HDA high speed electrostatic rotating spray bell for gears nuts auto coating , the Coating conductivity  Dacromet coating has high resistance and is not suitable for bolts that require conductive connections (such as grounding components)
Color restriction: only silver white/gray, adhesion needs to be evaluated when post-processing color change is required

This technology can further improve efficiency through automated spraying (such as intelligent robots) and is suitable for bolts in fields such as construction machinery and automobiles.
