Abstract
The shot sleeve of the invention is used in a die casting machine and defines a bore for containing molten metal to be injected into a die. At least one passageway disposed generally parallel to the bore for containing a first fluid having a fluid temperature and a fluid flow rate is provided, whereby substantially uniform temperatures can be maintained across the width of the shot sleeve by controlling the fluid temperature of the fluid flow rate or both the fluid temperature and the fluid flow rate. A die casting machine and an associated method are also disclosed.
