EDM Recast Layer: How MSI Lab Helps Manufacturers Identify and Eliminate Critical Defects

Electrical Discharge Machining (EDM) creates precision features impossible to achieve through conventional machining—but it also introduces a hidden challenge. The EDM recast layer, a thin altered zone on machined surfaces, can compromise component performance in high-stress applications. At MSI Lab in Dayton, Ohio, we partner with manufacturers to identify, measure, and help eliminate these critical defects before parts reach service.
