Abstract
A highly stressed casting vessel for hot-chamber pressure diecasting machine is provided with a cast-in, correspondingly bent pipe as the ascending bore which is welded together from three parts, in which case two different elbow parts which are connected with a straight pipe piece may each individually be adapted to the locally occurring requirements. Thus, the high-expenditure finishing and pressure losses of the flowing molten baths associated with inserted cores used in producing the ascending bore are avoided.
