AMT – MIM Manufacturing
AMT focuses on small, intricate parts requiring tight dimensional control and repeatable 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 process covers feedstock preparation, precision molding, debinding, and sintering, with rigorous inspection throughout.
Range of part sizes, complexities, and volumes
AMT handles micro-scale parts up to components over 4 inches, supporting both prototypes and high-volume runs (e.g., 200,000+ pieces for surgical tools).
Benefits of MIM vs. conventional machining
MIM consolidates multi-piece assemblies into single, robust parts, reducing assembly time and improving reliability. It reduces scrap in costly materials, lowering overall cost. High part density and strength, along with tunable magnetic, corrosion, and thermal properties, make MIM ideal for complex features and thin sections.
Materials Portfolio and Development Capabilities
AMT offers carbon steels, stainless steels, low-expansion alloys, tungsten, copper, and superalloys (Inconel, F75, MP35N, Nimonic 90). Custom alloy development is available to match program requirements.
Material options
Low-alloy and carbon steels support structural applications, stainless grades add corrosion resistance, while tungsten and copper address density and conductivity.
Superalloys withstand high temperatures and creep, benefiting aerospace and medical applications.
Custom feedstock formulation
AMT tunes powder, binder, and process windows to project needs, studying particle morphology, rheology, and debinding behavior to hit targets for strength, magnetism, and thermal performance.
Material properties achieved
Processes yield dense, reliable parts with tailored tensile strength, magnetic response, and thermal resistance. Alloy selection and heat treatment further refine corrosion and long-term performance.
Testing & consistency
Microscopy, density, and mechanical tests validate every batch to specification and standards.
Material selection support
AMT engineers help choose between carbon steels, stainless, tungsten, superalloys, or custom mixes, balancing cost, manufacturability, and long-term performance.
