Abstract:
A flow formed part includes a first end, a second end, and a side wall extending therebetween. A reinforcing member is disposed around the second end. The side wall has a profile formed along an inner surface of the side wall. The profile is adapted to be substantially burr free after windows are formed in the sidewall. A method of making a flow formed part includes the steps of disposing a preform on a tailstock, providing a plurality of rollers adjacent the tailstock, providing a mandrel having an outer surface including a plurality of alternating channels and protuberances, and causing the rollers to press the preform against the outer surface of the mandrel.
