controller, software, a smoke chamber, etc., if not combined with a printing machine or a processing line, Operating system: For processing with high registration accuracy requirements, an electronic display control system may also be required. The total estimate is between $180,000 and $300,000.
In the old system, the Laser Engraver is fixed, and the processing work surface of the material is moved in the X and Y directions, so the speed is limited and it is difficult to be popular. The new system uses a scanning current meter to drive the laser beam and the rotating mirror so that the laser beam can be fired in all directions, and the processing speed is greatly improved, reaching a range of 80 to 600 inches per second. For reel-to-reel laser processing systems, it is also possible to perform intermittent repetitive machining, that is, repeated processing by the laser beam in accordance with programmed pattern information (as in a continuous dryer). For the etching depth of the material to be processed, as long as the etching speed or the parameters of the laser are adjusted, the flexibility can be adjusted (or completely penetrated, or slightly clicked, for indentation or film uncovering).
1. Flexibility: Any shape, no need to make molds, as long as a program is programmed, the laser beam can be programmed to "die-cut" shape and depth, and can be changed in operation without "tools". This opens the door to personalization or small batch packaging of packages or trademarks.
2, the accuracy is good: the tolerance does not exceed three thousandths of a millimeter. It can also compensate for the error between printing and post-processing, because the laser can be compensated, and in the traditional die-cutting, the mold is difficult to change after it is fixed.
3, high production efficiency: because there is no need to make molds, only need to compile the program, the task will follow, save time and save time. Adjustments can be made at the last minute before starting the process without affecting production. Regardless of the simple or complex machined shape, the processing cost is the same and the time spent is basically the same. Its processing speed can basically match the speed of digital printing, which can form a continuous production.
4, economic benefits: no need to prepare molds, processing tasks bulk and small does not matter, the business source will be broadened. In the traditional die-cutting process, not only the molds are various (such as flat-press type, wheel-press type, punching, piercing, indentation, etc.), but the supporting tools are also complicated, and now all can be omitted.
5, the aesthetic effect: laser etching is pressure-free, so there is no trace on the material after processing; not only the indentation is not seen on the pressure-sensitive trademark, but also easy to peel off.
From the technical point of view, although it has the above advantages, the current promotion and application is still the initial class. Several manufacturing companies have introduced related equipment, such as: LaserSharp, LighteningBolt, Softdie, AcuTear, AcuBreather, etc., all of which are patent registration grades. However, users are often reluctant to let the outside world know about the introduction of such equipment, and even sign a confidentiality agreement with suppliers to maintain their leading position in technology.
