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, 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
From micro-scale components to parts exceeding 4 inches, AMT has coverage, serving prototypes through high-volume programs (e.g., 200,000+ surgical components).
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 a compelling option for complex features and thin sections.
AMT Materials Portfolio
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.
Material options
Low-alloy and carbon steels support structural applications, stainless grades add corrosion resistance, and tungsten/copper target density and conductivity needs.
Superalloys offer high-temperature and creep resistance, serving aerospace and medical uses.
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.
Material properties achieved
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 engineers help choose between carbon steels, stainless, tungsten, superalloys, or custom mixes, balancing cost, manufacturability, and long-term performance.
Advanced MIM Methods & Uses
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, notably for complex In-Coring® parts 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.
