Low-melting-point metal material injection molding method, and machine for practicing the method

摘要

An injection molding machine includes a pair of injecting units. In each of the cylinder barrels of the injection units, a metal element having a melting point of 650 DEG C. or lower, or an alloy of such metal element is melted and measured by using heat which is externally applied thereto, and frictional heat, and shearing heat which are produced when the screw in the cylinder barrel is driven.
