Method for welding a heat shield during manufacturing of a vehicle component

A method for welding a heat shield during manufacturing of a vehicle tank, or a filler pipe, the tank or the pipe being made from a thermoplastic material, the heat shield including:

• a reinforcement layer made from a thermoplastic material which is weldable to the thermoplastic material of the vehicle tank or filler pipe;
• and a heat shielding material which differs from the thermoplastic material of the reinforcement layer and which is configured to decrease transfer of heat through the reinforcement layer to the vehicle tank or filler pipe;
• the method comprising:
• 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 tank or filler pipe in a molten state;
• welding the thermoplastic material of the reinforcement layer being in a molten state to the thermoplastic material of the vehicle tank or filler pipe being in a molten state, by blow molding the vehicle tank or filler pipe in the mold.
