Abstract
A filter housing, in particular for an air filter for the air intake tract of an internal combustion engine, in which the filter housing (16) includes at least one upper housing section (12) and at least one lower housing section (11) which can be assembled to each other in a sealed manner. The housing sections (11, 12) are produced as centrifugally cast parts and have a geometrically defined outer face (A) and a geometrically defined inner face (I) configured such that the outer face of one of the housing sections (11, 12) can be connected to the inner face of the other housing section, whereby the housing sections can be manufactured in a cost-effective manner and can fit one another snugly.
Claims5
A method for manufacturing a filter housing, said method comprising:
- introducing a plastic powder into a hollow mold corresponding to a housing part to be produced;
- heating the hollow mold to melt the plastic powder;
- rotating the hollow mold about equatorial and polar axes;
- cooling the mold to solidify the plastic, and
- opening the hollow mold and unmolding a unitary housing part comprising a plurality of housing sections integrally connected with each other such that the outside of at least one housing section is connected to the outside or the inside another housing section.
