Method for producing metal housings, which are comprised of at least two housing parts, of units mounted in vehicles

Abstract From the Canadian patent

The invention relates to a method for producing metal housings, which are comprised of at least two housing parts, of units mounted in vehicles, particularly in goods-carrying vehicles, by: applying a corrosion prevention layer comprising zinc or a zinc-containing alloy onto an outwardly pointing surface of at least one housing part with a subsequent passivation and; b) , effecting a positive overlapping of an edge of housing part by the edge of housing part by means of a relative movement of the housing parts being reciprocally aligned beforehand with regard to a stamp, which plastically deforms the edge of housing part and/or the edge of the other housing part.
