OPC coating

OPC processing


This is a dip coating machine for organic photoreceptor drums, which are the main components in copiers and laser printers.
It is able to minimize speed fluctuations and bubble formation.
Beginning with the coating portion which suppresses equipment vibrations to within microns, the line comprises various portions incorporating expertise for explosion-prevention, cleaning, and other functions. This stabilizes the coating film to achieve a high-precision coating with an accuracy of within 5 μm.
