Abstract

A hot stretch wrap forming apparatus includes a die having a work surface formed of a thermally and/or electrically insulative material, and a set of spaced jaws for stretching and wrapping the metal form around the work surface. A preferred insulative material is a flexible blanket of woven ceramic fibers. A heat source is used to heat the metal form prior to stretching and wrapping. The metal form is preferably heated resistively to maintain a uniform temperature throughout the metal form. The die is typically formed primarily of metal and thus the insulative material thermally insulates the metal form from the metal of the die to prevent the formation of hot spots which would otherwise occur therebetween. The insulative material also electrically insulates the metal form from the metal of the die to prevent shunting therebetween.
