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, such as ultra-thin walls, micro-ribs, and internal channels. The process covers feedstock preparation, precision molding, debinding, and sintering, backed by rigorous inspection at each stage.
Range of part sizes, complexities, and volumes
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
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 a compelling option 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 alloy development is available to match program requirements.
Available materials
Carbon and low-alloy steels fit structural applications, stainless grades add 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, evaluating morphology, flow, and debinding to achieve strength, magnetic, and thermal targets.
Resulting properties
The result is dense, reliable parts with tuned tensile, magnetic, and thermal properties. Alloy choice and heat treatment refine corrosion resistance and long-term durability.
Testing and 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.
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® creates internal channels and cavities in one piece, 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 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), and large hermetic Kovar housings demonstrate leak-tight, precision builds.
Key strengths, materials, and applications are summarized below.
| Process Strength | Materials | Applications |
|---|---|---|
| In-Coring® internal passages | Stainless, superalloys, Kovar | SCR nozzles; GC flow blocks |
