A manufacturer of body armor required a leak test system to test the ballistic material for bulletproof vests sealed protective packaging. Traditional test method of packaging using bubble-immersion leak testing was messy, slow and lacked the sensitivity required. In addition, water ingress into a defective packaging would render the contents (ballistic material) unusable. Customer requirements included: 

  • Detect leaks to prevent water ingress into product packaging
  • Ability to detect gross leaks as well as small pinhole leaks
  • Test multiple product sizes and configurations
  • Limited equipment budget

Based on these requirements, LACO engineered a custom force decay leak test system with dual vacuum chambers. Force decay methodology allows for non-destructive leak testing with the ability to identify both gross leaks as well as fine leaks. 

Key Features

  • Custom engineered system using standard leak testing platform
  • Dual chamber test system with an integrated force gauge in each chamber
  • Vacuum pump used to inflate the product
  • Various inserts to accommodate various product sizes
  • Serial interface to customer data logging system
