Part weights are always significantly lighter than with metal, even if to keep the same level of part stiffness you always need to increase the plastic part thicknesses, and generously add ribs. Integrating functions is always easier with plastics than with metals, where costly secondary steps are needed for each added function with the latter one. Another advantage with plastics (at least for certain applications) is the...
