Fiber laser marking industry applications

. Laser marking is a new marking process.

In recent years, with the practicality and sustainability of the laser increases, coupled with improvements in computer technology and the rapid development of optical devices, and promote the development of laser marking technology.

Laser marking is the new processing technology, which developed together with laser welding, laser heat treatment, laser cutting, laser drilling and other applications, through the use of high energy density of the laser beam on the target role, so that the target surface physical or chemical change, thereby Information obtained as a visible pattern, i.e., a high-energy laser beam is focused on the surface of the material, the material is rapidly vaporized to form a pit, as the laser beam moves in a regular surface of the material while controlling the breaking of the laser, the laser beam will in the surface processed into a specified pattern; laser marking or a non-contact, no pollution, no wear new marking process.

About Laser marking principle can be explained, namely computer-controlled high energy density of the focused laser beam to effect a predetermined trajectory mechanical parts, electronic components, instruments and other needs of the workpiece surface markers, so that the surface material to achieve instant vaporization or chemical change change color, etched with a certain depth or color of text, graphics, etc., so as to leave a permanent mark on the workpiece surface.

二.Non-contact laser marking permanent identification

Laser marking is through the use of high energy density of the laser beam on the target role, so that the target surface physical or chemical changes, resulting in visible way mark pattern produced by laser action on the surface of the workpiece firmly permanent marker is its outstanding feature.

Laser marking machine, also known as (laser typewriter, laser printer, laser marking machine), laser processing is an important principle, namely the use of laser-beam irradiation treatment of the material surface, the light energy is converted into heat instantly, so that the surface even molten material instantly vaporized to form a tag.
In recent years, laser marking technology more and more applications in the field of printing, laser marking can be used include plastic and rubber, metal, silicon wafers and other materials, laser marking machine is easy to operate, as long as understand basic computer knowledge , you can operate the laser marking machine; marking in the printing industry, laser marking has the following characteristics:
1. permanent; indicia not the environment (touch, acidic and basic gases, heat, cold, etc.) and subside.

2. The anti-counterfeiting; laser marking technology marks carved out and change is not easy to imitate, to some extent, has a strong anti-counterfeiting.

 3. The non-contact; laser marking is a non-mechanical "knife" for processing, may be any regular or irregular surface of the printing marks and the workpiece does not produce stress after marking, to ensure accuracy of the original workpiece. The work surface does not produce corrosion, no "tool" wear and tear, no poison, no pollution, is a clean, non-polluting high environmental processing technology.

4. Wide applicability; a laser processing means to do, can be a variety of metals, non-metallic materials (aluminum, copper, iron, wood, etc.) processing.

5. The high precision carving; laser marking machine engraving Patterns fine items, the minimum line width of up to 0.04mm. Marking a clear, durable, and beautiful. Laser marking can meet print large amounts of data on a tiny plastic parts need to have a stronger market competitiveness.

6. Low operating costs; marking speed and marked molding, low energy consumption, and therefore lower operating costs. Although laser marking machine equipment investment is larger than conventional marking equipment, but operating costs, the use of laser marking confidential much lower. Illustration: ① plastic transistor marking: marking machine working speed of 10 / sec to 5 years if the equipment depreciation calculation, marking fee 0.00048 yuan / month. If you use a printing machine, its overall operating cost of about 0.002 yuan / month, or even higher.

7. The processing efficiency; laser beam under computer control high-speed mobile (speeds of up to 5-7 m / s), can play a variety of characters, symbols and patterns, marking process can be completed within seconds, easy-to-use label design software engraved pattern, change tag content to adapt to modern production of high efficiency, fast-paced requirements.

8. The development of fast; due to a combination of laser technology and computer technology, the user as long as the computer programming to achieve laser printer output, and can change at any time print design, replacing the traditional mold making process fundamentally, in order to shorten product upgrades replacement cycle and flexible production provides a convenient tool.

If equipped with Q-switched laser or MOPA 10W, 20W pulsed fiber laser laser marking machine, the whole system of marking high precision, fast, stable performance, it can be configured to be able to work long hours of work delivery platform (also available in the customer's production line installed directly) and equipped with encoders and sensors, so that a continuous dynamic line marking more quickly and accurately, with traditional laser marking machine has a higher contrast photoelectric conversion efficiency, higher reliability, easier to operate advantages, and contrast with the traditional inkjet printer ink is more environmentally clean pollution-free advantages of low consumption, more lasting mark with security features. With the continuous expansion of modern laser marking applications, the device miniaturization, efficiency and integration requirements of the laser manufacturing also higher.

三.The applications of laser marking

Laser marking technology is one of the largest laser machining applications. Due to a significant advantage of laser marking, laser marking can play a variety of characters, symbols and patterns, etc., character size can middleweight from millimeters to microns, which have special significance for the security products it has been widely applied in all walks industry, such as used in electronics, instrumentation, communications equipment, packaging, beverages, batteries, sanitary ware, electronic components, integrated circuits (IC), electrical appliances, mobile communications, hardware, tools, accessories, precision instruments, eyeglasses and clocks, jewelry jewelry, auto parts, machinery manufacturing, plastic buttons, plastic marking, cutting, pipeline garments, fabrics, tire surface marking, but also for ceramics colored stickers marking, marking the glass surface for high quality, efficient, non-polluting and low cost modern processing opens up broad prospects.
