Global manufacturer of auto safety components required a leak test system for air bag diffusers. Customer requirements included:

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

We engineered a custom leak test system using the helium hard vacuum leak test method and dual vacuum test chambers and leak detectors for fast cycle times. Custom tooled leak test fixtures accommodated multiple part sizes.

Key Features

  • 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
