Abstract
1356330 Casting processes GRAVICAST PATENTVERWERTUNGS GmbH 3 Sept 1971 [4 Sept 1970] 41254/71 Heading B3F [Also in Division B5] In a method of casting in which melt 15 in a supply chamber 2 flows through a second chamber 5 to a mould 12 under the influence of its static pressure, the flow of melt into the second chamber 5 is interrupted when the chamber contains sufficient melt to fill the mould and a pressure higher than said static pressure is exerted on the melt in the second chamber and the mould when the latter has been filled. Control of the flow of melt into the second chamber 5 is effected by means of a stopper 9; this is held open until the chamber 5 and nozzle 11 are filled with melt and is then lowered to close the opening 8. After a pause the stopper 9 is raised again to permit the melt to flow into the mould at a controlled rate and in a turbulentfree manner. When the mould is full the opening 8 is again closed and an increased pressure applied to the melt by means of the piston 14, and held until the melt in the ingate of the mould has solidified.
