PROEXPORT / INDUSTRIAL ROLLERS
Ceramic Anilox Rollers & Sleeves | PROEXPORT
PROEXPORT ceramic anilox rollers and sleeves are high-precision metering rolls engineered for flexographic printing, varnishing, and gravure coating units. Utilizing plasma-sprayed chromium oxide ceramic coatings engraved with ultra-short pulse fiber laser technology, our anilox rolls guarantee consistent ink film transfer, high line screen resolution, and effortless cleanability.

LINE PROBLEM SOLVING (PWE)
Precision that Eliminates Line Downtime and Web Defects
At PROEXPORT, we do not simply supply coatings — we solve specific engineering challenges for plant technologists and maintenance leaders.
PRODUCTION CHALLENGE
Line Issue
Inconsistent ink density, cell clogging, and premature doctor blade scoring across wide-web flexographic packaging runs.
PROEXPORT SOLUTION
Engineering Solution
Ultra-dense ceramic coating with fiber-laser sculpted cell geometry and micro-polished cell walls that facilitate complete ink evacuation.
PLANT ROI RESULT
Measurable Effect
Predictable, repeatable color density, reduced ink waste, lower doctor blade wear, and faster washdown cycles.
SELECTION & QUALITY CONTROL
Pre-Production Specification & Quality Inspection
Every project — new fabrication or reconditioning — is executed according to strictly defined inspection points:
- 3D interferometric microscope volumetric analysis of cell depth, opening, and BCM.
- Line screen count (LPI/Lcm) and cell angle verification.
- Total indicator reading (TIR) runout and concentricity measurement.
- Ceramic surface micro-hardness and pore sealant verification.
Technical Acceptance Standards
| Inspection Dimension | Technical Significance |
|---|---|
| Geometry & Tolerances | Diameter calibration, radial/axial runout, and concentricity of bearing journals. |
| Coating Structure | Durometer Shore/HV verification, nominal thickness, and zero-porosity bonding. |
| Dynamic Balancing | Residual unbalance compensation in ISO 1940 Grade G 2.5 or G 6.3. |
FREQUENTLY ASKED QUESTIONS (FAQ)
Frequently Asked Questions (FAQ)
How is anilox cell volume (BCM) verified?
We verify and document cell volume using precision 3D white light interferometry and optical microscopes, providing a complete calibration certificate for each roller.
What cleaning protocols are recommended for ceramic anilox rollers?
We recommend regular ultrasonic cleaning or specialized chemical wash solutions. Strong mechanical scraping or aggressive acidic cleaners must be avoided to prevent cell wall damage.
