Abstract
A filter element, for placement in a housing of a filter system, includes a filter medium pack and a seal arrangement having a seal and a seal carrier. The filter medium pack includes, for example, a pleated filter medium or a fluted filter medium. The seal carrier includes an axial side coupled to at least a portion of an axial face of the filter medium pack by a thermal welding manufacturing process. The coupling of the seal to the seal carrier is obtainable by manufacturing the seal arrangement with a multi-material injection molding manufacturing process. The present disclosure further relates to a method for manufacturing a filter element, the method including steps of thermal welding and multi-material injection molding.
