چکیده مقاله
In this study, we demonstrate the injection stage of Metal Injection Molding MIM process to fabricate a small bend type component This non standard but critical engine part is made of a feedstock from the low alloy steel 4605 To optimize various injection parameters, the five variable Box Behnken Design BBD is used with the assumption of a quadratic model, together with the statistical method of Response Surface Methodology RSM Samples are then fabricated and their densities are measured Hence, the significance of these factors as well as the mutual coupling between each two parameters are investigated using the analysis of variance ANOVA Finally, this paper reveals that injection temperature of 155 ◦C, the injection speed 80 mm/s, holding pressure of 83 bar, holding time of 9 s and the injection pressure of 132 bar lead to an optimum density of the green part, which becomes 4 892 g/cm3 Then, a new sample is produced using these optimized settings, and the green component density is measured, which is extremely near to the predicted value
