Electronic engraving Anilox Roller is a core component for quantitative ink transfer in flexographic printing and coating field. It is a metal roller with a surface densely covered with specific-shaped micro-holes (ink application holes), used to precisely control the transfer amount of ink or coating liquid.
Working Principlel
The working principle of the l Anilox Roller is based on its precise geometric structure on the surface. It achieves precise ink transfer through the following steps:
*Ink storage: The tiny recessed holes (screen dots) engraved on the surface of the roller body serve as "containers" for storing ink.
*Ink Wiping: Use in conjunction with a doctor blade. The blade should be pressed firmly against the roller surface to scrape off excess ink from the screen walls and the openings of the screen cavities, ensuring that the ink is precisely retained only within the screen cavities.
*Ink transfer: When the anilox roller comes into contact with the plate cylinder or the printing substrate, the ink in the mesh cells is evenly released and transferred under pressure.
Therefore, the amount of ink transferred is determined by the volume of the mesh, which is jointly determined by the shape, depth, and line count of the mesh
Structure and Process
Manufacturing process: Directly engrave (or laser engrave) mesh holes on the metal roller body mechanically, and then electroplate a layer of hard chrome.
application scenarios
Flexographic Printing
It's a primary application, used for printing kinds types of packaging, such as food bags, express delivery cartons, beverage labels, and so on.
Coating & Lamination
Precise application of hot melt adhesives, solvent-based glues, waxes, varnishes, etc., for use in textile lining, pharmaceutical heat-seal packaging, adhesive tapes, etc.
Other Special processes
Like leather matte treatment, embossing, carbon powder coating, etc
