I have a plug finished with wrapped edge. it is a car front lip part. As you can see in the attachment, it has a basic flat surface when you view from top. But from a vertical cut view, the edge on the front wrapped down and back about 2cm. I have the plug finished, but having a difficult time to create the mold from it. please give me some suggestions.

thanks.

I'll vote for the one piece mould too.
Big flanges.
Vac infuse the part.
