Basic operations of a cold chamber die cast?

Molten metal is heated to its operation temp outside the chamber(shot sleeve) then poured in, piston forces molten metal into die cavity where it is held under pressure until it solidifies,The die opens and the plunger advances, to ensure the casting remains in the ejector die. Cores, if any, retract,Ejector pins push the casting out of the ejector half of the die and the plunger returns to its original position.
