The aluminum alloy ceramic anilox roller is a high-performance ink transfer roller made of high-strength aluminum alloy as the base material, with a ceramic layer plasma sprayed on the surface and precision laser engraving technology applied. It is mainly used in flexographic printing, coating, and glazing equipment, and is currently the core component in the printing industry for achieving high-precision and high-consistency ink volume control..
Why choose Aluminum Alloy pipe as the base material
High-strength aluminum alloy (such as 5-series or 6-series aluminum) is selected. Compared to traditional steel rollers, it is lighter in weight, facilitating easier operation and high-speed rotation.
Making Process

Product Superiority
The density of the aluminum alloy matrix is about 1/3 of that of steel, resulting in low inertia. It consumes less energy during startup and shutdown, making it particularly suitable for high-speed rotating equipment and reducing the overall load on the equipment.
The ceramic coating boasts an extremely high hardness (such as alumina, which can reach HV1000 or higher), and its wear resistance is several times of chrome-plated steel rollers. This effectively prevents scratches and maintains surface precision over the long term.
Ceramic materials can withstand high temperatures of several hundred degrees (such as alumina ceramic rollers that can operate stably at temperatures above 1000°C), and have a low coefficient of thermal expansion, making them less prone to deformation during temperature changes.
Ceramics exhibit stable chemical properties and are resistant to corrosion by acids, alkalis, and organic solvents, unlike metal rollers which are prone to rusting. This characteristic makes them an ideal choice for use in corrosive environments such as the chemical industry, PCB cleaning, and marine engineering.
After precision grinding, the surface of the ceramic roller exhibits an extremely high degree of smoothness (reaching mirror-like quality) and a low friction coefficient. This ensures product quality (such as scratch-free films and paper), while also significantly extending the cleaning cycle of the equipment.
