Injection Temperature

In this paper, injection molding parameters are optimized using the L18 Taguchi orthogonal array for mechanical strength and surface quality of the green part. The feedstock used consists of stainless steel powder (SS316L) with the powder loading of 63 vol. %, 63.5 vol. % & 64 vol. %. The binder compositions used are polyethelene glycol (PEG-73 wt.%), polymethyl methacrilate (PMMA-25 wt.%) and stearic acid (4 wt.%). Mould temperature, injection temperature, injection pressure, injection time, holding time and powder loading ware selected as signal factors using Taghuci’s method based on literature, where these parameters were significant in MIM. Results showed that the optimum parameters are: mold temperature at 650C, injection temperature at1450C, injection pressure at 650 bar, injection flow rate at 20 m3/s, holding time at 5 s and powder loading of 64 vol.%. Analysis of Variance (ANOVA) result shown that mold temperature is the most influence in order to produce good green part’s surface quality while powder loading give the best result for green part’s strength.

Processing Stage

This paper deals with the mechanical properties of test specimens of commercially available PIM feedstocks based on a stainless steel powder. After injection molding, a part of the polymer binder has been removed in water. This process was followed by thermal removal of residual binder and sintering at 1360 °C in hydrogen atmosphere. For production of the mechanical test bars fresh and recycled feedstocks were employed. The aim is to determine the changes in mechanical performance resulting from injection molding processing stage, especially possible separation of feedstock components – the stainless steel powder and the polymer binder
