Increased flow capacity filter

A method for molding an end cap onto pleated filter media of a filter element, said pleated filter media having a plurality of pleats in a closed loop having an outer perimeter defined by a plurality of outer pleat tips, and an inner perimeter defined by a plurality of inner pleat tips, said loop having a hollow interior extending along a given axis, wherein fluid to be filtered flows laterally through said filter media, and flows axially in said hollow interior, said filter element having an axial flow passage extending along said axis and circumscribing said hollow interior and having a flow perimeter greater than said inner perimeter, said method comprising providing a mold having a trough extending along a first perimeter and holding liquid castable material therein, providing an upstanding dam on said mold extending along a second perimeter circumscribed by said first perimeter, dipping axial ends of said pleats into said liquid castable material and engaging said axial ends of said pleats against said dam at a location between said outer pleat tips and said inner pleat tips such that said dam impedes flow of said liquid castable material laterally inwardly towards said inner pleat tips.
