Research on Rapid Manufacturing Technology of Complicated Casting Mold without Pattern

Abstract:

In 21th century, the product upgrading becomes faster and faster. The development of varieties of production needs rapid manufacturing technology. The rapid fabrication of sand mold & core is the key of rapid casting. In this paper, the rapid manufacturing technology without pattern was applied to produce the complicated sand molds & cores of pump case. The digital precision forming technology without pattern casting was selected to mill the outer sand mold. And the Selective Laser Sintering (SLS) technology was used to print the sand core. So the complicated sand molds and cores were fabricated rapidly without pattern. As a typical digital manufacturing technology, the rapid manufacturing technology without pattern has a variety of benefits such as short cycle, low cost, flexibility and so on. The technology that combines the sand milling and SLS provides a high-efficiency method for the Single and small batch castings.
