Performance Comparison of Chrome Plating and Chrome Oxide Ceramic Anilox Rolls

       At present, in the field of flexo printing, chrome-plated anilox rollers and chrome-oxide ceramic anilox rollers stand out. The former is economical and the latter is durable. Let's ignore the price difference between the two single rollers and compare them only from the perspective of performance.



1. Hardness



The hardness of the chrome-plated anilox roller with the thickness of the electroplating layer is 0.01-0.15mm is about Hv900, the thickness of the chrome oxide ceramic anilox roller is between 0.1-0.5 (excluding the thickness of the bonding coating), and the hardness is 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.



2. Coaxiality



The coaxiality of the chrome-plated anilox roller is about 0.05mm, and the data of the chrome oxide ceramic anilox roller is not more than 0.03mm. Although the difference is not big from the data point of view, if it is enlarged to a diameter of 50mm and a length of 1700mm On the anilox roller, there is still a big difference in the mechanical runout. Mechanical runout will cause ink flinging or uneven ink layer during the printing process.



3. Engraving accuracy



Mechanically engraved chrome anilox rolls up to 500L/in., laser engraved chrome oxide ceramic anilox rolls up to 1500L/in. A high number of screen lines can form a thinner and more uniform ink film, which can reduce the expansion of ink dots during high-speed printing, and obtain faster drying speed, more accurate overprinting and less ink consumption, ensuring printing quality.
