Abstract
A mandrel comprising a surface effective for electroforming an article thereon, wherein a portion of the mandrel has a contoured surface effective for facilitating axial movement away from the mandrel of the article formed thereon when the article experiences circumferential motion relative to the mandrel.
Claims9
A process comprising:
- (a) forming an article on a mandrel comprised of a contoured surface, wherein the article overlays the contoured surface of the mandrel, thereby resulting in the article comprised of a corresponding contoured surface, wherein the contoured surface of the mandrel defines:
- (i) two opposed planes, at least one of which is inclined;
- (ii) a first flat region curving into a first raised region and a second flat region curving into a second raised region;
- (iii) a screw thread;
- or
- (iv) one or more grooves;
- and
- (b) subjecting the article to circumferential motion relative to the mandrel, wherein moving the corresponding contoured surface of the article over the contoured surface of the mandrel self-generates axial movement of the article away from the mandrel.
