ABSTRACT:
An improved shot sleeve for molding molten metals has a surface pattern of copper for passively distributing heat from a well opening in the sleeve side wall. Molten metal is poured into the well and is discharged along the internal sleeve bore and longitudinally out from the sleeve into a die means by a water-cooled piston. The improvement involves a surface pattern of copper to produce lower operating temperatures by conducting and radiating heat away from the well. The benefits are longer plunger life and longer sleeve life.
