Production of Composite Parts of H13 and 316L by Two Components Injection Molding

Abstract

A new development in MIM aims at the manufacturing of parts out of two materials, the Two Components Injection Molding, which allows the production of parts with different materials in distinct locations, obtaining different properties in distinct regions of the part. In this work an austenitic stainless steel was combined with tool steel, based on the Two Components Injection Molding process, using dilatometric experiments to analyze the behaviour of materials during sintering. Metallographic analyses and tensile tests were made to verify the microstructure and the strength in the contact area of the two materials.
