MULTI-COMPONENT COMPOSITION METAL INJECTION MOLDING

摘要

A method of metal injection molding on a plastics injection molding machine having a heated barrel with an increasing temperature gradient is disclosed. The method comprises the steps of providing a metal alloy feedstock including a first metal alloy with a first melting point and a second metal alloy with a second melting point that is higher than the first melting point, the first metal alloy and the second metal alloy providing a gradient in composition of solids to liquids paralleling the temperature gradient of the heated barrel, feeding the first metal alloy and the second metal alloy into the plastics injection molding machine, heating the first metal alloy and the second metal alloy within the plastics injection molding machine to about 500-700° F./260-372° C.; and forming an equilibrium of about 5% to about 30% solids to liquids between the first metal alloy and second metal alloy within the heated barrel.
