Examples of Spray Process Improvements

Some examples of process developments and improvements that have been achieved using ultrasonic spray technology and prototyping services offered by our Sono-Tek laboratory:

  • Increased throughput and minimized excess misting while providing uniform coverage over a wide area in a float glass spray application resulting in a 75% reduction in material usage.
  • Designed a nozzle to meet precise drop size requirements in spraying of microparticulates in medical applications, such as drug delivery.
  • Developed a highly effective process for spraying of nanoparticle solutions with significantly less agglomeration than conventional methods.
  • Developed a process for applying flame-retardant solutions to fabrics.
  • Optimized thin film coatings from 5μ down to .1μ and increased uniformity from ±10% down to ±2%.
  • Optimized coating morphologies from a grainy structure to continuous smooth films.
  • Reduced consumption of expensive drug/polymer solution being sprayed by 80% – saving the customer $14,000 per month with a 2 month ROI.

Some of the projects that can be performed in our Sono-Tek laboratory include:

  • Prototyping and customizing nozzles to specific applications
  • Customizing frequency and drop size based on liquid vapor pressure and surface tension
  • Spray characterization studies with different nozzles under different operating conditions
  • Testing spray performance using actual parameters
  • Adjusting spray parameters to increase efficiency and improve results
  • Improving process and reducing reject rate
  • Troubleshooting process problems resulting from unsatisfactory spray quality
