Laser rapid manufacturing technology makes up for the shortcomings in the laser sintering process. The application of modern laser technology adopts a specially developed laser irradiation scheme that has been patented and protected. It uses a standard steel powder as a raw material technology and has achieved great success. It can produce a shrink-free, almost 100% dense zero. component. Large parts can now be made using genuine raw materials, such as a strongly cooled mold core. The properties of the materials used are the same as those used in mass production, so that the manufactured parts meet the conditions for mass production. The aluminum alloy foundry uses this process technology to manufacture die-casting molds for aluminum alloy materials for automotive production plants.
Application of new fields
Laser rapid manufacturing technology is a mass production manufacturing technology in the automotive manufacturing industry. It is the interface for the transition between the product sample test and the batch test in automotive mold manufacturing. For mold manufacturing plants, the advantages in terms of quality and economy are obvious:
(1) After using a cooling core close to the contour surface of the workpiece, the production efficiency of the die-casting mold is significantly improved.
(2) The optimized cooling effect greatly reduces the deformation of the casting.
(3) Reduced shrinkage and shrinkage of castings, significantly improving the quality and function of die castings.
(4) It is possible to pre-machine a mold core with a complicated contour shape.
(5) The use of laser rapid manufacturing technology to manufacture mold cores takes less time and is more automated.
(6) The programming cost of the laser rapid manufacturing process technology is reduced to a minimum, and the flexibility is greatly improved.
(7) A hybrid manufacturing method with patented technology can produce a large mold core. This also expands the application of laser rapid manufacturing process technology in the field of mold and tool manufacturing.
