Abstract
A method is provided for producing a fuel tank of a motor vehicle, with an insulation applied to an outer side of a fuel tank container by application of foam, wherein the fuel tank container is placed into a foam-encapsulating mold and at least partially encapsulated in the foam insulation, the foam-encapsulating mold forming a first mold half and the fuel tank container forming a second mold half.
Claims6
A method for producing a foam-insulated fuel tank for a motor vehicle, comprising:
- using a heated plastic to blow mold a fuel tank container in a blow molding mold to form a hot fuel tank container;
- placing the hot blow molded fuel tank container in a cooling mold;
- and
- inserting a foam insulation between the cooling mold and an outer surface of the blow molded fuel tank container while the fuel tank container is still hot, thereby causing the foam insulation to fuse together with the outer surface of the plastic of the hot fuel tank container and at least partially encapsulating the fuel tank container with the foam insulation.

A method for producing a foam-insulated fuel tank for a motor vehicle, comprising:
- performing a blow molding step to produce a hot fuel tank container;
- placing the hot blow molded fuel tank container in a cooling mold;
- and
- filling a space between the cooling mold and an outer surface of the hot blow molded fuel tank with a foam insulation so that the foam insulation fuses to the outer surface of the hot blow molded fuel tank and defines a monolithic bond between the foam insulation and the fuel tank container.
