AMT – MIM Manufacturing
AMT focuses on small, intricate parts requiring tight dimensional control and repeatable quality, well-suited to medical, automotive, and electronics applications.
Core MIM capabilities
AMT produces geometries difficult or impossible via subtractive machining, including thin walls, micro-ribs, and internal passages. 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, 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 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.
Available materials
Low-alloy and carbon steels support structural applications, stainless grades deliver corrosion resistance, while tungsten and copper address density and conductivity.
Superalloys withstand high temperatures and creep, serving aerospace and medical uses.
Feedstock customization
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
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
Each batch is verified via microscopy, density checks, and mechanical testing to meet specifications and standards.
Application guidance
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 process toolbox widens design and assembly options, achieving fewer parts and tighter accuracy for small and large runs alike.
In-Coring® creates internal channels and cavities in one piece, removing multi-part joins for components such as 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), and large hermetic Kovar housings demonstrate leak-tight, precision builds.
The table below summarizes strengths, materials, and applications.
| Process Strength | Materials | Representative Applications |
|---|---|---|
| In-Coring® internal channels | Stainless, superalloys, Kovar | SCR nozzles, gas chromatography flow blocks |
