ar Method and apparatus for press casting By www.freepatentsonline.com Published On :: Tue, 14 Apr 2015 08:00:00 EDT An apparatus for press casting includes a casting mold formed of a fixed mold and a first moving mold operable to move relative to the fixed mold. The apparatus further includes a second moving mold operable to move relative to the first moving mold. A mold cavity, which forms a cast product, is configured by the fixed mold and the second moving mold. When the first moving mold is moved to a first predetermined position, a molten metal passage and a gas exhaust port, which communicate with the mold cavity, are formed at positions outside the mold cavity. A communication between the mold cavity and the molten metal passage, and the gas exhaust port is cut off by the second moving mold when the second moving mold is moved to a second predetermined position while the first moving mold is maintained at the first predetermined position thereof.

ar Method and apparatus for interlocking load carrying elements By www.freepatentsonline.com Published On :: Tue, 21 Apr 2015 08:00:00 EDT A method for interlocking structural steel components with a metal-filled interlock is disclosed herein. The method comprises placing a mold about aligned contoured portions of structural steel components and attaching a crucible and a spout to the mold. The crucible is charged with exothermic reactive metals which are ignited, forming a molten metal filler. The molten metal filler melts a metal plug in the crucible or spout and the molten metal filler flows into the mold and about the aligned contoured portions of the structural steel components. Cooling of the molten metal filler forms a metal-filled interlock. Molds for performing the disclosed method are also disclosed herein. Full Article
ar Tower pump casting apparatus By www.freepatentsonline.com Published On :: Tue, 05 May 2015 08:00:00 EDT A casting apparatus having a main chamber connected to at least one casting tower. The main chamber may contain molten metal and the temperature within the main chamber may be maintained by a furnace. A pump may pump the molten metal up the tower and into an upper pool chamber. A feeder nozzle may feed the molten metal from the upper pool chamber and onto a chilling wheel, which may turn the molten metal into metal flakes. Full Article
