A study of the comparison of `Vʹ and `Xʹ ribbing in a composite pedal using mold flow analysis software

This paper presents a comparison study using mold flow analysis software for a polyamide-reinforced composite clutch pedal. The main interest is to see the effects of increasing gate number on fill time, pressure distribution, and weld line and temperature. The second interest lies in the comparative study on the gating effects mentioned above for `Xʹ and `Vʹ ribbing. This paper illustrates the use of computer simulation as a basis to develop the mould for the clutch pedal. It also provides an insight to unforeseen problems commonly related to injection molding process such as weld line and warpage.
