High-Level Anilox Performance

There are two styles of anilox base sleeves on the market today. The majority of sleeves employ a core expansion style, while the remainder use a solid build-up style. Both have a composite core sleeve with a wall thickness of approximately 0.040 inches. The core expansion style relies on a polyurethane foam expansion layer that compresses as the core expands when the mandrel air supply is applied. There is a secondary composite build-up layer applied to the foam expansion layer that allows the aluminum tube to be pressed and glued in place without compressing the foam, as that would render the sleeve too tight.
