ABSTRACT:
A die casting machine for manufacturing impellers made of Ni-, Co- or Fe-based heat resistant alloys. A die assembly which is provided with a plurality of radially retractable segments, is coaxially arranged and vertically movable with respect to an injection assembly. Die casting is effected in the lowermost position of the die assembly with the segments closed. The product is ejected out of the machine in the uppermost position of the die assembly with the segments retracted. A short runner minimizes heat dissipation of the molten metal and improves uniformity and quality of the product.
