Abstract

A method for casting a ring-shaped plastic frame comprises providing two mold parts, wherein at least one of the two molds parts includes at least one ring-shaped seat. Positioning a rotor disk between the two mold parts where the rotor disk comprises at least one annular recess. Engaging a mold core with at least a portion of each of the two mold parts. The mold core comprises at least one casting channel configured to attach at one end to a supply of plastified plastic. Inserting at least one mold insert into the at least one ring-shaped seat. A mold volume is defined by the at least one mold insert, the mold core and an edge of the at least one annular recess, wherein the mold volume is configured to fluidly connect with the at least one casting channel to receive plastified plastic to form a plastic frame.
