Abstract

The molten metal is forced into the die by a hollow outer plunger (I) the bore of which forms a cylinder contg. a second, coaxial plunger or piston (II). Inert gas is fed into the inner cylinder and functions as a 'cushion' during the initial part of the feeding stroke and then as a booster at the end of this stroke. The inert gas is fed into the inner cylinder at a press. of pref. 50-500, esp. 100-150 bar, and piston (II) is free to slide in the bore of plunger (I) without coming into contact with the molten metal. Provides reduced stress on the dies, giving longer die-life, and sounder casting due to the efficient boost.
