Introduction to sleeve anilox rollers
Imported chromium oxide ceramic powder (Cr₂O₃) forms the engraving layer. Direct engraving with an ALE laser system precisely controls screen ruling and cell volume (LPI/BCM, LPC/cm³/m²). Different laser types, powers and wavelengths are available to meet customer requirements for ruling and volume.
Beyond standard cell geometries such as hexagonal and UV patterns, customized cell shapes and engraving parameters can be developed for new products and processes. All sleeve bases currently use imported materials.
Compatible equipment brands include W&H, BOBST, Gallus, Comexi, Aerospace Huayang, Weifang Donghang, Qingzhou Yigaofa and Ruian Changhong.
Sleeve anilox rollerFeatures
Long service life: hardness above 1250 HV and printing durability exceeding 5 million meters.
Consistent surface: direct fiber laser engraving minimizes cell volume variation across the roller for uniform printing.
Repeatable batches: digitally controlled engraving ensures consistency between repeat orders.
High transfer rate: low porosity and surface characteristics help ink transfer to the plate.
Improved print precision: engraving up to 1500 LPI meets high-definition flexographic printing requirements.
Technical advantages of sleeve anilox rollers
Improved sleeve base production uses heated interference fitting, adhesive bonding and bolt fixing to make the base stronger and safer.
Materials in the sleeve base layers have been optimized.
Sleeve bases can be refurbished 3–5 times while maintaining precision.
Sleeve anilox rollerLead time advantage
Roller bases are manufactured in-house. A new sleeve anilox roller can be completed in as little as 15 days, with a typical production cycle of 20 days.
