AMT – MIM Manufacturing
AMT targets small, intricate components with tight dimensional control and consistent quality, ideal for medical, automotive, and electronics applications.
Core MIM capabilities
AMT produces geometries difficult or impossible via subtractive machining, such as ultra-thin walls, micro-ribs, and internal channels. The process covers feedstock preparation, precision molding, debinding, and sintering, with rigorous inspection throughout.
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 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.
AMT Materials Portfolio
AMT offers carbon steels, stainless steels, low-expansion alloys, tungsten, copper, and superalloys (Inconel, F75, MP35N, Nimonic 90). Custom alloys can be developed per program needs.
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 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
Processes yield dense, reliable parts with tailored tensile strength, magnetic response, and thermal resistance. Alloy choice and heat treatment refine corrosion resistance and long-term durability.
Testing & 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.
Innovative MIM Process Technologies and Applications
AMT’s toolbox expands design and assembly possibilities, delivering fewer components and tighter accuracy across both small and large production runs.
In-Coring® enables one-piece parts with internal channels and cavities, eliminating multi-part joins for items like gas blocks and SCR nozzles.
Bi-material integration combines dissimilar metals (e.g., magnetic with non-magnetic, hard with ductile), enabling features like integrated magnetic tips on surgical instruments.
Thin-wall capability with warp control supports slim housings and delicate surgical tools.
AMT’s innovations have earned MPIF Grand Prizes and EPMA recognition, including complex In-Coring® parts used in automotive and analytical applications.
High-volume medical output spans robotic-surgery and disposable instruments (200,000+ per month), while large hermetic Kovar housings showcase leak-tight precision assemblies.
