Method for producing a plastic housing comprising an incorporated guide and/or bearing for mechanical components

Method for producing a plastic housing for a brake lining comprising:

• providing a brake lining wear sensor configured for measuring a displacement of a brake lining relative to an associated brake caliper caused by wear, whereby a linear displacement is converted into a rotational movement by means of a planetary gear unit and the brake lining wear sensor measures the resulting rotational movement;
• molding at least one first plastic housing part with a disc shaped configuration and a functional geometry into a disc shaped external surface, the functional geometry being shaped as a plurality of bearing pins configured for rotatable bearing of gear wheels of he planetary gear unit, wherein a plurality of gear wheels are mechanically moving components of the brake lining wear sensor;
• entirely or partially overmolding the at least one first plastic housing part while a second plastic housing part is being formed;
• and
• forming an integral plastic housing via said molding and overmolding, wherein the integral plastic housing is hood-shaped and the plurality of bearing pins project into the internal space of the hood-shaped integral plastic housing.
