A molding apparatus includes a first mold part, a second mold part, and an alignment assembly. The two mold parts have an alignment axis and are configured for mating with each other to delimit molding cavity. The two mold parts respectively have a first surface and a second surface, which face each other. The alignment assembly is associated with the two mold parts and includes a light emitting member and a light receiving member. The two members are linked to the two mold parts, respectively. The light emitting member is configured for delivering light to a first location of the first surface at a predetermined position relative the alignment axis. The light receiving member is configured for receiving the light emitted at a second location of the second surface, at a same position relative the alignment axis as the first location.
