As a modern precision processing method, laser engraving machine has incomparable advantages compared with traditional processing methods such as printing, mechanical scribing, and EDM. Laser radium engraving machine is maintenance-free, flexible and reliable, and is especially suitable for fields requiring high precision, depth, and smoothness. Therefore, it is widely used in the hardware industry. Metal products that can be processed include iron, copper, stainless steel, gold, alloys, aluminum, silver, and All metal oxides. The laser engraving machine can mark various characters, serial numbers, product numbers, barcodes, QR codes, production dates, etc. On hardware products, the time, date, serial number, and product number can be automatically skipped. The text and graphics marked by laser are not only clear and fine, but also cannot be erased or modified, which is very conducive to product quality and channel tracking, and can effectively prevent the sale of expired products, anti-counterfeiting and cross-delivery. Answer from laser engraving machine manufacturers: The hardware products engraved by laser engraving machines have fine patterns, the smallest line width can reach 0.04mm, are durable, and the marks are beautiful and clear. The laser engraving machine can meet the needs of printing a large amount of data on extremely small hardware products, and can print two-dimensional barcodes with higher clarity and precision. Compared with embossing or jet marking, laser radium engraving machine has a broader market at home and abroad due to its powerful functional advantages. As a new type of marking equipment, laser engraving machines are gradually showing more and more excellent performance and quality, and the use of laser engraving machines is also increasing year by year, especially in the hardware industry.
