Proving Proper Seal of Sensitive Materials
The effectiveness of a sealing process can be quantified by using the pressure mapping technology, thereby optimizing the packaging design, run-after-run.
During the packaging of medical devices and goods, process consistency is crucial not just for enhancing yields, it could entirely make a difference between life and death. Pressure mapping can help manufacturers stay attuned with their machines in ways no other technology can ensure.
Case Example: Identifying Packaging Defects On-the-Fly
It is crucial to identify defects in product packaging to keep pharmaceuticals hygienic, fresh, and free of damage. When it comes to this application or in the R&D design of a packaging machine, pressure mapping, which is an integrated feature within a machine’s UI, can permit operators to maintain their products safe and secure.
Bonfiglioli Engineering, a packaging machine manufacturer, used a software API to integrate pressure mapping technology into its pill pack sealing machine.
Figure 1 depicts a sensor integrated into the machine’s lid reading pressure distribution at the time of the sealing process. The pressure distribution over the entire pill pack is shown by a display screen, which also detects cavities having low pressure. This valuable information assisted operators in streamlining their machine-setup and quality control investigation, besides enhancing their efficiency.

Troubleshooting Production Processes
Production personnel can employ pressure mapping to travel the same path that their products take, from assembly to completion.
As is the case for any production facility, delicate materials usually go through various types of impacts on their way to assembly. Potential problem areas in a process can be identified by using the pressure mapping technology in machine setup or quality control.
Case Example: Enhancing Spot-Checking Efforts in High-Throughput Operations
A major difficulty faced by production managers and engineers is to reduce damage and loss in a high-throughput pharmaceutical fill line operation. Visual inspection of containers and bottles for damages or scuffs can only help identify a problem that has already occurred at some point of the process; however, it may not be physically feasible to identify exactly where in the process these impacts occurred.
Ultra-thin pressure mapping sensor technology is a valuable technique for improving quality control checkups in fill lines. For example, positioning sensors located along conveyors or rail lines can capture pressure impacts and detect at which points adjustments could be required. Moreover, an effective method to detect errors would be to instrument packaging units with sensors and sending them through the entire production line.

Product Testing and Quality Control
Pressure mapping is a very effective quality control tool for determining the safety and consistency of medical devices and products.
Besides the fact that large-scale product recalls could always prove expensive, they are infinitely compounded considering that human lives are being harmed as a result of poor production oversight and testing. Before the products leave the production facility, pressure mapping technology ensures that they are safe for the treatment of humans and animals.
Case Example: Evaluating Spray Patterns of Metered-Dose Inhalers
Several years of testing and approval measures are needed for each and every medical device before it is commercialized. Despite these stringent measures, potential problems could occur at the production end, which might go undetected until it is too late.
One metered-dose inhaler manufacturer has made pressure mapping technology an important part of its quality control program. At the time of a production run, a batch of inhalers is routinely pulled from the line and sprayed against a pressure mapping sensor to evaluate the spray pattern.
This information can be used by the production personnel to benchmark whether the inhaler’s pressure output is well within a safe range, to detect for potential leaks, as well as to measure whether too little or too much medicine is being delivered.
