This research describes the effect of processing parameters as matrix feeding speed, screw rotational speed and cylinder temperature of direct fiber feeding injection-molded process on properties of short glass fiber reinforced polyoxymethylene composite. The increasing of matrix feeding speed at screw rotational speed of 172rpm led to the reduction of fiber loading content and increasing of fiber length. Whereas the higher screw rotational speed impacted on the increasing of fiber loading content and fiber length. However, its tensile properties were lower than the molded at screw rotational speed 172rpm. When fiber loading content over 20wt.%, tensile strength of both conditions reached the same values because the poor fiber distribution especially at screw rotational speed of 258rpm. Then Kelly – Tyson's equation was used to predict their tensile strength. It was found that tensile strength at maximum fiber loading content at screw rotational speed of 172rpm and 258rpm are lower than the calculated strength values around 28.9% and 31.8%, respectively. The effect of cylinder temperature was also elucidated
