Traditional laser emits a laser straight high temperature, allowing the welding steel melt instantly. However, laser welding straight seam curve of some complex parts, they often need to constantly changing position of parts, in order to accurately welding, efficiency is not high. Plus lens, so that the original laser beam is reflected straight "bend", the computer controls the angle of reflection, where welding means where mobile phone accessories laser engraving machine, parts can be transposed without comprehensive three-dimensional welding. Yesterday, the first set of three-dimensional laser remote welding systems equipment laser engraving machine, the laborers technology with a German laser equipment companies jointly developed. Metal accounts for a large proportion of the plastic shell laser engraving machine marking material, such as anodized aluminum, stainless steel, copper and titanium. Aluminum, brass and copper such as a highly reflective material marking laser engraving machine electronic devices, require high peak power and a sufficiently high power density laser marking speed peak energies can reach 500mm / s . Dark anodized aluminum surface oxide film, this film is a high absorption of infrared radiation, so in fact require a lower power density, marking speed up to 2m / s. To achieve the above-described marking speed, require a high pulse repetition frequency, because if the speed is too fast and the pulse overlap is not enough, can lead to rough and not coherent line identification; higher pulse frequency pulse overlapping degree can be increased, so that a uniform line identification smooth. Fiber laser operating frequency exceeding 100kHz, which is also applied to the marking field advantage. Annealing the type marking on stainless steel material, the resulting identity is clear, black identity and no material is removed during processing. Now this marking process has been widely used on the stainless steel products computer accessories laser engraving machine, laser engraving machine manhole laser, fiber laser engraving machine provided by Dongguan Guan Jun Laser Equipment Co. Dongguan Guan Jun Laser Equipment Co., Ltd. (www.dgaprime.com) strong, credible, in machinery and industrial products, project cooperation and other industries in Dongguan, Guangdong has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead crown Jun laser into the brilliant and you work for a better future!
