    why plastic for this piece?

    why is the black piece plastic instead of just extending the metal? its bolted down. is it just for the axel support? Can you think of a reason they did this?







    thanks for your opion

    Looks like a ball thrower... Since the plastic/metal part is meant to rotate on completion of the throw is is likely meant to absorb some impact loading as well.

    I suspect that the kinematics of the mechanism needs a softer material at that linkage..
    Tell me and I forget. Teach me and I remember. Involve me and I learn.

    Or maybe the geometry of all the features was easier to obtain with a molded part rather than multiple separate machining and/or welding operations with metal.
