| Chp. 10: Overview Of The Investment Casting Process |
chapter 10 metal casting applications clinton l. atwood overview of the investment casting process investment casting, often called lost wax casting, is regarded as a precision casting process to a complete description of the process is beyond the scope of the discussion here, the sequential steps of the investment casting process will be briefly described, with emphasis on casting from rapid. fabricating the injection die often costs tens of thousands of dollars and can require several months of lead time. once a wax pattern is produced, it is assembled with other wax components to formapplied. fig. 10.1. investment casting process description. once the ceramic has dried, the entire assembly is placed in a steam autoclave to remove most of the wax (fig. 10.2a). after autoclaving,n metal, creating the metal casting (fig. 10.3a). once the casting has cooled sufficiently, the mold shell is chipped away from the casting. next, the gates and runners are cut from the casting, and description (cont'd.) fig. 10.4. cad solid model (top), ceramic shell with quickcast pattern (left), quickcast pattern (right). the major impact rapid prototyping processes have had on investmento fabricate a complex pattern in a matter of hours and provide a casting in a matter of days. investment casting is usually required for fabricating complex shapes where other manufacturing processes
