·Through-Hardened Steel Substrate
Uniform HRC56–62 hardness across the entire roller with balanced toughness and rigidity. Ceramic rollers are brittle and prone to cell chipping and ceramic fragment shedding from foreign debris impact. This roller resists damage from paper fibers, sand, and embedded impurities, offering higher fault tolerance in challenging shop-floor environments.
·No Ceramic Coating Interface
Cells are directly engraved into the hardened steel substrate without sprayed layers. No delamination or peeling risks with long-term exposure to water-based inks and starch adhesives during routine production. The structure remains stable through frequent water washing and mild solvent cleaning.
·Smooth Cell Walls with High Volume
Generous cell volumes in square and diamond patterns release ink smoothly for solid coverage applications. Corrugated board printing achieves rich, opaque colors with strong hiding power—no weak spots or insufficient coverage. Higher printing efficiency compared to conventional rolls.
·G1.0 Dynamic Balancing
Integral forged seamless construction with multi-stage stress-relief processing eliminates internal stress weak zones. Three-stage balancing calibration maintains stable operation under heavy-load pressurization without bending or vibration marks on wide-web coating applications.
·Re-Grinding Restoration
Worn or clogged cells are restored through simple surface grinding and re-engraving without re-coating. Quick repair cycle with lower cost per maintenance event. The affordable initial purchase price combined with low maintenance costs makes this roll ideal for multi-specification, budget-conscious production operations.
