Fiber Optic Marking: An Excellent Technology for Marking Metal Nameplates
Metal nameplates are also known as metal signs. Common metal nameplates mainly mark the manufacturer's LOGO, information parameters, or some commemorative patterns. Due to the outstanding performance of metal nameplates in preservation, wear resistance, appearance and texture, etc., it is widely used. The general material of the metal nameplate is a metal sheet, which is used more such as: stainless steel, aluminum alloy, aluminum oxide, zinc alloy, iron, zinc alloy, etc.
The surface markings of metal nameplates, such as pattern drawing, company LOGO printing, contact information, QR code, etc., used to use silk screen printing and pad printing in traditional printing. The working principle of silk screen printing is very simple. First, the pattern to be printed is engraved on the steel plate, and then printed on the surface of the nameplate through the printing screen. Pad printing is to first make the plate that needs to be printed, carve a gravure on the steel plate, and then print it on the surface of the product with a silicone transfer head. The two printing technologies have their own advantages and disadvantages, but with the development of society and the improvement of people's needs, the shortcomings of traditional printing technology are becoming more and more obvious, such as:
1. Poor wear resistance. The wear resistance mentioned here is not the wear resistance of metal materials. It refers to the fact that the ink on the metal surface is often worn away during use, causing blurring and discoloration.
2. Poor adaptability to harsh environments, such as water pump nameplates, air compressor nameplates, mold nameplates and other equipment, due to production environment problems often exposed to soaking, high temperature, chemical pollution, etc., ordinary printing inks can not withstand the environment at all. Destruction.
3. For aesthetic requirements, the appearance of metal surface printing is relatively low-end, which is not suitable for some products with relatively high appearance requirements, such as commemorative medals, metal business cards, exquisite company publicity nameplates, handicraft description nameplates, etc. meet its appearance requirements.
4. Chemical raw materials such as organic solvents and heavy metal elements need to be used in the screen printing process. These substances have certain toxicity and will cause personal injury to screen printing staff. In addition, during the drying process of screen printing ink, volatile chemical raw materials gradually volatilize into the air. Pollution of air and environment.
Advantages of Fiber Laser Marking
Compared with the traditional metal nameplate surface treatment technology, the emergence of optical fiber laser marking has successfully solved a series of problems. It is characterized by high marking accuracy, fast speed and stable performance. Metal surface marking does not require ink and other media to cover the surface, and directly marks the surface of the metal nameplate by laser. And it only needs to be controlled by a computer, the operation is simple, and it can print various complex patterns, characters, two-dimensional codes, etc. Through these advantages, the fiber laser marking machine immediately occupied a large market share of metal surface treatment once it was launched.
