ABSTRACT:
Molten metal is either poured or injected into the cavity of a permanent mold by way of a bush which comprises a metal sleeve, anchored to the mold itself, a first tubular element of ceramic material lodged internally of the sleeve, and a second tubular element, also ceramic, coaxial with the first. The stream of metal passes from a feeder into the inlet end of the bush, through the first and then the second ceramic element, and enters the cavity ultimately from an outlet end consisting of a metal annular element connected in a precise and effectively fluid-tight fit with the corresponding end of the second tubular element.
