  • Known intake manifolds such as the intake manifold duct of a switching intake manifold according to DE-A 195 04 256, are made from polyamides. Intake manifolds are also generally known made of cast metal. Intake manifolds are generally sanded on metals or made of plastic, each based on the principle of the lost core. These parts and the manufacturing processes have disadvantages.
  • the sand casting leads to components heavily varying wall thickness, e.g. with thickness limits of 2.5 - 4.5 mm. Therefore point Castings also weigh heavily and the surfaces are rough. Rough inner surfaces affect the flow behavior of the passed fluid, rough exterior Surfaces impair the appearance and the feel of the parts.

Further One possibility is to connect the shoulder surfaces touching one another Combination of gluing and welding, for example spot welding, or a combination of gluing and riveting and clinching, like riveting, or that Folding and gluing to form a seam seam.
  • the weld seam can be produced by arc welding under protective gas, such as TIG welding or MIG welding, by plasma welding, electron beam welding, laser welding, such as using ruby, YAG, neodymium or CO 2 lasers, friction welding, etc.
  • Laser or friction welding seams are preferably arranged between the shell-shaped parts.
  • the adhesive seam can be produced by an adhesive.

Adhesives that form thermosetting or at most elastic connections are preferable.
  • the intake manifold surfaces can be glossy, matt or embossed. Functional or decorative shapes can also be formed in the bowl-shaped parts attach. In addition to their functional shape, the intake manifold can also be in optically appealing form and / or further developed with lettering, logos or patterns become.
