The apparatus for removing investment material from an investment flask casting includes a spring-biased seating assembly, a centering assembly having spring-biased shoulder mounts, a vertical impact assembly, and a pair of opposing horizontal impact assemblies. The vertical and horizontal impact assemblies work simultaneously and in combination with the spring-biased seating assembly and the spring-biased shoulder mounts to transmit linear dynamic and high frequency vibratory impact energy to the investment flask casting wherein the apparatus effectively and quickly removes virtually all of the investment material therefrom. The investment apparatus further includes an investment collection system for collecting waste investment material for subsequent disposal.
