ACA delivers proven leak testing solutions that help manufacturers improve efficiency, accuracy, and long-term product reliability. Our team designs and integrates leak test systems tailored to the material, geometry, and performance requirements of your parts, providing repeatable results and traceable data across every cycle.
Common Applications:
- Pressure Decay – Detect leaks through precise pressure loss measurement.
- Creep/Crack Testing – Identify structural weaknesses before parts enter production.
- Chamber Testing – Validate sealed components with controlled test environments.
- Flow Testing – Verify proper flow rates for critical assemblies or fluid paths.
- Occlusion Testing – Confirm blockages or restrictions that could affect system performance.
Featured Case Study
Leak Tester – Injection Molded Parts
Challenge: Build stations that test the integrity of various injection molded parts.
Solution: This piece of Leak Test Equipment consists of two identical nests to hold the parts, two leak detectors and two vibrating pin markers. The operator opens a drawer to access the part nests and load the parts. The parts nest onto a post that seals off the larger tube port. Once the operator closes the drawer, a sensor signals the machine to start. A cylinder attached to the drawer holds the drawer closed. Two additional cylinders seal off the other ports on the part. These cylinders have through holes and tubes that are connected to the two leak testers.
The leak tester performs a pressure test to check for voids, short shots, and incomplete welds. Once the parts pass inspection, the markers stamp a Julian date code on each part. The cylinders then retract, and the drawer opens allowing the operator to unload the parts and reload for the next cycle.
