CHALLENGE

  • Leak test multiple sizes diffusers with common tooling
  • High throughput, fast cycle time
  • Challenging seal interface
  • Simulated parts for calibration and validation

SOLUTION 

  • Helium hard vacuum leak test method
  • Dual vacuum test chambers and leak detectors for high speed
  • Automated chamber open and close with safety light curtains
  • Automated calibration with helium supply and calibrated leaks built into dummy parts

SPECIFICATIONS

  • Test Method:  Helium hard vacuum
  • Leak rate:  1 x 10-5 atmcc/sec helium
  • Throughput:  Approximately 1 parts every 8 seconds
