“…The mixing condition used, was barrel temperature of 170 8C, blade speed of 65 min À1 , and time of mixing of 30 min for all samples. At the beginning of the mixing, a high resistance to rotation of the mixer blades was noted which was also observed in the former studies [22]. As the time passed, the torque of the mixer started to decrease and became stable after some time.…”

Metal injection molding is a growing technology for producing complex metallic components. Preparation of feedstock for metal injection molding is a very crucial step during this process. This is because the deficiencies in quality of the feedstock once made, cannot be corrected by subsequent processing steps. One of the challenges in producing the feedstock is its formulation. In this study, the effect of the percentage of carnauba wax along with other binder constituents of paraffin wax, polypropylene and stearic acid is investigated on the density, strength, hardness and rheological behavior of a part, made of 4605 low alloy steel powder using metal injection molding process. For this reason, six binder systems including paraffin wax, polypropylene and stearic acid having different percentages of carnauba wax have been produced. After preparation of the samples, tensile testing, Vickers hardness test, density and rheological behavior of the samples have been measured and compared. The results show that carnauba wax as a part of feedstock, has a positive effect on the strength and density while negative effect on the hardness of the final sintered part. Also with the increase in the percentage of the carnauba wax inside the polymer binder, the viscosity of the feedstock was reduced significantly.

“…For example, the M n of PHBV was reduced to 68% of the value for the starting polymer when processing in the mini‐extruder but only to 92% of this value when processing in the internal mixer. This finding may be due to the higher thermal impact on the polymer when processing in the mini‐extruder 14. Changing from air to a flow of nitrogen in the mini‐extruder did not significantly influence PHBV degradation when processing without clay.…”

However, when blending with Cloisite20A, PHBV degradation was to some extent determined by whether processing occurred under air or nitrogen.…”

“…A similar twin-screw mixer has been also used by Pogodina et al (2008) to determine the shear rate and viscosity from batch mixer data. They found out that when the binder and metallic powders are introduced in the mixing chamber, it offers a certain resistance to the blades rotation and therefore the torque increases.…”
