Cleaning of Anilox Rolls

Users of the flexographic and gravure printing processes often face difficulties with cleaning their anilox rolls, especially where high-screen counts are present. The delicate nature of these rolls means that printers face concerns over both cleaning efficacy and damage, which can have far-reaching effects on both print quality and profitability.

The good news is that Alphasonics have developed a range of anilox cleaning systems that provide the highest cleaning standards available and will never damage your rolls, even with regular use.

We have designed and currently manufacture five anilox cleaning models, which all provide the very best in advanced ultrasonic cleaning technology. All the features and benefits from these devices can be found on our website.

This technology has been developed over 25 years and it has been our ability to continually produce equipment in-line with screen count rises which put us in such a very strong position. We are the only ultrasonic anilox cleaning equipment manufacturer that offers a written guarantee of roll safety. The reason we can do this is because of the evenness of distribution of sound.

The cavitation graphs below tell the story:-

GRAPH 1

There are both spikes and troughs of sound in the above graph. The spikes show areas of
potential damage to a roll and the troughs indicate areas where cleaning would be poor. The ‘spread’ on the ‘Y’ axis at 17.8mV should also be noted. This graph was taken from a system which was sold into Flexo.

GRAPH 2

Here, with our Advanced Ultrasonic Technology, please note the ‘spread’ at only 1.6mV. The ‘spikes’ can never be completely eliminated, but can be rendered so small that they cease to be an issue. It is this incredibly even distribution that enables rolls to be cleaned on an hourly basis, should the customer desire.

This technology is so effective that it is now also used for the cleaning of surgical instruments within the healthcare de-contamination sector, find out more about our Medstar range here.
