Methods for forming a unitized crucible assembly for holding a melt of silicon for forming a silicon ingot are disclosed. In some embodiments, the methods involve a porous crucible mold having a channel network with a bottom channel, an outer sidewall channel that extends from the bottom channel, and a central weir channel that extends from the bottom channel. A slip slurry may be added to the channel network and the liquid carrier of the slip slurry may be drawn into the mold. The resulting green body may be sintered to form the crucible assembly.

A process for manufacturing a composite part includes arranging a fibrous preform in a mold including an impregnation chamber which includes in its lower part a filter by making a first face of the preform rest on the filter, the impregnation chamber being closed by a flexible membrane placed opposite a second face of the preform, the membrane separating the impregnation chamber from a compaction chamber. The process further includes injecting a compression fluid into the compaction chamber so as to apply a first pressure on the membrane and injecting a slurry including ceramic particles into the impregnation chamber with a second pressure while maintaining the injection of the compression fluid, the second injection pressure of the slurry being lower than the first pressure on the membrane.

Methods and apparatus are provided for pressure casting ceramic bodies. Methods and apparatus are provided for rapid ejection of cast ceramic bodies from a mold. A mold is described that has an impermeable cavity surface to provide dry release of the cast body. Ceramic bodies produced by the methods and apparatus have smooth, non-tacky surfaces after ejection from the mold

A slip casting mold is useful for producing a ceramic die cast part. The slip casting mold includes a first mold part with a first main part and a first filtration layer and comprising at least one second mold part with a second main part and a second filtration layer. The first main part is equipped with at least one first dewatering channel with at least one dewatering channel end that opens into a second dewatering channel within the second mold part or into a dewatering channel within an additional dewatering body in a casting position.

A plumbing fixture includes an electrical component insert-molded within a portion of the plumbing fixture, the portion formed from an epoxy. The electrical component is offset from and disposed below an outer surface of the plumbing fixture.

A method of forming a toilet assembly includes casting a flush engine from vitreous material, installing a functional insert on the flush engine, placing the flush engine in a mold, and inserting a material in the mold to create a cavity with the functional insert.

Molding unit for the production of sanitary wares, comprising at least one support frame, at least one first portion and one second portion associated with the frame, bearing respectively at least one first molding component and one second molding component selectively connectable to each other, so as to define at least one molding cavity adapted to receive the casting of at least one pressurized fluid mixture which, once solidified, forms at least one sanitary ware. The first portion and the second portion are connected to the frame in the hanging configuration and are able to be selectively and mutually approachable in a closed configuration, so as to bring into mutual contact the molds to define the molding cavity, and mutually movable away from each other in an open configuration to allow the removal of the sanitary ware once formed. At least the first portion comprises clamping means selectively movable from an inactive position, corresponding to said open configuration, to an operating position, corresponding to said closed configuration, in which they act on at least one abutment zone provided in the second portion.

A toilet assembly includes a flush engine having a bowl, a sump at a lower portion of the bowl, and a trapway extending from the sump. The toilet assembly further includes a first polymeric layer at least partially surrounding the flush engine, the first polymeric layer comprising a foam. The toilet assembly further includes a second polymeric layer provided on the first polymeric layer, the second polymeric layer comprising resin.
