Abstract: A method and apparatus for forming a soap bar from remnants of used soap bars. A molding base defining an internal molding cavity is provided with a pivotal closure also defining an internal die cavity. A forming die is movably supported by the closure and is movable from a retracted position out of the molding cavity to an extended position within said molding cavity where the forming die applies mechanical pressure to the soap fragments. The forming die is receivable within the die cavity at its retracted position and has a concave die surface of a configuration for forming a portion of the soap bar. A die actuator extends through the closure and may be provided with a spring for retraction of the die or for urging the die in a direction for continuous application of molding force to the forming die for a sufficient period of time for adhering and forming the soap bar fragments so as to define a resulting soap bar for subsequent conventional use.

Abstract: A plastic molding apparatus and method employs a pair of dies having at least one cavity with a mirror surface and wherein a plastic base material which is pre-molded is inserted into the cavity and clamped by the pair of dies. The plastic base material is then heated and melted at glass transition temperature or higher so that a resin internal pressure is generated, and then the plastic base material is annealed so that the mirror surface is transferred to the plastic base material. One of the dies has a separation die in which the cavity is formed. A cavity forming portion thereof has a cavity forming surface and a cavity side board portion which is adjacent to the cavity forming portion and surrounds the cavity forming surface. A separating die clamping structure clamps the separation die from both sides so as to compress an elastic member mounted between the cavity forming portion and the cavity side board.

Abstract: Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a highly inorganically filled matrix. Suitable inorganically filled mixtures are prepared by mixing together an organic polymer binder, water, one or more aggregate materials, fibers, and optional admixtures in the correct proportions in order to form an article which has the desired performance criteria. The inorganically filled mixtures are molded to fashion a portion of the mixture into a form stable shape for the desired article. Once the article has obtained form stability, the article is removed from the mold and allowed to harden to gain strength. The articles may have properties substantially similar to articles presently made from traditional materials like paper, paperboard, polystyrene, plastic, or metal. They have especial utility in the mass production of containers, particularly food and beverage containers.

Abstract: A mold assembly for molding an elastomeric sealing element onto an annular seal case includes a spring-biased outer sleeve that exerts a clamping force on the seal case during the molding cycle. During the mold closing stroke the leading edge of the sleeve engages the seal case before an uncured elastomeric charge reaches the seal case. The sleeve therefore acts as a flow barrier to limit any outward escape of elastomer from the mold cavity during molding. By isolating the clamping and flow limiting outer sleeve from the hydrostatic molding forces, the spring force applied to the outer sleeve may be reduced and the axial height of the mold assembly may also be reduced.
