Abstract
An apparatus for centrifugally casting a rectangular access floor panel includes a turntable, a drive for rotating the turntable about a generally vertical axis in a generally horizontal plane, and a mold clamped to the turntable. The mold is vibrated during rotation to insure void-free distribution of a lightweight concrete mixture throughout a metal pan retained within the mold. A hopper and an auger feed the concrete mixture to the mold through a sprue. The mold retains corner pads and silencer buttons. The corner pads cooperate with pedestal heads to eliminate the need for stringers.
