Abstract
Improvements in and relating to metal casting According to the invention there is provided a method of planning and controlling the low pressure casting of an object, such as a metal object, in a metal mould at a casting station, including the steps of: (a)determining the overall dimensions of the mould required to cast the object including the volume and/or density of the metal required to contain the object and absorb heat during casting and subsequent cooling via heat transfer to a cooling medium. (b)thereafter calculating the required pressure and upward flow rate of molten material from a holding crucible into the mould, (c)filling the mould with molten material from the holding crucible by applying an upward pressure to the molten material, wherein the pressure is variable in accordance with the size and shape of the metal mould as determined in step (b), (d)thereafter releasing the upward pressure on the molten material in the direction of the mould such that it returns to the holding crucible to be reheated or maintained at a required temperature, (e)thereafter removing the mould and continuing to cool the contents of the mould remote from said casting station until the cast object has solidified, and thereafter removing the cast object from the mould, the process continuing with successive empty moulds being placed in situ at the casting station for further casting of required further objects.
