AMT MIM Focus
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, 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
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 density and strength, plus tailored magnetic, corrosion, and thermal performance, make MIM ideal for complex features and thin sections.
Materials Portfolio and Development Capabilities
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 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.
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 lifecycle performance.
Process Innovations and Applications
AMT’s process toolbox widens design and assembly options, 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.
Controlled thin-wall processing supports slim housings and delicate surgical instruments.
AMT has received MPIF Grand Prizes and EPMA recognition for its innovations, including complex In-Coring® parts used in automotive and analytical applications.
High-volume medical production includes robotic-surgery and disposable instruments (200,000+/month), while large hermetic Kovar housings showcase leak-tight precision assemblies.
