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: The present invention is a weather strip having a body portion, and at least one elongated flange connected to the body portion. The elongated flange is operable with the body portion such that when the body portion is mounted in place in proximity to a wall member, the wall member applies a force to the elongated flange such that the elongated flange applies pressure to the wall member forming a seal between the elongated flange and the wall member. The weather strip of the present invention also includes at least one flexible member connected to the body portion, and the flexible member being is operable with the wall member such that the wall member applies a force to the flexible member and the at least one flexible member applies pressure to the wall member forming a seal between the at least one flexible member and the wall member.
