Deep laser engraving is a common application of laser processing in laser processing. Compared with traditional methods, depth laser engraving has flexible, high-precision, pollution-free engraving content, and can handle complex engraving processes. More and more attention has been paid, and the traditional carving technology is gradually disappearing. The market prospect of laser deep carving is very promising.
Influence of pulse width on laser engraving depth
At present, laser engraving is mainly used for mold engraving, wheel engraving, car VIN code, embossing, steel marks, tank marks, jewelry and other products. Engraving materials include carbon steel, stainless steel, aluminum, copper, high-strength steel, etc. What factors affect the cutting depth of these materials and the roughness of the door? Laser power, beam quality, pulse width, optical output frequency, filling density and processing speed. This paper mainly studies the influence of pulse width on deep thread.
Taking stainless steel as an example, the influence of pulse width on the engraving depth is tested. If other parameters remain unchanged, the pulse width increases and the depth of deep engraving also increases. When the pulse width reaches 350 ns, the engraving depth is maximum. This is because the pulse width increases. If the material damage threshold of the damage peak is guaranteed, the pulse duration is long and the removal efficiency is high, but the shading quality cannot be guaranteed.
Based on the above data analysis, it is concluded that different pulse widths have different effects on the deep carving effect. In practical application, it is necessary to select appropriate parameters according to the needs of deep carving, and consider the efficiency and effect of deep carving. Engraving. Engraving. When the pulse width increases, the engraving depth increases, and the shadow effect remains unchanged. In addition, different material properties have different effects on the depth engraving effect. The melting point of aluminum is the lowest, so the deep etching efficiency is the highest under the same conditions. The fastest.
As a product against counterfeiting in the beverage label industry, the inkjet laser printer, together with the counterfeit traceability system, has realized product customization, made every bottle of wine have traceable identification and query, and increased the number of counterfeit technicians. At the same time, presenting the unique identity of the product on the package is the key to attract consumers. As we all know, in order to pursue short-term economic benefits, some beverage manufacturers unscrupulously use low-quality liquor or unfair competition to distort the market, resulting in the sale of a large number of low-cost liquor. Quality has entered the market. Only through effective means of good consumer management can enterprises stabilize brand sustainability and establish consumer loyalty.
Laser printed labels are widely used in the wine industry because of their unique dyeing and anti-counterfeiting characteristics. Many wineries, such as Wuliangye, Luzhou Laojiao (a kind of Daqu liquor), Jiannanchun, Hemu, etc., use laser printers to print products and connect them with tracking software. When filling, they print provincial certificates for each bottle of white wine and insert barcode on the packaging box to track the product sales process, which plays a role in monitoring counterfeit logistics and cracking down on sales.
The working principle of the inkjet laser printer is to aim the laser at the surface of important objects with high energy density, vaporize the surface materials in a very short time, and accurately control the actual movement of the beam laser. Watermark or text template. The laser marking is clear and cannot be removed or changed. At the same time, the permanent characteristics of laser marking also have a certain anti-counterfeiting effect. Many companies have begun to use laser marking to combat counterfeiting, and have achieved good results.
In addition to fighting against counterfeits and improving the environment, many liquor enterprises are also fighting for relocation of regional businesses. As the ink of the ink-jet printer is easy to be erased, some businesses often change the exclusive area or region number printed on the outer packaging of alcohol products, which not only harms the interests of businesses, but also the interests of alcohol producers. Since the laser marking code cannot be erased, it is the best choice for marking prefix.
