In the current flexo printing field, chrome anilox rollers are gradually replaced by ceramic anilox rollers. The former is economical and the latter is durable. In this article, we do not consider the price factor, but only compare from the performance point of view.
The coating thickness of chrome-plated anilox roller is generally between 0.01 and 0.15, and the hardness is about Hv900. the coating thickness of the ceramic anilox roller is between 0.1-0.5 (excluding the thickness of the bonding coating)，Its hardness reaches Hv1300-1400，the difference in hardness reveals that the anilox roller with higher hardness has more advantages in wear resistance.After data collection, the service life of the latter is 4-5 times longer than that of the former.
The coaxiality of the chrome anilox roller is about 0.05mm, and the data of the ceramic anilox roller is not more than 0.03mm. although from the data point of view, the difference is not big, but if it is enlarged on the anilox roller with a diameter of 50 mm and a length of 1700 mm, there is still a big difference in mechanical runout. mechanical beating will cause ink throwing or uneven ink layer during printing.
Mechanically engraved chrome anilox roll up to 500L/in, Laser engraved ceramic anilox roll up to 1500L/in. high screen ruling can form a thinner and more uniform ink film, reduce the expansion of ink dots during high-speed printing, and obtain faster drying speed, more accurate overprinting and less ink consumption to ensure printing quality.
The above is the main performance comparison between chrome-plated anilox roll and ceramic anilox roll.
