Work-in-Progress (WIP) Mastery: Streamlining Complex Assembly Lines with RFID

In high-volume production and advanced engineering, the gap between profitability and the bottleneck caused by the deficit is the visibility. The manual tracking of Work-in-Progress (WIP) across conventional assembly systems is ineffective in a complex assembly. Radio Frequency Identification (RFID) offers granular real-time information to convert the fixed assembly lines into a dynamic, intelligent ecosystem.

· How Does RFID Provide Real-Time Visibility In Complex Assembly Lines?

RFID stops the black hole of manufacturing, whereby components lose their ways between stations. The system records the information automatically as the sub-assemblies or chassis containing the ruggedized RFID inventory tracking system move through different production zones.

In contrast to the barcodes, RFID readers can follow items through the paint booths, heat treatment, or high-vibration areas without people's involvement.

This gives a live view of the location of every unit and, as such, will enable the managers to know where exactly a delay is being drawn before it spills over into a complete halt of the line.

·How Can RFID Automate The Manufacturing Execution System (MES)?

Combining RFID and a Manufacturing Execution System (MES) brings about a closed-loop data setting. When a tagged component enters a workstation, a reader is activated by the RFID to show the RFID MES the necessary technical drawings or instructions needed to use this specific SKU.

After finishing the task, the system timestamps the stage and brings a revision to the "Digital Twin" of a product. This automation eliminates the manual input of data that causes human error, and every product that is produced must meet the specifications of its configuration.

·In What Ways Does RFID Reduce Bottlenecks And Production Downtime?

RFID supports the Just-in-Time (JIT) replenishment at the workstation level. The system opens the opportunity to monitor the rate of consumption of WIP components and automatically sends a signal to send parts through a "kanban" to the warehouse in cases where the part is low.

Moreover, in case of a failed quality test of a unit, RFID can be used to perform dynamic routing, meaning that the tagged product could divert to reworking without halting the main line. This is faster sorting and routing that guarantees the facility the highest possible "Up-Time.”

· How Does RFID Improve Quality Control And Traceability In Engineering?

In the case of an industry such as aerospace or automotive, traceability is a regulatory requirement. RFID tags have a permanent history of the technician who performed on a unit, the tools that were used, and the locations of the tools.

In case troubleome lot of parts was noticed after production, RFID can be used to perform surgical recalls.

Rather than recalling a whole month of production time, the engineers can query the database and determine the particular serial numbers that have the damaged unit, which would save millions of possible losses.

Conclusion

Industry 4.0 relies on the ability to master WIP, which can only be achieved by RFID technology. Inventory tracking RFID facilitates engineering companies to increase complexity, rather than reducing speed, by offering autonomous tracking, seamless integration of MES, and traceability of the surgery.

A change to a more RFID-driven assembly line can guarantee that the "Work-in-Progress" is a smooth stream of movement, as opposed to the sequence of disjointed obstacles.
