Abstract: A removable housing component for attachment to an aerosol generation device housing is provided. The component includes first and second ends, the component extending between the first and second ends to define a component axis, a concave inner surface, the surface having a concave profile in a direction along the component axis, and a first plurality of elongate protrusions extending from the concave inner surface and spaced apart from each other in the direction along the component axis. An aerosol generation device including a housing is also provided.

Abstract: A method of manufacturing a housing component for an aerosol generation device includes injection molding a housing component between first and second die parts. The first die part has a concave surface so as to form a convex surface on the component during the molding, the concave surface of the die having a first texture which imparts a corresponding texture on the convex surface of the component during molding, wherein the first texture includes a variable roughness across the concave surface of the first die part. Also provided are housing components for an aerosol generation device, the housing components having convex surfaces with textures.
