Metal Injection Molding (MIM) process is capable to produces varieties of intricate shape and complex geometry parts in large quantity components at low cost of processing. There are four Major steps in MIM process which is includes of mixing fine metal powders with plastic binder to form a feedstock, injection molding of the green part, extracting the binder, and finally sintering. Thus this paper are concentrate on investigate the processability of Natural Hydroxyapatite and Stainless Steel (SS316L) mixture with an established binder formulation as a feedstock in MIM. The Natural Hydroxyapatite (NHAP) was produced from waste Tilapia Fish Bones. While, Polyethylene (PE) and Palm stearin (PS) acted as a binder system. NHAP/ SS316L mixture was successfully injected and established as an appropriate feedstock in MIM. The green strength of ejected part was determined. The maximum force that could attach is 48.1719 N and the maximum stress equal to 6.02Mpa.
