Wuhan Shengtongli Technology Co., Ltd. is a high-tech company that integrates product development, design, production and sales of laser equipment and supporting systems. We are committed to laser and laser solutions. We only focus on laser marking, laser cleaning and laser welding process. At present, the company's self-developed products include: YAG fiber transmission energy negative feedback welding system, pulsed fiber laser welding system, laser welding splitting system, fiber laser arbitrary power control system, energy fiber, gold-plated reflection cavity, CCD system, laser welding and so on. Laser cleaning is the use of laser as a medium, through the interaction of light and matter, to achieve the purpose of removing pollutants. Laser cleaning is an emerging surface cleaning technology, which is more in line with the current needs for environmental protection and social sustainable development. At present, many types of laser cleaning equipment have been developed and successfully applied in industrial cleaning, and good benefits have been achieved. The laser marking machine uses a laser beam to mark a permanent mark on the surface of a variety of different substances. Marking effect is through the evaporation of the surface material to expose the deep material, so as to carve out a beautiful pattern, trademark and text, laser marking machine is mainly divided into CO2 laser marking machine, semiconductor laser marking machine, fiber laser marking machine and YAG laser marking machine, laser marking machine is mainly used in some requirements of more fine, higher precision occasions. Laser welding machine mainly through high-temperature fusion, the two materials are perfectly combined together, strong and beautiful appearance. In the new energy power battery cover, sealing and cleaning has a perfect solution.
