1. A method of manufacturing a component having a main body and at least one ring sleeve through a molding assembly, the method comprising:
providing a mold having an inlet and defining a hollow portion;
placing at least one core to form a free-space within the component inside the mold to bifurcate the hollow portion into a first cavity and a second cavity;
pouring a molding material inside the mold through the inlet;
allowing the molding material to set inside the mold around the core within the first cavity and the second cavity to form a main body and at least one ring sleeve of the component;
connecting the first cavity and the second cavity and forming at least one first bond and one second bond between the main body and the at least one ring sleeve;
removing the at least one core from at least part of the hollow portion within the mold; and
providing the core with at least one recess allowing the molding material to flow therethrough such that on withdrawing the core out of the mold, at least one first bond breaks and on withdrawing the core outside the mold, at least one second bond breaks.
