Our Core Innovations: SolidStir^® Technology

SolidStir^® Extrusion is an advanced solid-state manufacturing process that transforms metal feedstock—such as powders, chips, or recycled scrap—into fully consolidated extrudates without melting. By leveraging frictional heat and intense plastic deformation, this continuous process produces dense, fine-grained extrusions with superior mechanical properties and excellent surface finish. Unlike conventional hot extrusion, SolidStir^® operates at significantly lower temperatures, which reduces energy consumption and preserves material integrity. The process eliminates the need for lubricants or die heaters and supports high material utilization, making it ideal for sustainable manufacturing. SolidStir^® Extrusion is particularly effective for processing lightweight and hard-to-extrude materials like aluminum alloys, magnesium, and metal matrix composites. It also enables dissimilar or gradient material extrusion, opening new possibilities in the design and production of structural components for aerospace, transportation, and circular economy applications.
