Abstract:
1. A method of making a fluid filter, comprising the steps of: aligning first and second plastic housing shells in contact with one another to form a housing having a central axis, said first and second plastic housing shells each having an end portion and outer wall depending from said end portion to define a portion of an internal cavity wherein a seam area is defined in an area where the first and second housing shells contact one another, said outer walls of said housing shells substantially surrounding and enclosing a filter element without contacting the filter element; heating said outer walls of the first and second housing shells proximate the seam, such that the first and second housing shells are fused together to form a housing; and moving molten plastic material from the seam area, inwardly to contact the filter element, such that the filter element becomes fixed in position in the housing by molten plastic material from the seam area.
