| Summary: | Metal Injection Moulding (MIM) is one of the recognizing near net-shape forming technologies for metals,
cermets and ceramics. Solvent and thermal debinding is a crucial step For the technical and cost practicality of
this process and quality of the obtained products. This paper presents an experimental study of two step
debinding process oF SS316L feedstock base on Fats, Oils and Grease (FOG) derivatives binder as lubricants
and surfactant compound with polypropylene as backbone binder. Effect of solvent debinding variables an
the shape maintenance of the green compact were studied. After solvent debound, the brown part will
undergo thermal debinding process under air atmosphere with various temperature and heating rates.
Differential Scanning Calorimeter (DSC) were used to confirm the extraction of the FOG derivatives
constituents completely form the binder mixture. Scanning Electron Microscopy (SEM)/Energy Dispersive X-ray Spectroscopy(EDS) was used to see the pores in the green and brown bodies created after solvent and
thermal debinding process which allowing for subsequent process of sintering. Energy Dispersive X-ray
Spectroscopy (EDS) was used to monitor the carbon and oxygen contents results from the thermal debinding
process |
