A mask that communicates a flow of breathing gas with an airway of a user is formed by a two-shot injection molding process. The mask includes a mask body and a mask seal member, at least a portion of which is molded to the mask body by a two-shot injection molding process while the mask body is cooling and incompletely cured. The mask seal member, or a portion thereof, is molecularly bonded to the mask body as a consequence of the two-shot injection molding process. |
