AMT – MIM Manufacturing
AMT targets small, intricate components with tight dimensional control and consistent quality, well-suited to medical, automotive, and electronics applications.
Core MIM capabilities
AMT can realize shapes that are impractical for traditional 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 also minimizes waste in expensive alloys, lowering total cost. High part density and strength, along with tunable magnetic, corrosion, and thermal properties, make MIM ideal for complex features and thin sections.
Materials & Feedstock Development
AMT’s portfolio spans carbon and stainless steels, low-expansion alloys, tungsten and copper, and superalloys such as Inconel, F75, MP35N, and Nimonic 90. Custom alloy development is available to match program requirements.
Available materials
Low-alloy and carbon steels support structural applications, stainless grades add corrosion resistance, and tungsten/copper target density and conductivity needs.
Superalloys withstand high temperatures and creep, benefiting aerospace and medical applications.
Custom feedstock formulation
AMT adjusts powder characteristics, binder systems, and processing windows to fit each project, studying particle morphology, rheology, and debinding behavior to hit targets for strength, magnetism, and thermal performance.
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 & consistency
Each batch is verified via microscopy, density checks, and mechanical testing to meet specifications and standards.
Material selection support
AMT’s team assists with selecting carbon/stainless steels, tungsten, superalloys, or custom blends, balancing cost, manufacturability, and long-term performance.
