Abstract

A hot chamber die casting apparatus for casting aluminum, zinc, magnesium, copper and their alloys as well as other metals which, in the molten state, corrode ferrous materials. The apparatus comprises a crucible, an injection pump in the crucible, and a gooseneck leading from the crucible to an outlet nozzle. The parts of the apparatus have coatings or sleeves of materials which resist corrosion, abrasion, erosion and mechanical or thermal shocks.
