A method of forming a consolidated component having a complex shape includes providing a first component having a first shape similar to the complex shape. The method further includes placing the first component in a chamber and surrounding the first component with a medium. The method further includes applying pressure and at least one of heat or electricity into the chamber to process the first component to form a consolidated component having the complex shape.

A method of forming a bladder cast ceramic matrix composite (CMC) article including infiltrating a CMC substrate positioned in a cavity of a mold body with a slurry. The CMC substrate includes reinforcement material defining inner spaces. The slurry includes solid particles and a carrier material. During infiltration, the slurry at least partially fills at least a portion of the inner spaces of the CMC substrate. The method also includes inflating at least one bladder that is coupled to the mold body and disposed within the cavity such that a surface of the at least one bladder in an inflated configuration contacts at least one surface of the CMC substrate. The method also includes drying the slurry to remove at least a portion of the carrier material form an infiltrated CMC and deflating the at least one bladder.

Crack-free powder-based, near net shaped parts are fabricated using a die assembly and cold isostatic pressing. Soft materials are introduced on both sides of die components in order to balance compression loads applied to the die component, and thereby avoid deformation of the die component.

Pressing arrangement (100) comprising a pressure vessel (1, 16, 17) and a furnace chamber (18) arranged therein defining a treatment region for an article (5), the treatment cycle including a cooling phase. The pressing arrangement (100) comprises a fan (35) configured to circulate a pressurised gas within the pressure vessel (1, 16, 17) and a heating device (36) for heating the pressurised gas in the treatment region. It further comprises a control and processing module (6) configured to, during the cooling phase: obtain temperature values in the treatment region; based on these values, determine a cooling power for cooling of the pressurised gas in the treatment region; determine a difference between a cooling power required to obtain a selected value of cooling rate of the pressurised gas and the determined cooling power; and based on this difference, control the fan's (35) rotational speed so as to make the difference decrease. If the cooling power provided by the operation of the fan (35) exceeds a cooling power corresponding to the desired cooling rate of the pressurised gas, the control module (6) is configured to, based on the determined difference, heat the pressurised gas using the heating device (36) to make the difference decrease.

A containment for use in hot Isostatic pressing, the containment comprising a body formed from sheet material and fused together along its longitudinal length using a backing strip on the outside of body. Also a containment with a body and top and bottom caps diffusion bonded upon hot isostatic pressing, a containment with a gas purge inlet and outlet and an apparatus for vacuum degassing are disclosed.

The present invention relates to an autoclave molding apparatus for use in molding a composite material composed of a fibrous base material and a matrix and sealed together with a molding tool in a vacuum bag, using steam for heating and compressing the composite material. The present invention provides an autoclave molding apparatus capable of effectively reducing the overshoot of the temperature of the composite material caused by poor dissipation of curing heat in a curing process and thereby capable of producing a composite material molded article having uniform and sufficient strength. More specifically, an autoclave molding apparatus of the present invention is characterized in that a condensed water holder(s) configured to hold condensed water generated by heating is mounted on at least a portion of the vacuum bag and/or at least a portion of the molding tool.

A method may include cold isostatic pressing a fused filament fabricated component comprising a plurality of roads and channels between at least some roads of the plurality of roads. The plurality of roads may include a sacrificial binder and a powder including a metal or alloy. The cold isostatic pressing reduces a presence of the channels between the at least some roads to form a compacted fused filament fabricated component. The method also may include removing substantially all the sacrificial binder from the compacted fused filament fabricated component and leave a powder component; and sintering the powder component to form a sintered component.

An assembly module includes a first assembly mold, a second assembly mold and at least one coupling mold. The first assembly mold has at least one first setup portion, the second assembly mold has at least one second setup portion, and the second assembly mold corresponds to the first assembly mold. The coupling mold is removably disposed at a position corresponding to the at least one first setup portion, at least one second setup portion, or the least one first setup portion and the at least one second setup portion. The coupling mold is provided with a limiting portion, and the first assembly mold or the second assembly mold is provided with a corresponding limiting portion. The coupling mold provides mutual corresponding limiting or anti-rotation against the corresponding limiting portion by using the limiting portion.
