Abstract: Particulate bearing precursor components are formed into intricate shapes yet possess controlled porosity by injection molding a mixture of particulate materials, thermosetting condensation resins, and low temperature catalysts. The mixture, when flowed into a mold cavity of an appropriate shape and heated, initiates a curing reaction which binds particulates together with a film that leaves the space between the particulates open. A positive volume change occurs during cure, providing for a more uniform pressure profile in the part. Also, a condensate is produced during the curing step which, when vented from the mold in strategic locations, allows manipulation of the curing reaction. This provides the ability to affect local density in the vicinity of the vent. Thus, one can correct for artificially, or incorrectly induced density or porosity gradients, and improve dimensional accuracy and other attributes of the subsequent processing steps.

Since the molded calcium silicate articles have a superior workability and a good thermal dimensional stability, they are very useful especially in the preparation of molds or models where high levels of processing precision and thermal stability are required.

Abstract: A method and apparatus for injection molding of ceramic suspensions is disclosed wherein an elastomeric bladder is disposed within a mold cavity of a mold. The elastomeric bladder, in a relaxed state, can be tubular or can be formed by bonding together sheets of material.
