Case Studies:

Specialty Bolt Hole Sizing
Testing Radiator Tubes for Leaks
Leak Testing Truck Lighting Fixtures

Specialty Bolt Hole Sizing
The customer requires that a specialty bolt be drilled with cross holes for venting hydraulic lines. If a hole is missing, occluded or wrongly sized during the manufacturing process, the lines may be incomplete or obstructed. TME was asked to design an instrument and fixture system that would confirm that a hole exists, is not occluded and the dimensions meet specifications. The basic pneumatic system of the TME Solution™ Leak and Flow Tester coupled with customized software to measure pressure decay and backpressure were used to perform a flow test for occlusion on the customer's part. Using the flexibility of the TME Solution™ and the problem solving skills of the TME engineering team, the customer's needs were met and exceeded for speed, accuracy and repeatability of the test system.

Testing Radiator Tubes for Leaks
The customer manufactures radiator tubes and needed a leak test system. The test required an 80-psig test pressure and a very fast cycle time in order to keep up with automated production of 370 units per hour. The TME Solution™ with four port concurrent leak testing and Memory Reference Curve technology was interfaced with an enclosed fixture that would hold four tubes. The Memory Reference Curve is a technology that allows the operator to store the decay curve of an acceptable unit in the instrument's memory. The TME Solution™ then tests four tubes concurrently, compares their decay curve with the reference in its memory and identifies any parts that are leaking with an audible and visual failure indicator. Testing at 80 psig normally requires an extended stabilization time, but using the Memory Reference Curve all but eliminates this time, making possible a five second cycle time. This cut the customer's overall test time in half.

Leak Testing Truck Lighting Fixtures
The customer manufactures truck lighting units. TME was asked to provide a leak test system that would be accurate, repeatable and very fast in order to help increase productivity. TME engineers developed a system including a fixture designed to seal all holes in the lighting unit and the TME Solution™ leak test instrument with 0.0001-psi resolution. The leak test was performed at a very low pressure. The pressure decay indicating a leak was large enough that the very high resolution of the TME Solution™ was able to detect it in a matter of seconds. The combination of TME engineering expertise and the 0.0001-psi resolution of the test instrument enabled us to decrease the customer's overall test time considerably, significantly increasing his productivity.
