3-D printed PLA material of a selected density is formed into a pattern that is configured as the outer shell of a casting form to be used in the lost foam or evaporative casting process. The purpose of 3-D printing of the PLA material is used to maintain the proper configuration of the form to facilitate casting, and reduce buildup of carbon on the surface of the casting. Because the form is essentially hollow, PLA support pieces can be used on the interior to maintain the structural integrity of the form.

A directional solidification casting assembly includes a directional solidification mold having an interior chamber with a shape of an object to be cast using directional solidification of molten metal in a growth direction of the mold and a feed line conduit. The conduit is fluidly coupled with a container source of the molten metal and is coupled with the mold at a gating. The feed line conduit conveys the molten metal into the mold through the gating for directional solidification of the object to be cast in the mold. At least a downstream portion of the feed line conduit that is between the intermediate location of the feed line conduit and the second open end of the feed line conduit is located below the gating along the growth direction of the mold.

Provided is a system for casting molten metals. The system includes a mould comprising a casting cavity having an inlet, and a bore between an upper surface of the mould and the inlet.

A device for producing a cylinder crankcase using a low-pressure casting method or a gravity casting method. The device includes an outer casting mold which includes at least one mold part which, in an assembled state, forms a mold cavity that reproduces, for casting purposes, an outer contour of the cylinder crankcase. A region of the mold cavity forms a cylinder space of the cylinder crankcase. A dosing furnace contains a liquid metal. At least one gate is arranged geodetically below the mold cavity and via which the dosing furnace can be fluidically connected to the mold cavity. Sprue bushings project into the region of the mold cavity that forms the cylinder space of the cylinder crankcase. Each of the at least one gate is connected to one of the sprue bushings.

A mould for casting a component in a directional solidification casting process having a preferred direction of grain growth (non-axial <001>) comprises a shell defining a cavity for receiving molten material. The cavity defines a three dimensional shape made up of a finished component geometry portion (42, 43, 44) and a sacrificial geometry portion (45) wherein the sacrificial geometry portion (45) includes a notch (48) which is shaped and positioned so as to, in use, contain high angle grain boundaries between dendritic growth in the preferred direction (non-axial <001>) and dendritic growth in a competing direction to the preferred direction (axial <001>) within the sacrificial geometry portion of a casting solidifying in the mould.

A modular spruing system apparatus contains a base section, a main sprue cone, a center rod, a plurality of trunk sections, a plurality of arm sections, and an end cap. The main sprue cone is mounted onto the base section. The center rod centrally traverses through the base section and the main sprue cone so that the user can design a spruing tree of desired height. A center rod receiving hole of each of the plurality of trunk sections allows the center rod to traverse through the plurality of trunk sections when removably attached to each other. Next, the plurality of arm sections is attached to the plurality of branch sections. The plurality of arm sections can be fixed or removably attached to the plurality of branch sections. When the desired height is reached, the plurality of trunk sections is fastened together with the end cap.

A high-temperature-resistant casting system comprises following casting elements in a connection relationship: a sprue cup (1) and a down sprue (2) connected with a lower end of the sprue cup, wherein the other end of the down sprue is connected with one end of a filtering element (6), the other end of the filtering element is connected with a three-way pipe (3), openings in two sides of the three-way pipe are connected with one end of an inlet section of a runner (4), and one end of an outlet section of the runner is connected with a tapered elbow (5).
