In the decorative paper impregnation process, secondary coating demands exceptional precision. Conventional screen rollers frequently encounter two major issues: thin screen walls that are prone to scratching, resulting in uneven coating and frequent production stoppages.
Today, HERZPACK has introduced a high-capacity, highly durable direct-embossed coated mesh roller specifically designed for decorative paper impregnation machines, effectively addressing operational challenges in equipment operation.
Core Performance Overview:
- Extravagant coating capacity: The mesh cable achieves a capacity of 10 LPC with a mesh cell volume up to 120 CC, perfectly meeting the requirements for high coating volumes in secondary coating applications.
- Direct carving technique with ultra-thick mesh walls: breaking away from traditional carving methods.
Conventional embossed mesh walls are extremely thin (indicated by the red arrow) and highly susceptible to wear. Our HERZPACK employs direct embossing technology to produce thicker, more durable mesh walls, completely eliminating the issue of scratch damage to the mesh cells and significantly extending their service life. - High-speed operation ensures smoother scraping performance: The top surface of the grid wall in the direct engraving process features a ceramic layer that has been originally ground and polished, resulting in an exceptionally smooth surface. During high-speed operation, the scraper adheres more smoothly, significantly reducing friction noise while substantially extending its service life.

Recommendation: Given the deep cavity (120 CC), using a ceramic spatula is recommended to further reduce wear and ensure consistent coating coverage.
