  • Patent number: 8690229
    Abstract: The invention provides a method of manufacturing a cowl top cover, which can easily adjust a reaction force of a first seal portion, and ensure sealing performance in a lip part. A main body cavity is formed in a part of a cavity by moving a slid core forward in a guide hole and making it contact with a second die. A cover main body is molded by injecting a synthetic resin into the main body cavity. A slide core is moved backward by a predetermined distance in the guide hole so that the thickness of a lip part in a lip protrusion becomes smaller than that of the lip part in a second seal portion. The lip part is molded by injecting a synthetic resin softer than that forming the cover main body into a seal portion cavity.
