A foundry mold includes at least one molding cavity and one pair of feeder arms. The molding cavity extends, along a horizontal axis, from a first end to a second end, and the first pair of feeder arms comprises a first feeder arm, oriented in a substantially vertical direction and connected to the first end of the first molding cavity, and a second feeder arm, substantially parallel to the first feeder arm and connected to the second end of the first molding cavity.

A process for high integrity castings of metals and their alloys includes the steps of providing at least a sand mold at desired elevated temperatures, delivering a molten metal into the mold, and supplying a predetermined amount of coolant to contact the surfaces of the casting at desired rates, times, and durations to achieve an acceptable level of progressive solidification from the distal end of the casting towards the riser until the casting has reached desired temperatures.

A hybrid core for manufacturing a cast component, the hybrid core including a sand core portion having an exterior shape configured to define an interior feature of the cast component. The hybrid core also includes a metal chill element embedded within the sand core portion. The metal chill element is configured to locally absorb heat energy from the cast component during cooling of the cast component and solidification thereof. The metal chill element is constructed and arranged within the sand core portion to be removed during shake out from the cast component subsequent to the solidification thereof. A system and a method for manufacturing a cast component using such a hybrid core are also envisioned.

A cast part includes an outermost wall, at least one inner wall defining at least two internal passages and at least one cast cooling fin extending from an outer surface. The cooling fin includes a ratio of fin height to an average fin thickness that is greater than 2.0 and no more than 18.0. A method is also disclosed.

A casting method includes: forming a seed, the seed having a first end and a second end, the forming including bending a seed precursor; placing the seed second end in contact or spaced facing relation with a chill plate; contacting the first end with molten material; and cooling and solidifying the molten material so that a crystalline structure of the seed propagates into the solidifying material. The forming further included reducing a thickness of the seed proximate the first end relative to a thickness of the seed proximate the second end.

Disclosed is a preparation method of a foamed aluminum special-shaped part. The preparation method comprises the following steps: S1, pressing wax molds; S2, making a shell; S3, carrying out smelting; S4, carrying out casting; and S5, vibrating the shell. Finally, the foamed aluminum special-shaped part is obtained for a preparation process of a foamed aluminum compound casting.

A casting method includes forming a seed. The seed has a first end and a second end. The forming includes bending a seed precursor. The seed second end is placed in contact or spaced facing relation a chill plate. The first end is contacted with molten material. The molten material is cooled and solidifies so that a crystalline structure of the seed propagates into the solidifying material. The forming further includes inserting the bent seed precursor into a sleeve leaving the bent seed precursor protruding from a first end of the sleeve.
