Characterisation of stainless steel 316L and palm stearin based binder by using metal injection molding (MIM) process

Polystyrene (PS) has been a nature’s degradable issue as it cannot biodegradable. In this project, recycle polystyrene (PS) is used as main binder in Metal Injection Molding (MIM). The research aims are to investigate the optimum injection parameter for stainless steel 316L with polymeric binder (PS...
