Laser welding machine application in mobile phone stainless steel screw nut - Shenzhen Sun Laser

With the high speed growth of China's economy, people's living standards are also greatly improved, their demands for mobile phones is also growing. This also drives the market for mobile phone nuts. The mobile phone nut is usually made of SUS304 stainless steel, which has the features of excellent rust prevention performance and high mechanical strength.

The main function of the mobile phone nut is to connect the plastic parts and metal parts, or to connect the metal parts with the metal parts for fastening. The stainless steel nuts are generally connected to the mobile phone stamping parts or other artifacts by means of rotary riveting, pressure riveting and the like.

However, the rotary riveting method is uneconomical, and the pressure riveting method is easy to cause deformation and other effects on other components. While the laser welding has the advantages of high energy density, high welding efficiency, small heat influence and little deformation. It adopts non-contact welding method, not influenced by workpiece size and shape, it can implement long-distance rapid welding, which is very suitable for nut welding of mobile phones.

The welding principle of mobile phone nut stud Laser welding machine is based on laser high thermal energy and centralized fixed point welding technology, the surface heat is diffused into the inside of workpiece, by controlling the width, energy, peak function and repetition frequency of the laser pulse, a specific molten pool is formed on the workpiece to achieve the welding effect.

The stainless steel metal laser welding machine of Shenzhen Sun Laser is a Laser welding equipment that couples high-energy laser beam into optic fiber, after long-distance transmission, collimates into parallel light through collimating lens, and then focusing on the workpiece for welding. It is more flexible to implement non-contact welding on the inaccessible parts.
