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 densify 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 is intended to improve a method for explosive forming of a workpiece by means of gas explosion, in which the workpiece is arranged in a intake area of a moulding tool, wherein the intake area is at least partially filled with liquid and the explosion is triggered by ignition of an explosive gas mixture, to the effect that the method is suitable and simplified for mass production. This object is solved by a method for explosive forming of a workpiece by means of gas explosion, in which the workpiece is arranged in a intake area of a moulding tool, wherein the intake area is at least partially filled with liquid and the explosion is triggered by means of ignition of an explosive gas mixture, in which the explosive gas mixture is provided at least partially above the surface of the liquid before the ignition.
