  • Method for obtaining near net shape castings by post injection forming of wax patterns
    Patent number: 5339888
    Abstract: The invention relates to a method of producing near net shaped metals parts from shaped wax patterns and more particularly a process whereby control of the wax pattern shape from which metal parts are to be investment cast is accomplished by machining the wax pattern after injection forming.
