Abstract
An electroplating barrel comprises a rotatable, perforated barrel for holding objects to be electroplated. The barrel defines at least one access aperture for access to its interior, plus means for imposing an electrical potential across electrolyte solution within the barrel. In accordance with this invention the access aperture has aperture-defining edges, the edges occupying planes which are at an acute angle of about 10.degree. to 80.degree. to the plane of the aperture they define. Accordingly, door members shaped to fit each access aperture and defining correspondingly angled edges may close the access aperture without forming significant spaces between the door members and the aperture-defining edges.
