With the application of laser cutting head, sheet metal processing technology has developed rapidly and brought revolutionary ideas to sheet metal processing. Laser cutting head technology and laser cutting head equipment have been familiar and accepted by most sheet metal processing enterprises, and gradually replace traditional sheet metal cutting equipment (mainly CNC equipment, including shearing machine, punching machine, flame cutting, plasma Cutting, high-pressure water) cutting and other traditional sheet metal processing equipment) have the advantages of high processing efficiency, high processing accuracy, good cutting section quality, three-dimensional cutting and so on.

Application of laser welding head in the processing of mobile phone parts With the continuous enrichment of functions of smart phones, the structure of mobile phones has become more and more complex. Engineers compressed a small area countless times to get the best design results. In the face of such complex processing, a slight unevenness will affect the operation of the entire phone. Therefore, in order to ensure the perfect embedding and integration of each component, it must be processed using a welding method with extremely high precision.

Laser welding heads are the most widely used laser welding technology in the automotive industry. In addition, there are laser marking technology, laser cutting technology and so on. It was first used for laser head welding of automotive gearbox gear sets. Use a 213KW CW co2 laser. Equipped with necessary cleaning, compaction, rotary table, laser, water cooling system, light guide system, protective gas system and online testing equipment. The whole set of equipment can weld two pieces per minute. Through long-term operation, a complete set of laser head processing management system has been formed, and a lot of work experience has been accumulated. The feasibility of the welding technology of automobile gear laser welding head has been fully affirmed by the manufacturer, and it has become a mature fixed technology in the automobile manufacturing industry.

Another typical example is PPS and LCP plastics. The transmittance of both materials to near-infrared laser light is very low. If both materials are filled with carbon black at the same time, laser welding cannot be performed because the laser cannot penetrate. Additionally, many mineral filler compounds are not suitable for laser head welding. In order to overcome these limitations of laser welding head welding, some plastic manufacturers are actively developing new materials, which help to improve the laser transmittance and absorption rate, and have made gratifying progress, bringing broader application prospects for laser welding heads .
