Product Overview: Precision Meets Efficiency

The combination of the C797 air cap and the 0.7 mm nozzle (Order No. 2180513) is specifically designed for the fine, directed application required for marking work. This configuration ensures exact material dispensing.

Recommended Basic Settings (Guidelines)

For optimal results with low-viscosity Colad marking products, the following values serve as a starting point. Note that actual settings depend on the material's viscosity, ambient temperature, and the desired mark width.

     
• Atomization Air Pressure (Guideline): 1.5 - 2.5 bar
     
• Fluid Pressure (Guideline): 0.5 - 1.0 bar (depending on material feed and viscosity)
     
• Spray Distance (Guideline): 150 - 250 mm
     
• Nozzle Size: 0.7 mm
   

Ensure the Colad marking material is precisely adjusted to the recommended viscosity for the 0.7 mm nozzle. Viscosity that is too high leads to a poor spray pattern, while viscosity that is too low can cause runs and sags. Use a viscosity cup for measurement.

Pro Workflow for Consistent Marking Quality

     
1. Preparation: Check all seals and ensure the gun is clean. Mix and filter the Colad material.
     
2. Test Run: Perform a short test on a sample piece to check the spray pattern and verify the recommended basic settings.
     
3. Fine-Tuning Spray Pressure: Adjust the atomization air pressure until a uniform, fine spray pattern is achieved, without creating excessive overspray.
     
4. Stroke Adjustment: Set the needle stroke so that the material quantity of the 0.7 mm nozzle is optimal and the desired film thickness is achieved.
     
5. Automatic Operation: Run the spray cycles automatically. Constantly monitor the material flow and the marking result.
     
6. Cleaning: Immediately after finishing the work, thoroughly flush the gun with a suitable cleaner to prevent nozzle blockages.
   

Common Issues and Troubleshooting

     
•         Issue: Uneven Spray Pattern / Droplets        
           
  • Action 1: Check viscosity – dilute material if necessary.
           
  • Action 2: Check nozzle and air cap for blockages and clean them.
         
       
     
•         Issue: Spray Fan is Too Wide        
           
  • Action 1: Slightly reduce atomization air pressure.
           
  • Action 2: Check that the C797 air cap is correctly mounted.
         
       
     
•         Issue: Material Flow is Non-Existent or Irregular        
           
  • Action 1: Increase fluid pressure (observe guideline).
           
  • Action 2: Adjust or replace the needle packing or needle stroke.
         
       
   

Maintenance for Longevity

     
• Daily cleaning of the nozzle, needle, and air cap with the appropriate solvent.
     
• Checking the fluid and air valve seals for wear.
     
• Regular greasing of moving parts (e.g., needle assembly), according to manufacturer specifications.
     
• Replacement of nozzle sets and needles when visible wear occurs or the spray pattern becomes uneven.
     
• Only use soft brushes to clean the air cap to avoid damaging the precision bores.
   

FAQ for Binks C797-07 in Marking

A: It is ideal for low-viscosity marking paints. For highly viscous or heavily pigmented materials, you should precisely check the viscosity or consider a larger nozzle set to prevent blockages.

A: ROC stands for a special atomization technology that aims for optimized, fine atomization at lower air pressure, which minimizes overspray and saves material – ideal for high-precision markings.

A: Yes, the AGMDP/ROC is versatile. However, for thicker or more abrasive materials, the nozzle set and air cap would need to be adjusted.

A: With regular, correct cleaning and the use of non-abrasive Colad materials, nozzle sets last a long time. Highly viscous or heavily abrasive fillers will shorten the lifespan.

A: The AGMDP/ROC is designed as an automatic gun and features standard connections that allow for straightforward integration into most automated coating systems and robotic cells.
