    摘要: A mold 810) for manufacturing a spoke for a non-pneumatic tire is provided that has first and second mold pieces (16, 22) with first and second engagement surfaces to engage the spoke. The first mold piece (16) has a void (20), and is movable relative to the second mold piece. A volume compensation feature (26) is carried by the first mold piece (16) and has a base that is located at the void. The volume compensation feature has a deflection plate (30) that engages the base, and has a non-deflected orientation and a deflected orientation. When the mold is closed the spoke engages the deflection plate and deflects the deflection plate relative to the first engagement surface so as to be in the deflected orientation.
