摘要： A process is described for welding sheet material (12) comprising a thermoplastic polymer. The process comprises overlapping edges (20, 22) of the sheet material to form a lap joint, supporting the lap joint on an anvil (14), and welding the lap joint by contacting and traversing the lap joint with an ultrasonic welding horn (18). The welding horn is oscillated at a frequency of between about 30 kHz and about 45 kHz while contacting and traversing the lap joint with the welding horn. The welding horn is preferably highly thermally conductive.

摘要： A cylindrical electroforming mandrel and method of fabricating and using same, the mandrel having a substantially cylindrical mandrel core having substantially parallel sides and at least on tapered end (91) having curved sides which converge toward an apex, and a plated metal coating (94) on the parallel sides and the tapered end, the profile of an axial cross section of the tapered end from the intersection between the curved sides and the parallel sides to about the apex having the shape of half an ellipse defined by the formula:
y = ±b/a√(a²-x²)
where
a = ½ the length of the major axis of the ellipse and has a value between about 2.3b and about 1.7b.
b = ½ the height of the minor axis of the ellipse and has a value at least about 1,000 times greater than the thickness of said plated metal coating on said parallel sides, and
x and y define a point lying along the outer surface of the ellipse measured from the center of the elipse.
