Abstract
The invention relates to a method of using high velocity metal forming to encapsulate a projection of a non-metallic article by a metallic article and a method of crimping terminal flanges defining an interstitial space therebetween, while trapping a vapor barrier element between the terminal flanges, thereby hermetically sealing the interstitial space.
Claims20
A method of encapsulating at least a projection having first and second non-coplanar surfaces of a non-metallic article with a metallic article, the method comprising:
- arranging the non-metallic article and the metallic article to locate the projection within a corresponding recess on the metallic article;
- and
- encapsulating the metallic article onto the projection by applying at least one of a pressure wave and an electromagnetic field to form the metallic article about the projection such that the metallic article extends between the first and second non-coplanar surfaces and overlies each of the first and second non-coplanar surfaces.
A method of encapsulating at least a projection having first and second opposing surfaces of a non-metallic article with a metallic article, the method comprising:
- arranging the non-metallic article and the metallic article to locate the projection within a corresponding recess on the metallic article;
- and
- moving portions of the metallic article at a speed great enough where the portions flow plastically about the projection to encapsulate at least a portion of the projection.
