摘要：

The warpage of injection-molded plastic parts is a complex problem being affected by different technological parameters, material properties, and mold design. Hence, the description of the deformation is difficult as well. This article presents the effect of fiber content and mold temperature difference on the deformation of polypropylene parts. Based on the measurement results, a linear approximation and a calculation method are shown, which can be used to jointly determine the ideal fiber content and mold temperature difference to produce undeformed plastic parts.
