“…Ethylene-vinyl acetate (EVA) is a good secondary binder component since it has high strength and can serve as backbone polymers during debinding. It has been used as backbone in several studies [9][10][11]. Carnauba wax (CW), a natural wax formed on Brazilian palm leaves, acts as a lubricant and mould releasing agent inside the feedstock.…”

In this study, the effect of polypropylene (PP) as the backbone polymer of Metal injection moulding (MIM) feedstock has been investigated on the micro-structural phase constituents, mechanical and rheological properties of 4605 low alloy steel compacts. For this purpose three binders systems consisting of paraffin wax (PW), stearic acid (SA) and carnauba wax (CW) having different contents of PP (20, 24 and 28 mass %) were compounded. The sintered samples were then tested for mechanical (tensile and hardness), micro-structural (Xray diffraction (XRD) and scanning electron microscope (SEM)), density and rheological (viscosity) properties. The results show that an increase in the PP percentage results into the improvement of mechanical and physical properties while decreasing the rheological properties. From the microstructure point of view it was observed that the amount of PP, is directly related to the residual carbon content of the sample which affects the grain size, total porosity and phase constituents.

“…The metal manufacturing industry is currently interested in developing metal powder technology for production cost efficiency. One of the applications of metal powder technology is as a feedstock for metal injection molding (MIM) (Suharno et al, 2019;Supriadi et al, 2019). MIM can produce lower surface roughness values compared to investment casting (Suharno et al, 2018).…”

The low-cost plasma atomizer in the present study successfully synthesized stainless steel spherical powder using an energy source of less than 3 kVA. Repeated testing was conducted to examine the resulting spherical powder, among other observations, using a digital microscope (Dino-Lite AM4115), scanning electron microscopy (SEM-FEI-Inspect F50), and energy dispersive spectroscopy (EDS). To ensure the purity of the resulting 316L stainless steel spherical powder, EDS was used for qualitative and quantitative elemental analysis. The results showed that the 316L stainless steel spherical powder particles varied in size from 26 µm to 180 µm with average particle diameters of approximately 82.6 µm, making them ideal for biomedical applications. The results of the feed metal flow rate on the powder weight percentages for particle sizes <50 µm for 2 mm 3 /s feed metal flow, 3 mm 3 /s feed metal flow, and 4 mm 3 /s feed metal flow were 26.04%, 28.04%, and 13.09%, respectively. It is possible that this could occur because greater metal flow rates require greater plasma energy to form liquid metal droplets, so that a lower metal flow rate at the same energy consumption makes it possible to produce more metal powder in smaller particles.
