Can We Speed Up Large Volume Part Leak Testing by Eliminating Filler Blocks?
The Challenge:
- Oil pans require leak testing—a production step historically slowed by the relative large volume of each part. Traditionally, filler blocks are incorporated into the test process in order to reduce the test volume making the leak test cycle both more accurate and relatively faster. Loading and unloading filler blocks do add time to the production process. But without filler blocks, the stabilization phase of testing proceeds too slowly and with too much error.
The InterTech Solution:
- InterTech Development Company engineers a leak test system where oil pans are tested to a 10 sccm limit, at a pressure of 100kPa (14.5psig) within 19 seconds.
- This fast production rate is achieved without filler blocks. InterTech’s fast oil pan leak test system includes:
- Superior test accuracy and at faster speeds using the InterTech M1075 Mass Flow Leak Detector to control the test cycle 
Unlike generic test instruments, InterTech’s mass flow leak testers use patented sensors that are tuned to perform optimally and most sensitively within the test parameters required for testing these large volume oil pans.
