Method for producing a suction air channel with acoustic channel section

The method involves inserting a porous damping wall segment (3) in a melt of the acoustic channel section during extrusion. A thermal separation is carried out in areas of different temperature between an area (15), in which a porous damping wall segment is guided and another area (16), in which an...

Zusammenfassung:	The method involves inserting a porous damping wall segment (3) in a melt of the acoustic channel section during extrusion. A thermal separation is carried out in areas of different temperature between an area (15), in which a porous damping wall segment is guided and another area (16), in which an air-impermeable wall area of the acoustic channel section is formed.
