The Accuraspray CS advantage

Achieve critical velocity

Cold spray processes are very sensitive to particle velocity. Achieving critical velocity is key to maximizing deposition efficiency and ensuring good coating adhesion. Monitoring the real-time in-flight velocity can help production managers  attain maximum spray time efficiency and coating consistency.

Process stability measurement

Since stability is crucial in spray processes, the Accuraspray CS features a new process stability measurement. This state-of-the-art stability analysis tool sets benchmarks so operators can compare acceptable parameter deviations with real-time standard deviations. This results in increased repeatability and   greater confidence in your measurements.

Best accuracy in the industry

The Accuraspray CS was built on the consistent, easy-to-use Accuraspray 4.0 platform, the benchmark for spray diagnostics in production environments. The Accuraspray CS may be a new product at Tecnar, but it capitalizes on decades of engineering in the Accuraspray family.

The velocity measurements are factory calibrated using a NIST traceable calibration bench to recreate the conditions experienced in the field and filtering algorithms display values you know you can trust. 

Save time

  • Quicker spray parameter development  and process optimization
  • Easy parameter transfer and replication from booth to booth
  • Quicker equipment qualification for new guns and powders
  • Quicker coating qualification due to no bad coating coupons

Live feed rate

The Accuraspray CS measures  the light reflected by the particles in the spray plume so you can monitor the feed rate in real time. Predict clogging in the gun, nozzle wear or changing booth conditions by detecting swaying feed rate. The user can also set up correlations for the feed rate with preferred units (g/min or RPM) for a specific powder lot.

Industry 4.0 ready

You’re in control with the Accuraspray CS. It features a modern, web-based user interface, making it easy to access from any computer, anywhere and the interface can be viewed on multiple viewing devices simultaneously. Communication infrastructure via HTTP or external PLC makes full 4.0 booth integration possible, including communication with robots and Go/No Go decisions.

Strip chart displays

The evolution of all measurements over time is visualized on intuitive strip chart displays.

Production reports

Production reports are generated with a single click in the user interface or through digital I/O.

Setup files

The Autoset feature automatically adjusts all important setup parameters according to spray conditions.
