Abstract: A method for producing dental restoration components includes filling a retort cylinder of a retort system with a forming mass, the retort cylinder being at least partially encircled by a charging body, and hardening the forming mass. After the hardening of the forming mass, the retort cylinder and the charging body are removed from the forming mass, thereby leaving behind a retort. Thereafter, with the assistance of a press blank apparatus, a press blank having an outer contour substantially corresponding to the outer contour of the charging body is pressed into the retort.

Abstract: In the method, after the pattern-bearing film is fed to the female mold, the distal end of the film is fixed under a lower portion of the female mold, and at the same time the film is retreated by a force from the film supply portion. Thus, this tightens up the film so that the slacks or wrinkles cannot be formed on the film. Therefore, the film can be fortunately spread around the parting surface of the female mold. In the apparatus, the film suppressing frame is pressed to the female mold through the sliding rod arranged in the female mold, in such a manner that the female mold embraces the frame. Thus, the pressing of the frame is performed by a simple structure, and the film is accurately positioned to the internal surface of the female mold. Also, the film suppressing frame is constituted to advance from and retreat to the female mold. Thus, this causes a space between the both molds and an outside standby position to be useless. A space around the apparatus can be effectively utilized.

In the interlock ring 4, a plurality of openings 4a which relieve gas produced by the disc resin material filled into the cavity 6 are formed.

Abstract: An injection molding machine includes a plasticating unit for plasticating a thermoplastic resin, and an injecting unit connected to the plasticating unit through a connecting passage to inject the plasticated resin into a mold. In the connecting passage, provided is a buffering unit for reserving the resin in an amount at least equal to the quantity of the resin injected per one shot. The plasticated resin is temporarily reserved in the buffering unit, and then, the reserved resin is fed to the injecting unit when the measuring is carried out, whereby the plasticating unit can be driven continuously simultaneously with the operation of the injecting unit and the mold. The molding cycle can shortened with the plastication efficiency being enhanced.

Abstract: A device suitable for use by children which recycles broken crayons and other materials by melting and molding. A stationary melting pot securely retains the charge material during heating. A housing substantially surrounds the melting pot and an associated mold chamber to isolate young operators from all heated surfaces. The melting pot is charged from outside of the housing by use of a filling port. A remotely operated gate controls the flow from the melting pot to a mold. A door provides access to the mold when open and prevents access to the mold chamber when closed. A warning light glows when a heating element for the melting chamber is energized. Various safety switches interrupt power to the heating element if certain conditions are not met.
