Ceramic anilox roller for Offset printing machine
1.Application of Ceramic anilox rollers
Flexo printing machine(unit type, central cylinder type, cascade type)
Gravure printing machine
Corrugated water-based ink printing slotting machine
Coating and lamination machine
Glazing machine ect.
2.Advantage of Ceramic anilox rollers
Uniform cell shape,fast and even ink release
Easy cleaning,ideal cell shape with smooth,steep walls and flat bottom
Precise cell volume
As high a theoretical volume as possible
Longer life expectancy
Good corrosion resistance
High bond strength with base metal
3. Processing Flow of ceramic anilox roller
1. Base roller
A. Material: 45# steel tube or No.5 series aluminum
General performance requirement:45# steel tube
Lighter weight requirement : No5 series aluminum
We can also make the special thickness according to customers requirement.
C. A strict inspection procedure of base roller:
Incoming inspection including surface roughness,straightness, dynamic balance, cylindricity and so on.
2. Chrome oxide ceramic layer
A. Using the famous plasma spraying machine from Switzerland supplier.
B. The evenness of 80% ceramic powder can be controlled between 15u-35u
C. The hardness of chrome oxide ceramics can reach 1200HV.
3. Antiseptic treatment
we use the nanoscopic sealant to coat on the surface of the ceramic which can reach the tiny cell to protect the base roller from solvent corrosion.
4. Precise delivery on the inks
Firstly, we make trial engraving before the real engraving.
Secondly, we use the scanner to scan each layer to test the volume of the cell
Thirdly, according to the relationship between the LPI and BCM, we can make sure whether the LPI is workable.
5. Quality Control
We have the quality control system during the whole production from the very beginning to the end to make sure each roller is qualified.
And we will issue the certification for our customers after the products are finished.
6. Service life
Under nomal operation and maintenance , our ceramic anilox rollers can work 8-10 years or even longer.
