The film thickness can be maintained by scraper and support roller, and smooth coating and mounting can be carried out at high speed. Care should be taken to avoid stripes (linear defects).

By supplying coating liquid from the liquid chamber, the release of solvent odor and viscosity change can be reduced, and the replacement of scraper is more convenient. Used for direct engraving wheel, reverse engraving wheel, etc.

After coating, apply the mounting surface evenly through the straight rod. It is suitable for micro high-speed coating and mounting of bottom and top coatings.

Suitable for water-based coating and mounting liquid. After coating, apply the mounting surface evenly by air (air pressure). The utility model has the advantages that it is not easy to be affected by the thickness of the substrate and the concave convex surface.

In addition to the above methods, for various conditions, in order to carry out high-precision / high-speed smooth coating and pattern mounting, various coating methods and combinations are also used. The following will list the application of some coatings and the development trend of coating equipment.
