AMT MIM Focus
AMT targets small, intricate components with tight dimensional control and consistent quality, ideal for medical, automotive, and electronics applications.
Core Metal Injection Molding capabilities
AMT produces geometries difficult or impossible via subtractive machining, including thin walls, micro-ribs, and internal passages. The workflow spans feedstock preparation, precision molding, debinding, and sintering, backed by rigorous inspection at each stage.
Range of part sizes, complexities, and volumes
From micro-scale components to parts exceeding 4 inches, AMT has coverage, supporting both prototypes and high-volume runs (e.g., 200,000+ pieces for surgical tools).
Why choose MIM over machining
By consolidating assemblies into one part, MIM cuts assembly time and boosts reliability. It reduces scrap in costly materials, lowering overall cost. High density and strength, plus tailored magnetic, corrosion, and thermal performance, make MIM ideal for complex features and thin sections.
