Core MIM Manufacturing at AMT
AMT targets small, intricate components with tight dimensional control and consistent quality, ideal for 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, 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 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 alloy development is available to match program requirements.
Available materials
Carbon and low-alloy steels fit structural applications, stainless grades deliver corrosion resistance, and tungsten/copper target density and conductivity needs.
Superalloys withstand high temperatures and creep, benefiting aerospace and medical applications.
Custom feedstock formulation
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.
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
Microscopy, density, and mechanical tests validate every batch to specification and standards.
Application guidance
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 toolbox expands design and assembly possibilities, delivering fewer components and tighter accuracy across both small and large production runs.
In-Coring® enables one-piece parts with internal channels and cavities, 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), to enable features such as integrated magnetic tips on surgical instruments.
Controlled thin-wall processing supports slim housings and delicate surgical instruments.
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.
