Abstract
A rotatable electroplating barrel for electroplating articles, the electroplating barrel having a proximal end with a centrally formed aperture and a distal end with at least one helical rib extending circumferentially along a longitudinal axis and between the proximal end and the distal end. The at least one helical rib, proximal end, and distal end of the electroplating barrel are formed integrally as a unitary piece and have a contiguous perforated outer wall configured to couple directly to the proximal and distal ends, extending therearound to enclose the at least one helical rib.

A rotatable electroplating barrel for electroplating articles, comprising:
- a proximal end having a base and a raised internal surface with a centrally formed aperture therebetween, and at least one tab projecting from the base;
- a distal end;
- at least one helical rib extending circumferentially along a longitudinal axis and between the proximal end and the distal end;
- and
- a contiguous perforated outer wall coupled directly to the proximal and distal ends, extending therearound to enclose the at least one helical rib,
- wherein the at least one helical rib further comprises a radially extending flange having a pushing surface and a diametrically opposed trailing surface, the pushing and trailing surfaces extending between an axially extending outer surface and a diametrically opposed inner surface.

- wherein the at least one helical rib further comprises:
- a radially extending flange defining a height of the at least one helical rib, the radially extending flange having a pushing surface, trailing surface, and trailing edge;
- a channel projecting axially from the radially extending flange towards the proximal end and having a leading edge and an axial width defined by a distance between a plane defined by the radially extending flange and a plane defined by the leading edge;
- and
- a back surface diametrically opposed from the channel.
