Abstract: A method for manufacturing a thermoplastic component for fuel systems or SCR systems includes the following steps: (1) molding and/or forming of a thermoplastic substrate from a first thermoplastic material, and (2) three-dimensional printing of a second thermoplastic material onto a first area of the thermoplastic substrate obtained after step (1). The first thermoplastic material of the thermoplastic substrate and the second thermoplastic material have a chemical compatibility.

Abstract: An internal casing for a pressurized fluid storage tank for a motor vehicle includes: a hollow body includes a layer made of a first polymer material; and a neck arranged on the hollow body and delimiting an opening of the hollow body, the neck receiving an interface part mounted on the neck in a sealed manner by a gasket arranged between the neck and the interface part. The neck is made of a composite material composed of a second polymer material loaded with reinforcing fibers, the composite material having a deformation resistance than that of the first polymer material. The neck is joined to the hollow body by molecular entanglement of polymer chains of the first polymer material and polymer chains of the second polymer material. Methods for manufacturing such an internal casing, and a storage tank including such an internal casing are disclosed.

Abstract: A method for welding a heat shield during manufacturing of a vehicle component made from a thermoplastic material. The heat shield includes: a reinforcement layer made from a thermoplastic material which is weldable to the thermoplastic material of the vehicle component; and a heat shielding material that differs from the thermoplastic material of the reinforcement layer and is configured to decrease transfer of heat through the reinforcement layer to the vehicle component. The method includes: heating the heat shield to bring the thermoplastic material of the reinforcement layer in a molten state; placing the heated heat shield in a mold; bringing into the mold the thermoplastic material of the vehicle component in a molten state; welding the thermoplastic material of the reinforcement layer being in a molten state to the thermoplastic material of the vehicle component being in a molten state, by blow molding the vehicle component in the mold.
