Abstract:
The end caps of a filter element are formed on the element by dispensing a photo-initiated polymer in a transparent mold, setting the end of the filter media array in the mold, exposing the mold to ultraviolet light for a time sufficient to cure the polymer, and then stripping the mold from the finished end cap. Accordingly, the time of 60-75 seconds required to cure prior art Plastisol end caps is reduced to a few seconds necessary to cure the end caps made from the photo-initiated polymer. The end caps have been designed with reinforcing ribs to minimize the amount of polymer required while still maintaining necessary hoop strength to retain the media in place.
