This white paper explores how Nemak, a global leader in automotive components, uses Lumafield’s industrial CT scanning to tackle porosity challenges in aluminum high-pressure die casting (HPDC) for transmission housings. Traditional inspection methods like ultrasound and fluoroscopy often fall short in detecting and characterizing internal defects. Lumafield’s CT platform provides rapid, non-destructive 3D imaging and automated analysis, allowing engineers to visualize porosity in context, understand root causes, and iterate faster. By integrating CT into their workflow, Nemak significantly reduced analysis time, improved process control, cut scrap, and enhanced their ability to meet tight automotive quality standards.
