Products Description

The metal wire grid anilox roller, typically made from metal materials (such as steel rollers) with specific wire grid or mesh patterns engraved on its surface, is a core component used in flexographic printing, varnishing, and coating processes to precisely control the transfer of liquids (inks, varnishes, adhesives).

Performance characteristics

*Manufacturing Process and Material: The mesh cavities are typically engraved directly on the steel roller surface, followed by hard chromium plating to enhance hardness (above HRC62) and wear resistance. The material is mostly selected as seamless steel pipe (45#).

*Performance Limitations: The primary constraint is the limited number of engraving lines, typically capped at 400-500 lines per inch. Due to the thin chrome plating layer, wear resistance is relatively poor, especially when equipped with a doctor blade system, leading to rapid wear and shorter lifespan.

*Application scenario: Primarily used in scenarios with relatively low requirements for precision and lifespan, such as partial composite lamination, varnishing, or mid-to-low-end printing, while the high-speed, high-precision flexographic printing field is currently dominated by ceramic anilox rollers.

Mesh Type

Mesh hole shape: According to search results, metal mesh rollers commonly have the following mesh hole shapes, which affect ink release and cleaning difficulty:

Pyramid shape: a common traditional shape.

Hexagonal (honeycomb): considered the most effective geometric shape, with high utilization rate per unit area and uniform ink film, it is a common choice for mainstream mesh rollers (including ceramic rollers).

Diamond shaped, diagonal shaped, etc.: customized according to specific process requirements, for example, diagonal shaped is often used in the coating industry
