Direct Extrusion of Bulb Seal on Cowls

By directly extruding a bulb seal onto an air-inlet panel (cowl), the application's functional requirements are met and time-consuming manual installation of the seal is eliminated as a secondary operation.  An extrusion die, mounted to a flexible, heated hose and guided by a robot, quickly and efficiently lays down a TPV profile along the edge of the injection-molded substrate.  The fully automated process creates an easily tunable and functional seal that can be handled immediately after extrusion without need for post cure (as with thermoset rubber).  The operation is cost-effective, eliminates a secondary operation, maximizes sealing to the hood interface with excellent dimensional stability, reduces scrap, and provides high design freedom and process flexibility.
