Abstract

A filter assembly includes a filter housing configured as a singular unitary component defining a fluid flow passage through the filter assembly. A filter element is fixed within the housing and spaced apart from both ends of the filter housing to filter a fluid as the fluid flows through the filter housing. A method of insert molding a filter assembly includes providing a mold shaped to form the filter housing as a singular unitary component, locating a filter element in the mold at a location corresponding to where the filter element is to be fixed within the filter housing, and injection molding a molten plastic filter housing material around the filter element such that a portion of the filter element is encapsulated by the molten plastic filter housing material to form the filter housing in a manner that bonds the filter element in place within the filter housing. The filter assembly alternatively may be made by 3D printing the filter housing around the filter element.
