Tecnar Accuraspray 4.0

Tecnar Accuraspray 4.0

FST has taken the integration of Tecnar Accuraspray 4.0 to a different level, with full integration in the production system with GO/NO GO signal based on the reference signal.

With the launch of Tecnar’s New Accuraspray 4.0, FST is now able to Real-Time fully automatically check Plasma and HVOF thermal spray system’s plum with only one unique sensor and confirms that the below parameters are within the set specification, before giving the system the go-ahead to start coating the part. Thus, reducing the risk of failures and increases coating quality and production rates.

  • Particle speed
  • Particle temperatures
  • Plum intensity
  • Plum density 
  • Plum deviation
  • Plum width

In addition to assuring that plum parameters are correct, the real-time availability of the Accuraspray 4.0 also helps with:


  • Reducing coating development costs
  • Reducing parameter development times

  • Increase coating quality and consistency
  • Reduce coating failures

  • Increase your earnings
