GRAVURE CUP ROLLERS

Gravure cup rollers are used for gravure coating, laminate coating, flexography and gravure printing. Gravure pattern, mesh and depth are selected depending on coating materials and amount, base materials and feed speed. In addition, roller cleaning without solvent is available.

MILL ENGRAVING

This is a method to transfer the patterns by fitting a mini roller, called a Mill, into the gravure cup roller.

  • PYRAMID TYPE CUP
    Pyramid type cup is suitable for the small amounts coloring and coating. It is used for transfer without doctor blade often.
    PYRAMID TYPE CUP
  • TRAPEZOIDAL TYPE CUP
    Trapezoidal type cup has much transferability than Pyramid type cup. It is used for transfer with doctor blade often.
    TRAPEZOIDAL TYPE CUP
  • HEXAGONAL TYPE CUP
    Hexagonal type cup has much transferability than Trapezoidal type cup cause larger space and angle. It is suitable for heavy materials like adhesive.
    HEXAGONAL TYPE CUP
  • VIRGULE TYPE CUP
    Virgule type cup is suitable for viscosity materials such as amounts of colorant, adhesive, and magnetic material.
    VIRGULE TYPE CUP

ETCHING ENGRAVING

This is a method to engrave patterns by masking the surface of the roller and eroding arbitrary patterns.

  • The optional pattern cups are available.
  • Precision adjust the amounts of coating on width direct is
    available by gradation.
  • There is no difference in level between engraved parts and
    non-engraved parts.
  • No consistent engraving, engraving in uniform.
  • Partial painting and intermittent painting are available.
  • Non-physical impact engraving brings accurate roller
    manufacturing.
  • The minute patterns are available.

LASER ENGRAVING (CERAMIC GRAVURE ROLLER)

This is a method to engrave patterns directly with a laser after spraying ceramic on the surface of the roller.

Hexagonal 600Mesh、15um

Hexagonal 1000Mesh、5um

  • Spraying superior abrasion-resistant, corrosion-resistant ceramic (chromium oxide)
  • Engraving fine patterns, which exceed 1000 Mesh in size.

EXAMPLES OF GRAVURE CUP ROLLER USE

  • DIRECT GRAVURE COATING
  • OFFSET GRAVURE COATING
  • REVERSE GRAVURE COATING

GRAVURE UNIT TEST

GRAVURE UNIT TEST
  • We arrange a simple gravure unit to compare patterns, which are produced on the materials, each of pattern specifications, engraving method, and surface finishing.
  • We manufacture gravure rollers with any pattern specification to meet your requirements.
  • This unit can be attached to our testing machine GPD350D.
Roller size D60xW280mm
Coating method Direct, reverse
GPD350D's dryer is available.

ROLLER CLEANING

Mix compressed air, water, and media (powder), and spray it on rollers to clean them.
No solvent is used at all.
