A method is provided for casting a component. Accordingly, a casting core is provided within a cavity of a component mold. The casting core defines an inner component shape and includes a core wall. The core wall defines a core outer surface and a core inner surface disposed opposite the core outer surface. The core inner surface defines a core cavity. The casting core also includes a removal facilitation feature. The component is cast within the cavity of the component mold with the casting core positioned therein. The cast component is removed from the component mold and the casting core is removed from the cast component.

Embodiments described herein provide a fastening device such as a nail or staple having at least one projection each extending away from the body at an angle and away from a tip of the body. For example, in the case of a nail, there can be two or more projections extending from the elongated member of the nail each at a substantially equal distance from the head and/or along the length of the elongated member each spaced at substantially equal distances apart. In the case of a staple, there can be at least one projection connected to the interior surface of a first leg of the staple, that surface being substantially opposite to an interior surface of a second leg of the staple. The tip can be sharp or not sharp. The projections can be connected to exterior surfaces of the staple's legs.

Integrated core-shell investment casting molds that provide tongue or groove structures corresponding, respectively, to groove or tongue structures in the surface of the turbine blade or stator vane, including in locations that are otherwise inaccessible provide a pathway to restrict cooling flow between turbine blades to the flowpath.

A mould-forming and sacrificial materials are printed into a plurality of layers. The sacrificial material is removed to leave a void defined by a mould structure formed by the mould-forming material. The void is filled with a part-forming material to form the part defined by the shape of the mould structure. The mould structure is removed from the part to free the part from the mould structure. According to a further method, the part-forming material serves the purpose of supporting the mould-forming material and then forming the part. In this case, the part-forming material can be printed together with a mould-forming material as described above and are then heated to a temperature of approximately 700° C. to activate a binder and then heated to a temperature that melts the part-forming material.

Methods and systems for creating a mold for a cast memorialization product are described herein. In a process for creating a mold, a three-dimensional (3D) model of a product design is generated. The product design includes customized features for a memorialization product. A mold design is generated based upon the 3D model of the product design. Printing instructions for creating the mold are generated and accessed by a processing device. The mold is created according to the printing instructions. A product, such as a bronze memorialization product, can be cast using the mold.

A casting mold (6) consists of two mold halves (4, 5), which are intended for setting up on both sides of the welding groove (3) between two rail ends (1, 2) to be connected, thereby forming a casting space (8) representing a cross-sectional profile of the rails. For sealing the casting space (8) between the rail bodies on both sides of the welding groove (3) and the wall portions (9, 10) of the casting mold (6) that are facing this welding groove, inserted in gaps (11, 12) are strips consisting of a compound at least containing expandable graphite, which as a result of heat being supplied during a preheating process expands and forms a reliable seal. In comparison with using filler sand at this point, there is the advantage that a much smaller quantity of compound has to be carried along when working on the laid track.
