ABSTRACT:
A process for potting hollow fibers within a body is disclosed wherein a bundle of hollow fibers is formed within a hollowed portion of the body such that the fibers are substantially aligned and uniformly spaced. A molten thermoplastic composition is dispensed into the body at a contact temperature below the melting point of the hollow fibers. The bundle and the body are both at a temperature which is sufficiently low enough to cause solidification of the molten composition substantially upon contact with the bundle. A pressure differential is applied to the body to assist the flow of the thermoplastic composition around each of the hollow fiber elements such that the bundle and the interior of the hollowed portion of the body are encapsulated by the thermoplastic composition thereby assuring reliable sealing between the hollow fiber elements and the interior of the hollowed portion of the body.
