Reliable Evaluation for Reliable Manufacturing In manufacturing environments, material validation is an ongoing responsibility rather than a single checkpoint. A production-oriented customer required periodic rod testing to verify material integrity before introducing it into their assembly process. Their priority was clear—consistent measurements, transparent reporting, and dependable performance across batches. The engagement began with a controlled trial phase. Initial samples were analyzed to assess measurement stability and reporting structure....

The Value of Time and Understanding Magnetic testing of electrical steel using an Epstein tester for electrical steel can technically be completed in about thirty minutes. The process is structured, precise, and standardized.But what truly creates value is not the time taken to perform the test — it is the time invested in understanding the customer. A customer approached us with a single sheet of electrical steel for...

How Can Non-Standard Geometries Meet International Magnetic Testing Standards? A global technology company required detailed magnetic testing of plate-shaped materials for research and product development. Since magnetic properties directly influenced application performance, accurate characterization was essential for design validation and future production planning. Direct testing in plate form did not permit controlled magnetic flux closure. Without continuous flux circulation, BH loop measurements can be affected by edge effects,...

Reliable Magnetic Testing for Vendor Development A leading automotive component manufacturer initiated a vendor development program following China’s restrictionson magnet exports, which posed a significant supply chain risk. Traditionally, the manufacturer had relied on magnetssourced from China. With supply uncertainty increasing, they identified an alternate supplier and required reliablemagnetic testing to compare the magnetic performance of the alternate supplier’s material against established China-sourced magnets before approving the new...
