AMT MIM Focus
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 can realize shapes that are impractical for traditional machining, including thin walls, micro-ribs, and internal passages. The process covers feedstock preparation, precision molding, debinding, and sintering, with rigorous inspection throughout.
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 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 & Feedstock Development
AMT offers carbon steels, stainless steels, low-expansion alloys, tungsten, copper, and superalloys (Inconel, F75, MP35N, Nimonic 90). Custom alloys can be developed per program needs.
Available materials
Carbon and low-alloy steels fit structural applications, stainless grades add corrosion resistance, while tungsten and copper address density and conductivity.
Superalloys offer high-temperature and creep resistance, benefiting aerospace and medical applications.
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
Processes yield dense, reliable parts with tailored tensile strength, magnetic response, and thermal resistance. Alloy choice and heat treatment refine corrosion resistance and long-term durability.
Testing and consistency
Microscopy, density, and mechanical tests validate every batch to specification and standards.
Material selection support
AMT’s team assists with selecting carbon/stainless steels, tungsten, superalloys, or custom blends, 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, 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.
Key strengths, materials, and applications are summarized below.
