Client: Medical Device Manufacturer
Technology: Acoustic Resonance Testing AT
The client part was a very small CO2 gas cartridge used to power the injection of medicine. The gas canisters in these devices are made from steel, which is inherently porous. Due to either porosity or manufacturing process inconsistences, the cartridges must be inspected to ensure they are full prior to assembly into the client’s product. For this reason, the Medical Device Manufacturer mandated that their sub contract manufacturers included some form of inspection to ensure full cartridges.
AMS developed an automated Acoustic Resonance Inspection System, which ran at an exceptionally high speed. The system allowed the Medical Device Manufacturer to simply feed cartridges into the machine, and the machine, in turn, ensured both proper fill and pressure. Failed parts were fed into a reject containment system and the accepted parts were then fed to the next process in the assembly operation.
- The contract requirement for 100 percent inspection of the CO2 gas cartridges was fulfilled at a minimal added cycle time and minimal client expense.
- Demanding end user quality requirements were met because non-conforming parts were contained.
