Abstract
A hot stretch wrap forming die typically includes a rigid backing section, a series of spaced ribs extending forward from the backing section, and an elongated face sheet secured to the ribs forward of the backing section with a convex forward-facing die face. The ribs elastically deflect during thermal expansion of the face sheet when a heated metal bar is forced against the die face so that the metal bar transfers heat to the face sheet. The die typically includes stiff ribs secured to the backing section and the face sheet which provide substantially fixed points for the face sheet during its thermal expansion. The face sheet may include several face sheet segments which together form the die face. The face sheet may also include contour plates which form respective portions of the die face and which may be used to adjust the specific contour of the die face.
