Cleaning of air-conducting components for internal combustion engines

Application: Manufacturing components for the automotive industry

Initial situation

Engine components, e.g. parts for the intake manifold and cylinder head cover, are manufactured in an injection moulding process. Further production steps include inserts being pressed in and individual parts being welded together (laser welding, vibration welding, US welding).

Electrostatic charging attracts loose particles from the environment, and metallic and non-metallic particles from the manufacturing steps accumulate on the surface and in cavities of the components. These particulate contaminants should be reduced as much as possible in a final cleaning step before the assemblies are packaged.

Solution

A separate cleaning station is set up for the final cleaning of parts. The machine is loaded and unloaded manually.

There are various part holders for the different components, depending on the type (for one or two parts). Cleaning is carried out with a special cleaning head, that has been specifically designed for the components. The internal passages of the intake manifolds are adapted and cleaned separately. A shutter seals off the cleaning area to reduce noise levels. After a successful cleaning process, the part can be marked with a stamp, removed and packaged. The system features an integrated suction system with filter.
