Abstract

Temperature influence to the injection of SS316L powder with particle size D50 of 11.225 μm and 19.606 μm mixed with PEG, PMMA and stearic acid binder system was investigated. The feedstocks were loaded with powder at 64 % V and 65 % V. Investigation discovered that the successful of the injection is depends on the feedstock rheological properties. Fine powder at low powder loading has higher sensitivity than the coarse powder feedstock. The investigation found that the injection temperature has its influence to the final quality of the compact. Injection temperature at 140 oC was the optimum injection temperature while the optimum powder is the fine powder as it gives high as-leached flexure strength and density when injection molded at 140 oC. However, the investigation does not found any significant on the injection temperature to the debinding rate
