Anilox cleaning machine

Anilox rolls are essential components in flexographic and offset printing, as they control the transfer of ink to the printing plate. Proper maintenance is crucial to ensuring consistent print quality and prolonging their lifespan. Over time, anilox rolls accumulate ink residue, varnish, and other contaminants that can clog their cells and reduce ink transfer efficiency.

In this regard, ultrasonic cleaning has proven to be one of the most effective methods for deep residue removal without damaging the roll structure. Discover with DCM Ultrasonic how this process works, its benefits, and best practices for ultrasonic anilox roll cleaning with our Anilox cleaning machines
 

The Importance of Anilox Roll Cleaning

Anilox rolls are designed with thousands of microcells that retain ink and transfer it to the printing plate. Without proper cleaning, these cells can clog, affecting print quality by creating inconsistencies in ink distribution. Some of the most common problems associated with poor cleaning include:

• Loss of transferability: Ink does not deposit evenly, affecting print definition.
• Premature roll wear: Accumulated residue can create additional friction and affect the roll surface.
• Reduced productivity: The need for constant adjustments due to ink transfer issues can slow production and increase material waste.

To avoid these issues, an efficient and safe cleaning process for anilox rolls is essential.

Anilox cleaning machine - With ultrasonic cleaning

Ultrasonic cleaning is an advanced process that uses high-frequency sound waves to remove dirt and residue from anilox rolls. This method is based on cavitation, a phenomenon in which tiny bubbles are generated and collapse in a cleaning fluid. When these bubbles implode, they generate micro-explosions that dislodge contaminants from the roll's surface without causing damage.

The ultrasonic cleaning process consists of the following steps:

1. Roll preparation: The anilox roll is disassembled and inspected to determine the level of dirt.
2. Cleaning tank immersion: The roll is immersed in a specialized cleaning solution inside an ultrasonic tank.
3. Ultrasonic activation: Ultrasonic waves are generated that create cavitation bubbles, removing ink and varnish residue from the roll's microcells.
4. Rinsing and Drying: Once the process is complete, the roller is rinsed with demineralized water and dried with compressed air to prevent corrosion.
5. Final Inspection: The roller is verified to be completely clean before being reinstalled in the printing press.

 

Benefits of Ultrasonic Anilox cleaning machine

1. Deep and Uniform Cleaning
The main benefit of ultrasonic cleaning is its ability to remove residue from all roller cells, including those that are difficult to access with other cleaning methods.

2. Does Not Damage the Roller Structure
Unlike mechanical methods, ultrasonic cleaning does not cause wear on the roller surface, which extends its lifespan and reduces the need for frequent replacements.

3. Greater Efficiency and Cost Reduction
This automated method allows for fast and efficient cleaning, reducing downtime and optimizing operating costs by minimizing the use of harsh chemicals.

4. Eco-friendly and safe process
Ultrasonic cleaning reduces the use of chemical solvents and generates less waste, making it a more sustainable and environmentally friendly option.

Anilox cleaning machine - Our Series

At DCM Ultrasonic, you can find different types of ultrasonic cleaning equipment designed for anilox rolls, including:

• SL SERIE: The machines in this range are designed for rolls of different sizes and offer efficient cleaning in a single cycle. Furthermore, if the roll has high levels of dirt and contamination, the DL Range is recommended due to its dynamic loading system.
• RL SERIE: The machines in this range allow for homogeneous cleaning by rotating the roll during the cavitation process.
• Integrated Cleaning Systems: Designed for high-volume production lines, they automate the process and optimize efficiency.
