Gravure Coating Steel Embossing Roller Chrome Plated HRC 62 Mirror Finish Solvent Free Cleaning
The gravure coating steel embossing roller is designed for gravure coating, laminate coating, flexography and gravure printing applications. Gravure pattern, mesh and depth are selected according to coating material, coating amount, base substrate and feed speed. The roller body is produced from 45# seamless steel pipe or alloy steel after welding, stress relieving, tempering, quenching and precision grinding.
A hard chrome plated surface reaches HRC 62 with a mirror finish, offering excellent chemical resistance and allowing solvent-free roller cleaning. With surface roughness at Ra 0.01 and concentricity below 0.02 mm, this roller provides consistent coating transfer, uniform film thickness and long, reliable service in high-speed production environments.
Key Features- Gravure Coating Roller: Optimized gravure cell, mesh and depth for precise coating transfer and uniform film thickness.
- Chrome Plated Mirror Finish: Hard chrome plating to HRC 62 with a mirror finish for chemical resistance and easy release.
- Solvent Free Cleaning: Smooth chrome surface permits solvent-free cleaning, reducing cost and environmental impact.
- 45# Seamless Steel Pipe: Welded, stress relieved, tempered and quenched base for structural stability and low runout.
- Ra 0.01 Surface Roughness: Mirror polishing ensures smooth rotation and consistent coating application.
- Concentricity Below 0.02 mm: Precision grinding keeps runout minimal for uniform web contact and coating quality.
