 They want the battery of laser pointer can be used longer.
The advantages of laser transformation hardening hardness than conventional quenching, small deformation, surface thin layer and partial quenching does not affect the mechanical properties of the substrate. Laser shock processing of laser shock processing is a high power density, short pulse laser beam and material interaction of strong shock waves to change the technology of surface physical and mechanical properties. In the process of laser shock due to the dynamics of laser induced shock wave peak stress than the material yield stress, so that the material to produce a dense, uniform and stable dislocation structure, the metal surface of the plastic deformation and the formation of deep residual compressive stress , thereby increasing the strength of the metal parts, wear resistance, corrosion resistance and fatigue life. The size of the battery of laser pointer isΦ17.0×33.5(mm).
Its main advantages are: the impact of high pressure, strengthen the depth of a traditional shot peening depth of four to eight times; parts that can not handle processing of traditional crafts, such as slots, holes and contour of the class; laser peening of metal surface distortion and mechanical damage, heat stress injury, does not cause phase transformation. 3) laser alloying of laser alloying and laser cladding technology and laser cladding material to a layer of mold matrix composition with a certain performance coating in the mold matrix, coated with high-energy laser beam region. Laser alloying the coating material and part of the matrix by adjusting the laser output power with the melting and alloying process occurs. The working temperature of the battery of laser pointer is -10℃－+60℃. It can automatically and quickly design ideas materialized with a certain structure and performance of the prototype or the direct manufacture of parts. Applied to the mold design can be any complex shape of the mold samples Rapid Manufacturing applications from a single model-making to the development of rapid tooling and rapid casting, multi-purpose direction, allowing for rapid evaluation of the mold design, modify. The customer uses and maintains the battery of laser pointer well. It is the 3000 hour life time of laser module of laser pointer .
The design is complete, the model in a computer using specialized software format, cut into thin slices and the STL format. The thickness of each layer is determined by the operator in the region requiring high precision usually thinly. Computer to each layer is divided into vector data grid control binder spray head moving direction and speed. Ceramic powder with a special powder spreading device Spreading in the piston on the table. Powder roller leveling drum level, and control the thickness of the powder after flatten equal to the thickness of the corresponding layers in the computer model. Computer-controlled jet head layered vector mesh data to be scanned, and spray adhesive.
