Abstract
A method for manufacturing a ball joint ( ) consisting of a ball-ended spindle ( ) and a socket ( ), having no bearing shell and being already assembled during the manufacture includes, placing the ball-ended spindle ( ), which comprises a ball ( ) without a flattened pole surface, into an injection molding tool ( ). The ball-ended spindle ( ) is retained by a core puller ( ) that seals a hollow space of the injection molding tool ( ) relative to the ball ( ) and simultaneously forms a clearance ( ) for realizing a maximum pivoting angle of the ball-ended spindle ( ) relative to the socket ( ), whereafter the ball ( ) is directly coated with plastic by means of injection molding so as to form the socket ( ).
