Laser-material interaction exists when a threshold power, only the laser power reaches the threshold, the physical process can begin. Laser marking threshold magnitude kW power in general. For high-reflectance surface or a material difficult to be processed, the pulse peak power required to reach a level above 10kW. But for most materials marking applications the phone keypad laser engraving machine, pulse peak power of several kilowatts to meet their needs. Another key parameter is the pulse energy, typically mJ magnitude. The length of the pulse time is a very important feature, because it determines the thermal effect material with time, have a significant effect on the quality of identity. Typically the length of time required between pulses 10 ~ 200ns. Pulse frequency is the number of pulses per second (in Hz), the typical laser marking systems operating frequency range of 20 ~ 80kHz. Average power decided keyboard keys laser engraving machine by the pulse energy and pulse frequency, average power value represents the total energy of the laser can provide. Today, the engraving on the product trademarks, logos and other manufacturers become consensus. Products marked not only allows consumers to understand the product information, making their products with other products to distinguish, can also prevent counterfeiting, improve product quality and so on. Now no doubt the car keys in the product labeling laser engraving machine, laser marking technology is now the most common of the most popular markers. The traditional silk screen printing technology products will fade when the mark, shedding laser engraving machine, ink and other use is not environmentally friendly. The laser marking technology precisely to avoid this laser marking technology can be saved permanently without any substance added only environmentally friendly green product surface carving. And now laser marking machine sales price decreased year by year, which makes a lot of manufacturers in selecting what way mark their products selected laser marking technology. Laser marking technology development in recent years, in many industries and fields have been using. Makes laser marking technology in a dominant position in the market marks.
