AMT handles micro-scale parts up to components over 4 inches, 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 density and strength, plus tailored magnetic, corrosion, and thermal performance, make MIM ideal for complex features and thin sections.
Materials & Feedstock Development
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 deliver corrosion resistance, and tungsten/copper target density and conductivity needs.
Superalloys withstand high temperatures and creep, serving aerospace and medical uses.
Feedstock customization
AMT tunes powder, binder, and process windows to project needs, 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 and consistency
Each batch is verified via microscopy, density checks, and mechanical testing to meet specifications and standards.
Material selection support
AMT’s team assists with selecting carbon/stainless steels, tungsten, superalloys, or custom blends, balancing cost, manufacturability, and long-term performance.
Process Innovations and Applications
AMT’s toolbox expands design and assembly possibilities, 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.
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), and large hermetic Kovar housings demonstrate leak-tight, precision builds.
