Shaft Coating Machine

The rod Coater forms a uniform wet film on the substrate surface by rotating a metal rod, used for coating thickness testing of paints and inks. The principle involves grooves engraved on the rod to control the coating amount, and as the substrate moves horizontally beneath the rod, a coating of specified thickness is formed. It is applied in laboratories to simulate coating processes and for quality control.
Selection
When selecting, consider the compatibility of the substrate type and size with the coating width, ensure the coating thickness range corresponds to the rod number specifications, match manual or automatic models to operational needs, verify material corrosion resistance meets sample characteristics, and configure additional functions such as heating or vacuum fixation based on practical application requirements.
