The Fiber Glass Anilox Sleeve is a lightweight, high-performance printing component widely used in flexographic printing. It serves as a direct replacement for conventional heavy metal anilox rolls, designed to be mounted onto an air-mandrel system for rapid sleeve changes, significantly reducing press downtime and improving production efficiency.

Cell Shape

Multi-Layer Composite Structure

The sleeve features a precision-engineered multi-layer construction to ensure dimensional stability, durability, and print quality:

Inner Layer (Fiber Glass Substrate): Manufactured from high-strength fiber glass filament wound around a mandrel, this layer provides the necessary flexibility for pneumatic mounting and demounting. The fiber glass base ensures a snug fit on the air shaft while maintaining structural integrity under press conditions.

Intermediate Layer (Optional Resin/Composite): Some designs incorporate a compressible intermediate layer to enhance cushioning, improve mounting precision, and absorb minor dynamic vibrations.

Outer Layer (Aluminum Base): A machined aluminum alloy shell is applied over the fiber glass core. This layer offers the rigidity and concentricity required for high-speed rotation and serves as the foundation for the ceramic coating.

Working Layer (Ceramic Coating): The outer surface is thermally sprayed with a premium chromium oxide (Cr₂O₃) ceramic coating, which is subsequently laser-engraved with precise cell structures. The ceramic layer achieves a hardness of up to 1300 HV, offering exceptional wear resistance, corrosion resistance, and consistent ink transfer performance.

Main Advantages

Compared to traditional monolithic metal anilox rollers, ceramic anilox sleeves offer significant advantages:

*Lightweight Design

Significantly lighter than steel or solid anilox rolls, enabling faster acceleration/deceleration and reducing bearing wear.

*Quick-Change Capability

Compatible with standard air-mandrel systems, allowing for sleeve replacement within minutes without tools..

*High Print Quality

The laser-engraved ceramic surface ensures accurate and repeatable ink volume delivery, meeting demanding flexo print standards.

*Cost-Effective

Offers a more economical solution compared to carbon fiber sleeves, ideal for general-purpose printing applications.
