FinnSonic - Aerospace Ultrasonic Cleaning Solutions and FPI Systems

FinnSonic, headquartered in Finland, has served customers worldwide for over 40 year, offering intelligent, safe, and cost-effective solutions for demanding parts cleaning needs. 

General benefits of FinnSonic solutions for industrial parts cleaning and NDT inspection

  • Top quality at lower cost
  • Short cycle times
  • Removes particles down to micron grade
  • Cleans even the toughest impurities from complex structures
  • Works with a wide range of different chemicals
  • Environment-friendly

Ultrasonic Cleaning Cavitation Technology 

When a component is immersed into the ultrasonic tank, an ultrasonic frequency vibration is transmitted into the liquid creating cavitation bubbles; and those cavitation bubbles are the ones that remove the impurities from the part surface. 

Intelligent solutions to detect surface cracks on aerospace components. Non-Destructive Test (NDT)

10 Key reasons to choose FinnSonic FPI lines for the aerospace industry

  • Save time: the high capacity of the line conveyors processes several parts at a time using baskets or individually specially designed.
  • Efficient use of labor time: the line automation transports the parts through each treatment phase giving the operator the freedom to perform other tasks.
  • Optimize space: in addition to the line’s high capacity, FinnSonic delivers the smaller possible size.
  • Monitors: the line system monitors different variables such as jet pressure, treatment temperatures, and treatment times, minimizing human errors.
  • Traceable: the system line, automatically, records the data giving the operator the ability to review and check the values of the variables.
  • Repeatability: improving facility operational efficiency.
  • Smart process for smart results: the electrostatic penetrant liquid and developer spray process guarantees an even result and reduce the chemical consumption.
  • Enhance workplace safety: the safety casing reduces the noise level and prevents vapors from contaminating the workplace environment. (As an option, a vapor extractor system can be added.)
  • Optional cleaning: an ultrasonic cleaning integration is possible.
  • Environmentally friendly: the line is designed for efficient energy and water consumption.

Clean aircraft oil and fuel pumps in 15 min

most relaible solution to clean aircraft oil pump housings

 It is well known that cleaning a component with internal cavities and small holes is a challenge, and a time-consuming process. However, the right equipment brings the possibility to clean the aircraft components in a better and faster way.

A small and automated FinnSonic ultrasonic cleaner line that can handle up to 5 baskets simultaneously can process oil and fuel pumps delivering perfect cleaning results in just 15 minutes. The ultrasonic cleaner dissolves all of the contaminants hidden between and inside slots, during a 5-stage cycle.

The process starts with an immersion cycle that combines an Ultrasonic wash and Jet Spray technology. to remove the heaviest contaminants.

An immersion wash cycle with vertical basket agitation that combines Ultrasonic washing, Sonicjet and Jet spray cleaning, resulting in a contaminant free component

A tap water rinse designed to remove detergent residues with air bubble agitation to promote efficiency.

A thermal tank equipped with a heat-insulated lid, and HEPA filters recirculate hot air through the parts.

The final stage consists of a vacuum drying cycle ensuring the component emerges 100% clean, dry, and ready for inspection.
