Beam steering Nd: YAG (Neodymium: Yttrium Aluminum Garnet) laser marking provides a unique combination of speed, endurance, versatility and image in a non-contact labeling. Laser marking can generate significant savings in production costs and processing costs, elimination of secondary processes and consumable disposal costs and reduced inventory, cost control and maintenance of quality time. Laser marking frequently improves the aesthetic image tagging, which makes the experience all the materials value.

Of product, plastics are the most difficult in terms of interaction with the laser material and the quality of the image request. The wide variety of colors and materials chemistry and aesthetic needs of plastics applications require particular attention both in physical chemistry and imaging techniques. The successful implementation of laser marking technology requires a thorough knowledge of laser marking function and capabilities and a dedicated team approach, from fundamental user.Marking laser marking is a thermal process that concentrated high-beam laser to create jobs work contrasting mark on the surface of the material.

If the target material absorbs laser light, the surface temperature increases causes a color change in hardware and / or evaporation of material surface.Beam controlled laser marking, engraving mirrors mounted on high-speed multiplier developed computer controlled laser beam on target surface. Each galvanometer provides one axis of movement of the beam on the marking. A group of multi-element optical flat-field focused laser light before the power density to reach the work surface, while maintaining the travel site focused on a flat surface.

The laser output is generated to remove the bar between the strokes.Marking marker capable of operating at speeds up to mm / sec with a speed between successful branding of 50,000 mm / sec 5000. Since the process is based on the thermal conductivity of plastic marker speed is usually slower than the maximum capacity of the guidance system sufficient for the desired results marker beam controlled almost all black and white images, including the double line of variable widths reach and images smaller 0.

0001 inches. Computer Imaging Technology offers this very complicated maps with line widths, resolution and accuracy less than 0.001 inches. Because the image is made by "drawing" with the laser beam, marking depends on the amount and complexity of the text and images. computer-generated images, any graphic or all of the tagging program immediately be changed before a new part is positioned to marking.Nd: 1.06 mm strengthen YAG wavelength of light in the near infrared. They are unique among the various types of lasers, in the sense that much work like a capacitor "optical".

In the pulse operation, the Nd: YAG laser energy reserves between pulses, leading to peak powers in kilowatt-hours of energy from light. A Nd: YAG laser output of 75 watts of continuous light, pulsed at 1 kHz, emits a train of pulses with a peak power of 110,000 watts. The capacitor "optical effect gives the ability to act necessary for the evaporation zone. For applications summary, the laser must be a" hat "high mode, where supply of electricity is relatively uniform across the diameter of laser beam to eliminate "hot spots" in the marking path.

The steered beam Nd: YAG laser marker often replaces acid and electro-etch systems, stamping and punching systems and other brands permanently mark produced by printing or engraving. It replaces other printing systems with less permanent ink plastic plastic more naked jet.Uncoated be doped with a material that reflects the laser wavelength as the absorption of laser light to avoid to lose control of excessive heat and merging areas. colored plastic doped mica, titanium dioxide or carbon-containing materials.

The heat generated by absorption of laser light causes the carbon to migrate to the surface, producing a contrasting dark stain on the bottom intact plastic.Plastics are semi-transparent to a wavelength
