Use Case Scenario

Let’s illustrate how OES creates value with a real-world scenario:

A tertiary steel plant in South Korea faced frequent delays due to alloy inconsistencies in high-strength steel grades destined for automotive clients. These inconsistencies threatened compliance with both mechanical standards and the strict specifications demanded by automakers.

To resolve the issue, the plant installed a high-throughput arc/spark OES system directly on the production floor. Engineers programmed automated sampling at key process points, integrating OES readings into the facility’s MES (Manufacturing Execution System).

The result? Alloy composition issues were detected immediately, enabling corrective actions in real time. Production delays fell by over 25%, scrap rates decreased, and the plant successfully secured a multi-year contract extension with a major automotive manufacturer.

“OES was the game-changer. It transformed our quality control from reactive firefighting to proactive process management,” remarked the plant’s quality director.

This example underscores how OES can deliver substantial returns on investment by ensuring product integrity, reducing downtime, and strengthening customer relationships.
