Applications of Direct Metal Casting Process on Low-cost Rapid Tooling
Aimed at the problems of direct metal casting powder with expensive sale price and high production cost because its raw material production technology was protected by patent, a low-cost preparation method of direct metal casting powder with the mass ratio of 6 ∶4 by mixing 74 μm Al2O3 powder and 37 μm gypsum powder ZP102 was identified. And the fast molds of gear and elbow were successfully printed using the low-cost direct metal casting powder,then qualified castings of gear and bends were produced, so as to greatly reduce the cost of print materials in direct metal casting technique.
