How Mitsui MES Brings Real-Time Visibility to its Manufacturing Work-In-Process

Japan’s Mitsui Engineering & Shipbuilding (MES) is a global engineering company that specializes in marine vessels, energy systems, and infrastructure. The company has deployed Xerafy’s Mercury METAL SKIN RFID labels at its MES Oita Works facility for its work-in-process (WIP) management. The MES Oita Works facility produces material handling equipment including container cranes, gantry cranes, overhead cranes, jib cranes, ship cranes, and other machines.

Work-In-Process

As ports around the world invest and expand their facilities, demand for material handling equipment has increased. This surge in orders for MES’ cranes has put further pressure on the company to improve production efficiency.

Handling 55,000 components

The cranes include tens of thousands of parts, many of which are produced at vendor factories.

 

In the past, it has been challenging for MES Oita Works to manage the large number of metal components delivered to the facility daily from those vendors. 

 

The parts had to be sorted according to job numbers by manually referencing an order sheet, engineering drawings, and other documents.

“A big crane typically consists of as many as 55,000 components, from small to large,” says Mr. Sotome, a manager of the Manufacturing Dept. of MES Oita Works. “We experienced difficulties managing the large number of metal components from different vendors and manually sorting and tracking those parts throughout the production process.”

RFID labels for item-level tracking

Xerafy began working with MES Oita Works in June 2016. MES selected Xerafy’s Mercury METAL SKIN labels for their high performance and durability in outdoor conditions to track components, enabling end-to-end tracking using RFID readers at the Oita Works facility.

 

The tags are pre-associated with the order data, printed using RFID printers, and then supplied to the vendors when the orders are placed.

The vendors now pre-tag the parts and components prior to delivery to Oita Works. Each vendor receives a new order sheet and corresponding RFID labels when they deliver the completed components to the facility.

Productivity and streamlined processes

The RFID solution has saved time during production and improved inventory management accuracy. Before the RFID system was deployed, workers at each production site had to go to the stockyard to determine if the components they needed had been delivered and to receive if available. This wasted valuable time during production.

 

Using RFID, the time required for acceptance of those components from the vendors has been reduced, so staff working in the receiving area can provide more timely delivery of components to each production site by checking the progress of production.

“MES is always looking for ways to improve productivity and streamline processes” said Mr. Sotome of MES. “Timely delivery service to production sites requires integration with real-time production data. The system, which started out as a way to simply improve the efficiency of components acceptance, is now showing us how the Oita Works can effectively leverage the Internet of Things.”

Xerafy is a pioneer in Industrial RFID, bringing to market several innovations that enable advanced industrial identification and automation capabilities. In addition to a complete range of field-proven RFID tags available off-the-shelf, Xerafy offers Custom RFID Tags services, covering everything from a personalization service bureau to custom-design engineering capabilities.
