1. A method for producing a moulded body closed by a cavity by welding two components (1a, 1b),

the method comprises steps a), b), c), d) and e):

a) providing a first component (1a), wherein the first component (1a) comprises a continuous welding web (2a),

b) providing a mould (5) comprising a continuous channel (7a), wherein the trajectory of the channel (7a) substantially corresponds to the trajectory of the welding web (2a), wherein the channel (7a) comprises means (11a) for introducing hot gas, and wherein the mould (5) comprises means (30a) for actively adjusting the pressure,

c) positioning the welding web (2a) of the first component (1a) in the region of the channel (7a) of the mould (5), thereby forming a first interior space (20a) between the first component (1a) and the mould (5),

d) introducing hot gas through the channel (7a) so that the welding web (2a) of the first component (1a) melts and the pressure in the first interior space (20a) is actively regulated by means (30a), and

e) bringing the molten welding web (2a) of the first component into contact with the welding web (2b) of the second component (1b), wherein the trajectory of the welding web (2b) substantially corresponds to the trajectory of the welding web (2 a).

2. The method according to claim 1, wherein the device (30a) is located in an area enclosed by a trajectory of the channel (7 a).

3. The method according to claim 1 or 2, wherein step a) further comprises providing a second component (1b), wherein the second component (1b) comprises a continuous welding web (2 b).

4. The method according to any one of claims 1 to 3, wherein the mould (5) provided in step b) comprises a first side (6a) and a second side (6b), wherein the channels (7a) are arranged on the first side (6a), and wherein the continuous channels (7b) are arranged on the second side (6b), wherein the channels (7b) comprise means (11b) for introducing hot gas, and wherein means (30b) for actively adjusting the pressure are arranged on the second side (6 b).

5.

6. The method according to any one of claims 1 to 5, wherein gas is evacuated from the first interior space (20a) and/or the second interior space (20b) by means of a device (30a) and/or a device (30 b).

7. The method according to any one of claims 1 to 5, wherein the gas is introduced into the first interior space (20a) and/or the second interior space (20b) by means of a device (30a) and/or a device (30 b).

8. The method according to any one of claims 1 to 7, wherein in step c) the solder web (2a) is located in the region of the channel (7a), wherein the distance (Xa) between the end face of the solder web (2a) facing the die (5) and the channel entrance plane (14a) is >0 to 3mm outside the channel (7a) or 0 to 10mm inside the channel (7 a).

9. The method according to any one of claims 1 to 8, wherein in step c) the welding web (2b) is located in the region of the channel (7b), wherein the distance (Xb) between the end face of the welding web (2b) facing the die (5) and the channel entrance plane (14b) is >0 to 3mm outside the channel (7b) or 0 to 10mm inside the channel (7 b).

10. Moulded body enclosing a cavity, obtainable by a method according to any one of claims 1 to 9.
