A method and apparatus for making molded structures using a mold and a moldable material is disclosed wherein a substantially smooth finish is provided to the material at an open surface of the mold. The material is released into the mold through a feeder opening comprising an inner door and an outer door displaceable in a plane substantially parallel to the opening. A combined activation of the doors controls a flow of the material from the feeder to the mold. When the mold has been filled and both the inner door and the outer door are closed, the outer door may be reopened to smooth the material at the open surface of the mold. Alternatively, a feeder opening may comprise a single door and a relative displacement between a mold support supporting the mold and the door may be used to provide a like effect. A mold comprising an outer tray and a resilient inner mold fitted therein, the outer tray comprising holes in a bottom wall thereof to provide access to a bottom face of the inner mold is also presented for use in the present invention.
