Powder metallurgy involves seamless coordination of materials, tooling, machinery, manpower, and processes. In all operations – from powder receipt and mixing, to compaction, green part handling, sintering, testing, and certification – data is being generated. However, the information is typically spread out among various machines, spreadsheets, manual logbooks, sensors, and software applications.
The important point now is not how data can be collected anymore. It is how the connections between data can be facilitated in order to make better decisions more quickly.
This is where Artificial Intelligence along with the Internet of Things (AIoT) technology can help.
Getting the Right Perspective on Manufacturing Operations
A typical powder metallurgy facility operates multiple powder grades, batches, dies, punches, fixturing, and maintenance assets. At the same time, production crews have to ensure a constant flow of compaction into sintering. Quality and EHS departments need reliable traceability and safety data.
AIoT provides a layer of intelligence around these processes. RFID is able to provide tracking of tooling and physical assets, while BLE allows for workforce tracking and zoning. Industrial IoT sensors can provide monitoring of equipment condition, vibration, particle levels, and environmental variables. LoRaWAN allows connectivity between the sensors in large facilities or multiple buildings.
Further, analysis of the above-mentioned data through AI is able to detect patterns and provide operational insights and notifications.
Enhancement of Tooling and Inventory Optimization
RFID system on a basic level would give the location of the die. Intelligent systems will incorporate information regarding location of the die with the production cycles, maintenance, and usage. Thus, this information is useful in planning of maintenance, validation of tooling changes, utilization analysis, and production scheduling.
Moreover, the powder inventory can be optimized using connected analysis of production schedule, historical data of powder usage, existing stocks, and purchasing patterns.
Connectivity of Pressing, Sintering, and Traceability
Visibility of work in progress is necessary to ensure that production flows smoothly. Tracking systems are able to indicate at what stages the parts are stored.
AIoT technology can also allow for the digital provenance of materials. A fully developed part can be traced back to its respective lot of powders, mixing process, compaction process, furnace run, inspection data, and certification data. Quality investigations and documentation will thus become more systematic.
Visibility Assistance for Improved Safety
Connected badges, RFID credentials, BLE technology, and environmental sensors can provide additional visibility in a controlled environment for handling powders. Combining worker location data and environmental monitoring data could reveal certain patterns regarding either occupancy or particulate exposure. These should assist but not replace existing EHS protocols.
The Practical Opportunity
The future of powder metallurgy will not be solely defined by additional sensors but will focus on linking people, machinery, materials, processes, and data.
Products like PowderForge AI can achieve an AIoT approach through integration of AI, RFID, BLE, LoRaWAN, industrial IoT, and analytics for powder metallurgy operations.
The most practical way to begin could be with solving one of those challenges: tooling, inventory, WIP, safety, or traceability. With access to operational data, AI can convert that into valuable manufacturing intelligence.
