Publication number: 20220260050Abstract: A system for manufacturing a panel includes a support frame, a first caul plate arranged atop the support frame, a second caul plate arranged atop the first caul plate, and a heating assembly having a housing defining an inlet and an outlet. The housing includes one or more heaters. The heater(s) is configured to generate heat and the housing is configured to generate a first pressurized gas film. Thus, one or more layers of material to be consolidated may be placed between the first and second caul plates and drawn through the heating assembly as the heating assembly applies pressure to the one or more layers of material to be consolidated via the first pressurized gas film in combination with applying the heat via the one or more heaters, thereby consolidating the panel.Type: ApplicationFiled: July 16, 2019Publication date: August 18, 2022Inventors: James Robert Tobin, Andrew McCalip, Lauren Laurer Watts, Hongyi Zhou, Huijuan Dai, Collin McKee Sheppard

Publication number: 20160271691Abstract: A method involves filling a hydrogen-lean molten material in a crucible and closing a lid of the crucible and then feeding a first quantity of a compressed dry gas via the crucible to form a dry gas blanket on a surface of the hydrogen-lean molten material. The method further involves feeding a second quantity of the compressed dry gas to a mold assembly to purge the mold assembly and transferring the hydrogen-lean molten material via an opening of the lid of the crucible to a mold cavity of the mold assembly. The method further involves cooling the hydrogen-lean molten material to form a casting.Type: ApplicationFiled: March 16, 2015Publication date: September 22, 2016Inventors: Alexander Kagan, Adegboyega Masud Makinde, Duncan Spalding Pratt, Huijuan Dai, Longzhi Jiang, Qi Zhao
