ABSTRACT:
An injection molding system includes a feeder in which a metal is melted and a first chamber into which a desired amount of melted metal is introduced. A piston in a second chamber first retracts to create suction, assisting in drawing in the melted metal into the second chamber from the first chamber and evacuating gas. A ram then pushes some melted metal remaining in the first chamber into the second chamber, forcing out gas present in the second chamber. The piston then injects the melted metal out of the second chamber into a mold. The melted metal is preferably maintained in a liquid state throughout the system.
