The simple secondary ejection technology of the ball nut is awarded the utility model patent,With
the popularization of high-end technology of the lamp, it spread to the
low end, the on-vehicle steering technology for the lamp, the use of
the automatic dimming mechanism, in order to meet the large-volume
demand of the ball nut, the Moldfactory Engineering Research and
Development Center developed the ball. The simple secondary
ejection technology of the head nut greatly improves the production
efficiency and shortens the production cycle. This technology was
granted a utility model patent by the State Intellectual Property Office
in December 2013.
