Abstract

A system and method for manufacturing and/or molding a plurality of parts, such as a sleeve bearing and a roller bearing, into a predetermined position in the housing wiper motor comprising a component such as a housing. The wiper motor comprises a motor housing, a plurality of bearings integrally insert molded into a predetermined position in the motor housing and a motor situated in the motor housing and having a plurality of shafts which are received in the plurality of bearings. The method for molding a motor housing for use in the vehicle comprises the steps of situating at least one part, such as the sleeve bearing, into a mold for molding the motor housing and then insert molding the housing such that the at least one part becomes integrally formed or molded into a predetermined position therein. In a preferred embodiment, the part is molded into the housing such that it is aligned within a tolerance range of about -0.05 mm to +30 0.05 mm. The housing is then assembled with a motor, and the assembled housing and motor may then be used in a vehicle.
