Process Parameters Used in Macro/Micro Powder Injection Molding: An Overview

Powder injection molding (PIM) is a well-known manufacturing technique for the production of complex, net-shaped macro-parts using a broad range of materials and alloys. Eventually, the PIM method has been modified into micro-powder injection molding (mu PIM) because of the increasing demand of micro-parts in global market. Now-a-days PIM and mu PIM processes are extensively using to fabricate components for electronic, automobile, and biomedical fields. In this paper, the important process parameters that had been used to fabricate defect-free macro and micro-sized parts of different metals, ceramics, and alloys using the above-mentioned techniques have been reviewed. This article is enclosed with a brief discussion on the future research guidelines addressing different aspects related to the two-component macro and micro powder injection molding. This paper could be a worthy source for those investigators who aim to work on PIM and mu PIM technology.
