Properties of MIM 4140 Alloy After Injection Molding and Sintering
Journal Title: International Journal of Innovation Engineering and Science Research - Year 2018, Vol 2, Issue 1
Abstract
Testing results of a multi-cavity mold for injection molding of MIM 4140 alloy are presented in the article. Recommendations for manufacturing of forming parts of the mold were given. Based on an implemented technological process of casting and subsequent laboratory researches an information was obtained about the condition of a casting (hardness on Super-Rockwell, shrinkage and quality of a surface layer of material before and after heat treatment). Calculated overall dimensions of the forming parts of the project mold will allow making forecast of shrinkage of MIM 4140 alloy after injection molding.
