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, with rigorous inspection throughout.
Size, complexity, and volume range
AMT handles micro-scale parts up to components over 4 inches, supporting both prototypes and high-volume runs (e.g., 200,000+ pieces for surgical tools).
Benefits of MIM vs. conventional machining
MIM consolidates multi-piece assemblies into single, robust parts, reducing assembly time and improving reliability. It also minimizes waste in expensive alloys, lowering total 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 alloys can be developed per program needs.
Material options
Low-alloy and carbon steels support structural applications, stainless grades deliver corrosion resistance, while tungsten and copper address density and conductivity.
Superalloys offer high-temperature and creep resistance, 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
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.
Advanced MIM Methods & Uses
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), to enable features such as 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, notably for complex In-Coring® parts 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.
