摘要： An aluminum-magnesium alloy is disclosed which provides superior properties for casting in steel dies and good ductility for forming castings of complex shapes, including thin-wall portions. The aluminum-based alloy contains, in weight percent, about 2-15 percent magnesium, 0.2 to 3 percent silicon, 0.05 to 0.5 percent chromium, 0.05 to 0.5 percent manganese, 0.05 to 0.2％titanium, and a minimal content of iron. In its molten state this aluminum-magnesium-chromium alloy can be pushed into the molding cavities of iron-based dies in a high pressure die casting procedure and conform to complexly-shaped die surfaces with thin cavity portions without dissolving appreciable amounts of iron or experiencing die soldering on the die surfaces. The resulting castings display good strength and ductility and can be further enhanced by an artificial aging process after solution heat treatment.

摘要： A method of casting an article includes closing a die set (22), which defines a casting cavity (30) and a gate cavity (32). A pressure actuated valve (54) is closed to block fluid communication between the casting cavity (30) and the gate cavity (32). A vacuum system (34) is engaged to remove air and form a vacuum in the casting cavity (30). A molten material (46) is introduced into the gate cavity (32). The molten material (46) is compressed in the gate cavity (32) to increase a fluid pressure of the molten material (46). The pressure actuated valve (54) is opened when the fluid pressure of the molten material (46) in the gate cavity (32) reaches a predefined pressure level, to allow fluid communication between the gate cavity (32) and the casting cavity (30). The molten material (46) is pushed through the gate cavity (32) and into the casting cavity (30) under pressure to form the article (28). A die casting system (20) is also disclosed. The method allows the vacuum system (34) to remove more air and gasses from the casting cavity (30), prior to the molten material (46) being introduced into the casting cavity (30), thereby reducing porosity in the final cast article (28).

摘要： A method of manufacturing a pin(46) for a mold(28) includes forming the pin(46) to include a substantially uniform initial hardness throughout the entire structure of the formed pin(46). The formed pin(46) is then processed with a hardening process, such that the processed pin(46) exhibits a hardness defining a hardness gradient that gradually increases from the initial hardness at a central interior region(56) of the pin(46) to an increased surface hardness at an exterior surface(60) of the pin(46). After processing the pin(46) with the hardening process, a coating(64) maybe deposited onto the exterior surface(60) of the pin(46) with a physical vapor deposition process. The coating(64) exhibits a hardness that is greater than the hardness of the increased surface hardness of the exterior surface(60) of the pin(46). The pin(46) may include, for example, a core pin, a squeeze pin, or an ejector pin.
