Rotogravure Products

The system of Lightweight Air Cylinder and Thin Metallic Sleeve in rotogravure printing represents a significant technological leap if we consider that this printing method mostly continues using heavy steel cylinders and has not migrated to lightweight systems like flexography has done. This is the reason why the latter is so widespread worldwide.

Lightweight Air Cylinder and Thin Sleeve systems reduce the risk of accidents and enhance storage system as it does not require heavy infrastructure to move the cylinders. Sleeves are engraved and stored, and it is not necessary to peel off an engraved image to engrave a new one due to the new image is engraved in a new sleeve. This means that each time an already-printed work order is placed, the sleeve is ready to be used! This advantage places the gravure system in a spot equally competitive than the flexographic system.

COPPER PLATED LIGHTWEIGHT CYLINDER

Ultra-lightweight cylinder for rotogravure printing, with metal shaft, body of epoxy-based composite material and copper plated.

Main Properties:

  • It weighs between 30% and 50% less than a conventional steel cylinder, depending on the size.
  • Body made of epoxy-based composite material.
  • Plated with electrolytic copper 350 microns thick.
  • Steel Shaft.
  • Excelent dimensional stability due to the exclusive alveolar structure that confers the product an optimum balance between strength, stability and low weight.

TECHNICAL SPECIFICATIONS

  • Tolerance: TIR ≤ 0.020mm.
    (Outer Diameter +/- 0.02mm.)
  •  Hardness: 180/190 Hv.
  • Working temperature: 16ºC – 40ºC

POLYMER MANDREL

Lightweight Air Mandrel made of epoxy-based composite material to be mounted with metal sleeves already engraved and ready to be printed.

Main Properties:

  • It weighs between 40% and 70% less than a conventional cylinder.
  • The exclusive alveolar structure confers the product an optimum balance between strength, stability and low weight.
  • Resistance to aggressive solvents. Completely encapsulated, it avoids the absorption of solvents and moisture.
  • Suitable for high speed Printing.

TECHNICAL SPECIFICATIONS

ROTOGRAVURE SLEEVE FOR DIRECT ENGRAVING

Copper sleeve with surface hardness and polishing to be engraved and subsequently chromed

Main Properties:

  • Ultra-lightweight, weighing up to 4kg.
  • Easy storage as it does not require large structures as those used for traditional steel cylinders.
  • Very agile system for design changes, new works and short runs for seasonal promotions, etc.
  • It reduces significantly the logistics and transport costs due to its low weight and easy handling.

TECHNICAL SPECIFICATIONS

  • Material: Electrolytic copper 99.98%.
  • Eccentricity: TIR ≤ 0,015mm

  • Working pressure and flow rate: 6 – 8 bar y 12 liters/sec.

ELASTOMER SLEEVE

Elastomer coated sleeves for lamination processes.
Conical core made of epoxy-based fiberglass, coated with elastomers specifically formulated for application of mono and two-component adhesive

Main Properties:

  • Good resistance to aggressive solvents.
  • Smooth mounting and good fixation on the mandrel
  • High resilience.
  • Ozone resistant.
  • Antistatic properties.
