Abstract
A method for producing a control valve assembly using a mold comprising an upper mold half ( ) and a lower mold half ( ). A shaft ( ) with premounted bearing blocks ( ) or other functional components is placed in the mold, and the control valves subsequently are injection-molded on the shaft ( ) in cavities ( ) via feeders ( ) to produce the control valve assembly. Afterward, the bearing blocks ( ) can no longer be detached. Because they are produced separately, the bearing blocks can have a complex geometry. This allows a considerable degree of freedom in the geometric design of the control valve assembly while nevertheless ensuring cost-effective production.
