Appl. No.:

10/125354

Inventors:

Carmella Ferouz - Rockville MD
Brian Bayne - Odenton MD
Joseph Kim - Frederick MD
Stephen B. Rowland - Laurel MD

Assignee:

PerkinElmer, Inc. - Wellesley MA

International Classification:

F16L 1706

US Classification:

277609, 277616

Abstract:

A flange and seal assembly is provided with an annular sealing ring and a mounting component. The annular sealing ring is retained as a part of the mounting component. The mounting component has a mounting end with a mounting flange extending outwardly from the mounting end, and an annular seal receiving recess formed in an axial end surface of the mounting end, and a retaining element extending from the mounting end. A portion of the sealing ring is axially retained between the retaining element and the axial end surface of the mounting end.

Abstract:

There is disclosed a plating process that involves the application of a soft metallic coating, composed of substantially pure metal or alloy, to resilient metal seals utilizing a high-volume, high-energy electro-deposition plating process. The process basically includes supporting a predetermined quantity of metallic seals at non-sealing surface locations with the metallic seals disposed in series on a conveyor having a predetermined processing path, and continuously moving the seals in series through an electro-plating stage of the processing path to electro-deposit a metallic coating on the seals using a high current density and a high chemical flow rate. The seals of this process are applicable to any application or industry where a large quantity of high vacuum/high purity seals are required and where traditional electro-deposition processes would not yield a sufficient quantity of finished parts or would not produce them at an acceptable cost.
