APA was recently contracted by a client who worked with military vehicles to produce a custom testing fixture that would test specific components within special military vehicle systems.
For this project to be successful, the client needed us to meet all customer specifications for correct wiring connections, and to provide very precise placement, spacing, and orientation of all fixture components.
Combining our electronic box build assembly services with our top-notch wiring operations, we were able to build this fixture, fulfilling all of our client’s requirements while meeting IPC-WHMA-A-620 workmanship standards.To begin this project, we first had to purchase sheet metal fabrication for the enclosure, along with a plain plastic face panel. After all needed parts and materials were procured, we used a combination of our drill press, Greenlee punches, and milling machinery to perform all necessary drilling, punching, and cutting operations to fashion the fixture’s various features. We also engraved all characters. These processes had to be carried out very precisely to meet our customer’s exact specifications.
Using our Komax wire processor and Schlueniger strippers, we then proceeded to strip and cut all wires. We also employed our AMP Press to perform all terminal crimping necessary to successfully terminate each connector.
We then attached all wires, including special thermocouple connectors, and installed all other components per our customer’s material list and drawing. After manufacturing and assembly was completed, the testing fixture measured approximately 36 inches high, 24 inches wide, and 9 inches deep. This product also weighed 50 pounds and featured a DIN rail used for mounting circuit breakers and other industrial control equipment inside equipment racks.
After all in-process and final visual inspection, including electrical power-up testing, was performed, we shipped the vehicle test box to our client’s facility in Melrose Park, Illinois. Successfully meeting all of our client’s exact specifications for wiring connections and component placement, APA was able to effectively build a custom testing fixture for the special military vehicle systems industry.
