APPARATUS FOR DIE-CASTING METALS

摘要

Die-casting apparatus, primarily for casting ferrous metals, including a shot duct formed from two or more longitudinally successive structurally separate components which may be made of respective different materials or of the same material, in either case selected to suit the operating conditions to which they are exposed. The components are supported partly by one of the dies and partly by a casing such that the degree of tightness of interference between the casing and the components supported therein is selected to provide a controlled degree of radially outward conduction of heat thereby to control the operating environment of the components.
