摘要： A feedstock delivery system for injection molding includes a vessel unit that includes a vessel with an internal volume and an inlet for receipt of a feedstock. First and second dispensing units are alternatively connectable to the vessel unit and each include first and second ends, first and second valves, and a buffer chamber. The first end is connectable to the dispensing unit such that the buffer chamber is in communication with the internal volume of the vessel. The second end is connectable to an injection mold and defines an outlet of the feedstock delivery system. The outlet is in communication with the buffer chamber, and the buffer chamber is positioned between the first and second valves. The buffer chamber of the first dispensing unit defines a first chamber volume, and the buffer chamber of the second dispensing unit defines a second chamber volume greater than the first chamber volume.

摘要： A method is provided in which a lower box comprising a base, walls that surround the base and an open side, and an upper box comprising a cover, walls that surround the cover and an open side are provided. One or more objects are arranged on the base of the lower box. The object(s) are covered with the upper box such that the open side of the upper is oriented towards the base of the box, the walls of the upper box are arranged on the base of the lower box and a gap is formed between the walls of the upper box and the walls of the lower box. A powder material is introduced into the gap in order to form an assembly having an interior. The powder material provides a mechanical obstacle to gas exchange between the interior and the environment. This assembly is then heat treated.

摘要： A method of fabricating a burner element for an abatement apparatus is disclosed. The method comprises: injection moulding a charge comprising metal particles and a flow compound into a mould defining the burner element to produce a moulded burner element; and sintering the moulded burner element. In this way, injection moulding is used to produce the burner element, which provides far more flexibility regarding the design and properties of the burner element and avoids the necessity of incorporating a perforated support into the burner element. This allows burner elements of more intricate design to be produced, as well as burner elements which are thinner than those produced using existing techniques, which increases the volume of a combustion chamber defined by that burner element for any external burner element size, which in turn increases the amount of effluent gas that can be treated for any burner size.

摘要： A method of manufacturing a shroud segment for gas turbine engine includes providing an insert having a plurality of pins that extend into a platform cavity portion of a mold cavity. A powder injection molding feedstock is injected. When the green part is disengaged from the mold, each elongated feature is slid out of the green part to define a respective elongated cooling passage in the platform. The method may include, after debinding and sintering, projecting a coating material while defining an obstruction between source of coating material and the open end of each elongated feature with a shoulder of the element to prevent the coating material from reaching the open end, followed by machining to remove at least a part of the shoulder.

摘要： An example sinter system includes a sinter gas inlet at a sinter furnace for a sinter gas, a tracer gas inlet at the sinter furnace for a tracer gas different from the sinter gas, and an outlet at the sinter furnace to output the sinter gas and the tracer gas. The example sinter system further includes: a support structure to support a sample green object in the sinter furnace, an opening at the support structure connected to the tracer gas inlet, the opening to output the tracer gas into the sinter furnace, and a detector to: determine an amount of the tracer gas flowing through the outlet during a sinter process as a sample green object positioned on the support structure changes shape during the sinter process with respect to the opening and modifies a flow rate of the tracer gas to the outlet; and determine when to stop the sinter process based on a determined amount of the tracer gas.

摘要： A system includes a plurality of building trays, a printing station, a powder delivery station, a powder spreading station, a process compaction station and a stage. The printing station prints a mask pattern on each of the plurality of building trays. The powder delivery station applies a dose of powder material on each of the plurality of building trays. The powder spreading station configured to spread the dose of powder material on each of the plurality of building trays. The process compaction station compacts the powder material. The stage concurrently advances the plurality of building trays to each of the stations to concurrently build a single layer on each the plurality of building trays and repeats the advancing to build a plurality of layers on each of the plurality of building trays. A three dimensional object is formed in each of the building trays.
