摘要： A method of forming metal castings, including positioning a first end of a structural member in a first mold cavity and a second end of the structural member in a second mold cavity. The first and second mold cavities being fluidly coupled to a reservoir of molten metal. Applying a main pressure to the molten metal in the reservoir to force the molten metal into the first mold cavity and the second mold cavity. Then, applying a first auxiliary pressure to the first mold cavity and a second auxiliary pressure to the second mold cavity to density the casting formed in the first mold cavity and the second mold cavity. Also, a method for casting including maintaining a main pressure at or less than an initial, mold-filling pressure after first and second mold cavities have been filled. Additionally, a method for detecting whether a first mold cavity is sufficiently filled with molten metal by monitoring a moveable element.

摘要： The invention concerns a composite casting comprising:
a steel member;
an end cap fastened to an end portion of the steel member; and
a cast coupling member cast about the end portion of the steel member including the end cap, thereby positively and rigidly locking and securing said cast coupling member to said steel member.
The invention also concerns an engine cradle for a motor vehicle, comprising:
a frame assembly having a pair of spaced rails secured by spaced cross members;
at least one of said spaced rails and said spaced cross members including a composite casting, including:
a steel member;
an end cap fastened to an end portion of the steel member; and
a cast coupling member cast about the end portion of the steel member including the end cap, thereby positively and rigidly securing the cast coupling member to the steel member.
The invention also concerns a composite casting comprising:
a steel member;
an end cap fastened to an open portion of the steel member; and
a cast coupling member cast about the end cap of said steel member by casting-in-place aluminum about said end cap, thereby positively and rigidly securing said coupling member to said steel member.
