Patent ID: 6938669

Claim:
A method for molding metal by conveying metallic material with a screw within a hot runner heated to a predetermined temperature, charging the heated metallic material in a semi-melted or liquidized state at a tip end of the hot runner, injecting such metallic material into a mold cavity, and cooling the material to mold a metallic mold product, wherein the method further comprising a gate-melting process for heating the metallic material solidified in a tip end portion of a nozzle of the hot runner, a mold-lubricant coating process for spraying a mold-lubricant onto a wall surface of the mold, and a material-metering process for metering the metallic material are carried out simultaneously in parallel to each other between a mold-clamping process for closing the mold and an injection-pressure increase process for injecting the metallic material into the mold.
