The Applications of Mold Flow Analysis on Vibration Separation Technologies of Investment Casting Components

Article Preview

Abstract:

Conventionally, the investment casting components were separated from the casting pattern tree via a grinding machine to cut off ingate/inlet of the gating system. This post-treatment process may considerably increase labor and material costs. In this paper, a fatigue damage technology was proposed to separate the components in substitution for the cutting operation of traditional grinding machines. Mold flow analyses were conducted in the design of the gating system to ensure the casting quality. An actual vibration experiment of the casting pattern tree was conducted, and the results verified that the substitutive scheme is feasible.
