45 Steel Flexo Anilox Roller Coating Anilox Cylinder for Precision Printing

The 45 Steel Flexo Anilox Roller Coating Anilox Cylinder for Printing is a high-precision printing component engineered for modern flexographic printing machines. Designed with a durable 45# steel core and advanced ceramic coating, this anilox roller provides excellent ink transfer accuracy, long service life, and consistent printing performance.

In flexographic printing systems, the anilox roller acts as a metering device that controls the amount of ink transferred to the printing plate. Laser-engraved microcells on the ceramic surface hold and release ink in controlled volumes, ensuring consistent color density and sharp image reproduction.

With advanced ceramic coating technology, this anilox cylinder provides high wear resistance, corrosion resistance, and stable printing quality even in demanding industrial production environments. Ceramic coatings significantly improve roller durability and allow precise control of the ink film thickness during high-speed printing operations.

The roller core is made from 45# steel or aluminum alloy, ensuring strong mechanical stability while maintaining dimensional accuracy during continuous printing processes.

Durable 45# Steel Core

The roller core is manufactured from high-strength 45# steel, providing excellent rigidity and stability during high-speed printing.

Advantages include:

• strong structural strength
• stable rotation performance
• high resistance to deformation

This ensures reliable performance even under heavy production loads.

Advanced Ceramic Coating Technology

The surface of the anilox roller is coated with chromium oxide or aluminum oxide ceramic, creating a highly wear-resistant surface.

Key benefits:

• high hardness surface
• long service life
• resistance to corrosion and chemicals

Ceramic coatings also improve ink transfer efficiency and maintain consistent printing quality.

Precision Laser-Engraved Cell Structure

The roller surface contains millions of precisely engraved microcells.

These cells function as ink reservoirs that meter ink accurately during each rotation.

Available cell shapes include:

• hexagonal cells
• trihelical cells
• ART cells

These engraving options allow the roller to adapt to different printing applications and ink types.

Wide Line Screen Range

The anilox roller supports line screens from 30 to 2000 LPI, enabling flexible printing resolution based on customer requirements.

Lower LPI values are typically used for heavy ink transfer, while higher LPI values are suitable for high-resolution printing.

The 45 Steel Flexo Anilox Roller is widely used in various industrial printing applications:

Label Printing
