EMBOSSED ROLL

EMBOSSED ROLL ENGRAVING

In this etching process three-dimensional designs or textures are milled onto the roll’s surface (Etching Press), this product is used for embossing wallpaper, floor and ceiling tiles, leather, vinyl and paper. Each three-dimensional pattern is engraved on a steel core roller, which has a diameter ranging from 20 mm to 600mm.

ANILOX ROLL

ANILOX ROLL ( Surface Process for Hexagon, Pyramid and so on. )

Used for : Coating, Laminating, Bonding (Adhesives) etc.


For both coating and bonding, a variety of mill types are available. Roller mill techniques such as our guadra-gravure, pyramid, hexagonal, or transformed quadra-gravure types may be used. Our rollers are produced in diameters ranging from 20mm up to 500mm, and of lengths up to 4,000mm. A variety of cell shapes may be engraved on steel core rollers or copper plated rollers. The durability of the rollers is insured by the final process of nickel or chrome-nickel plating. Then the rollers are ready for their use in printing, bonding or embossing. Currently, the company is also developing and manufacturing precision rollers.

ANILOX ROLL  ( Surface Process for Hexagonal, Pyramid and so forth. )

All kinds

  • Quadra Gravure
  • The engraved roll has a gravure type trapezoid cell. and the foam has been cut the top of pyramid. compared with same mesh, it foams cell deeper than pyramid type’s and 20 to 50% of ink quantity can be transfered. It is possible to use a doctor blade.
Quadra Gravure
  • Pyramid
  • Because it is an engraved square spindle, it is called the pyramid. Mainly, it is suited for a low supply of ink. The bank width is narrower in comparison to other cells and has a tendency to increase wear. So, it is not suited to the use of a doctor blade.
Pyramid
  • TriHelicoid
  • This V style ditch is engraved on the spiral and is suitable for liquids of a thicker nature with high viscosity like glue, wax and magnetic paint. It is possible to use a doctor blade.
TriHelicoid
  • Hexagonal
  • This cell structure is hexogonal, like the carapace of a tortoise. Compared with tetrahedron cells like pyramid and quadra gravure, the durability when using a doctor blade rises. The heavier nature of the ink is good, and it is optimal for both halftone printing and line printing. This cell structure also prevents moir.
Hexagonal
  • Transform
  • As for cell structure, making bank width on both right and left of Quadra Gravure into rectangle and it is formed the angle of 45 degrees to 60 degrees against total-length. Especially, it is possible for even printing that is able to prevent vertical lines by liquid flow at that time of high speed operation.
Transform

Characteristics

The anilox roll is fundamentally machine engraved. The angle of the cell-wall on the engraved roll is sharp and equalized. This wider bank width results in higher durability. So, cell capacity is obtained precisely with transfered quantity. Engraving is that, embossing is performed by a special prototype-mill which pressure engraves the roll, continuing to form the cell until completion. After that, a hard-chrome process is done to 10~20 μ of thickness.

Function

  • 1. Making 凹 of the cell on metal cylinder endlessly, you can control ink transferred amount with the cell capacity of the part.
  • 2. No vary with high accuracy, even thickness is available in ink-transfers.
  • 3. Even the ink use of high clay is possible.
  • 4. Acting doctor blade, the transfers of even and thin ink membrane is possible. It has an effect in the process printing.
  • 5. Same as gravure cylinder, being processed by copper, nickel and chrome-Plating by machinery method, durability and pair corrosion performance improve substantially.

Attention for Anilox Roll’s operation

An Anilox roll’s life is not permanet. The length of usefullness depends upon the frequency, and method of roll use. The rough-standard, using a 2 roll-method, is a few years or using a steel-doctor blade for 50~1,500,000 meters. There are two methods commonly used to re-engrave rolls. The first is to re-engrave after polishing and the other is to re-engrave after modifying with a copper plating process.


The Anilox roll is already hard-chrome plated. Due to the solutions being utilized, corrosion sometimes occurs with cracking and damage to the chromium layer. But, there is a method to strengthen the roll with a barrier layer of nickel plating.


Please feel free to ask us about other mesh/inch and capacities you hope to use. Also, do not hesitate to ask us about any problems with closed-holes you may have.
