Replication of metal microstructures by micro powder injection molding
AbstractIn this paper, a study on the production of 316L stainless steel microstructures by μPIM (powder injection molding) is presented. Two types of mold inserts were used and the molding was conducted on a conventional injection molding machine. Based on the characteristics of the mold inserts and the feedstock, suitable processing parameters were selected. Some requirements for the production of the microstructures are discussed. For example, a relatively high mold temperature, high injection pressure and holding pressure were required. The study showed that 316L stainless steel microstructures of φ100×200 μm can be injection molded, but there were incomplete filling and demolding problem in the case of smaller microstructures of φ60×191 μm. The molded parts were successfully debound and sintered.
