ABSTRACT:
An apparatus and method for testing the flow characteristics of molding compounds includes upper and lower mold portions movable relative to one another. The lower mold portion has formed therein a central cavity and a channel extending therefrom with scribe marks formed on a bottom wall of the channel. The upper mold portion has a complimentary raised area for cooperation with the cavity and the channel to force molding compound placed in the cavity to flow down the channel providing an indication of the flow characteristics of the molding compound. Ejector pins positioned in the bottom of the cavity and the channel are actuated by an ejector pin plate which is coupled to the upper mold portion to eject the sample when the mold portions are separated.
