Core MIM Manufacturing at AMT
AMT targets small, intricate components with tight dimensional control and consistent quality, well-suited to medical, automotive, and electronics applications.
Core Metal Injection Molding capabilities
AMT can realize shapes that are impractical for traditional machining, such as ultra-thin walls, micro-ribs, and internal channels. The workflow spans feedstock preparation, precision molding, debinding, and sintering, backed by rigorous inspection at each stage.
Size, complexity, and volume range
AMT handles micro-scale parts up to components over 4 inches, serving prototypes through high-volume programs (e.g., 200,000+ surgical components).
Why choose MIM over machining
By consolidating assemblies into one part, MIM cuts assembly time and boosts reliability. It also minimizes waste in expensive alloys, lowering total cost. High part density and strength, along with tunable magnetic, corrosion, and thermal properties, make MIM a compelling option for complex features and thin sections.
AMT Materials Portfolio
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 offer high-temperature and creep resistance, serving aerospace and medical uses.
Feedstock customization
AMT tunes powder, binder, and process windows to project needs, evaluating morphology, flow, and debinding to achieve strength, magnetic, and thermal targets.
Resulting properties
The result is dense, reliable parts with tuned tensile, magnetic, and thermal properties. Alloy selection and heat treatment further refine corrosion and long-term performance.
Testing and consistency
Each batch is verified via microscopy, density checks, and mechanical testing to meet specifications and standards.
Material selection support
AMT engineers help choose between carbon steels, stainless, tungsten, superalloys, or custom mixes, balancing cost, manufacturability, and lifecycle performance.
