Abstract
A coating machine component, e.g., a bell plate for a rotary atomizer, and corresponding production methods are disclosed. An exemplary coating machine component includes a molded base body and a functional element for providing at least one of mechanical stiffening, chemical and/or electrical functionalizing of the coating machine component. The functional element may be made from a material having a greater mass density than the base body. An exemplary functional element may be a coating that is at least partially applied to the base body.

A rotatable bell cup for atomizing paint comprising:
- a base body made of plastic, said base body is a form shaping base body, the base body having a thickness, the base body having a plurality of sides, the plurality of sides including an exterior side having an outer surface and a concave recess, and an inner side in a cavity, wherein the cavity is separated from the concave recess by a wall and a functional element configured to provide mechanical stiffening of to increase rigidity of the bell cup, wherein the functional element is made out of a material with a greater mass density than the base body, and wherein the functional element is a coating, having a thickness, that covers the plurality of sides of the base body, and the base body thickness and the coating thickness are in a ratio of 20:1 to 2:1.
A rotatable bell cup for atomizing paint comprising:
- a base body formed of plastic;
- said base body is a form shaping base body, and a coating on the base body, the coating being formed of metal having a greater mass density than the plastic of the base body and having a greater tensile strength than the plastic of the base body wherein the coating increases the rigidity of the bell cup;
- the base body including a concave recess having a concave surface;
- the base body including an outer surface extending annularly about the concave surface;
- and the base body including a wall extending between and separating the concave recess and a cavity;
- the coating covering the concave surface of the concave recess, and the outer surface of the base body.
