Abstract
The present specification is directed a method manufacturing a patient interface for treatment of sleep disordered breathing using air pressure by delivery of air to a patient's airway. The method includes locating a shell, a first sub section of a seal forming structure, and a first section of the seal forming structure in a tool. The first sub section includes a groove. The first section is constructed from a thermoformable material. The method further includes introducing a moulding material to the tool and overmolding the shell, the first sub section, and the first section. The moulded material forms a second sub section of the seal forming structure that connects the first sub section to the shell and fully encloses the first section within the groove.
