VALIDATION OF A HIGHLY THERMALLY CONDUCTIVE IRON-COBALT- NICKEL ALLOY AS TOOL MATERIAL FOR INJECTION MOLDS

摘要

With injection molding the tool is the basic component of the process. For applications in which a high distribution of heat is required or particular value is placed on good molding accuracy it is necessary to use tool materials with a higher thermal conductivity. Previous materials can be replaced by an iron-cobalt-nickel alloy with increased thermal conductivity, high strength and a thermal expansion behavior the same as steel. The laboratory for applied plastics technology of the University of Applied Sciences Schmalkalden, Germany (Fachhochschule Schmalkalden) has had the opportunity to investigate and evaluate a new type of iron-cobalt-nickel alloy with regard to its suitability as tool material for injection molds.
