Abstract: Method for making multiple durometer bulb seals and any other types of multiple durometer seals and moldings includes cooling separately at least one structural member and at least one sealing portion, which have different durometers and shapes. At least a first extrusion is drawn through an extruder, forming a structural member profile and the extruded material is pulled along a longitudinal axis to a first calibrator device and first cooling tank to cool the structural member profile to a predetermined temperature. Cooling medium directly contacts the outer and inner surfaces of the first profile. Downstream, the sealing portion is extruded and affixed onto the cooled structural member and pulled further downstream to a second calibrator device and through a second cooling tank to cool the final profile a predetermined amount. Disparity in cooling expansion and cooling differential between the multiple durometers and shapes is avoided or overcome.

Abstract: Method for making multiple durometer bulb seals includes cooling separately at least one structural member and at least one bulb portion of the bulb seal, which have different durometers and shapes. At least a first extrusion is drawn through a die of an extruder for forming a structural member profile and the extruded material is pulled by a first pulling device along a longitudinal axis to a first calibrator device and then through a first cooling tank to cool the structural member profile to a predetermined temperature. Cooling medium directly contacts the outer and inner surfaces of the first profile. The bulb portion is extruded and attached onto the cooled structural member and pulled downstream to a second calibrator device and through a second cooling tank to cool the profile a predetermined amount.

Abstract: A reinforced extrusion for attachment to a motor vehicle component edge or flange. The reinforced extrusion includes a reinforcement core having at least one flexible wire and at least one threaded cord. A thermoplastic overmold is formed on at least one side of the reinforcement core and at least partly fills any gaps formed in the reinforcement core. An extruded layer is selectively formed around the thermoplastic overmold and reinforcement core and has a flange extending flange portion extending from a channel portion for engaging a motor vehicle component. The thermoplastic overmold helps prevent the reinforcement core from showing through to any visible show surface of the reinforced extrusion.
