AMT – MIM Manufacturing
AMT targets small, intricate components with tight dimensional control and consistent quality, ideal for 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
From micro-scale components to parts exceeding 4 inches, AMT has coverage, serving prototypes through high-volume programs (e.g., 200,000+ surgical components).
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 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 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.
Material options
Carbon and low-alloy steels fit structural applications, stainless grades deliver corrosion resistance, and tungsten/copper target density and conductivity needs.
Superalloys offer high-temperature and creep resistance, serving aerospace and medical uses.
Custom feedstock formulation
AMT tunes powder, binder, and process windows to project needs, 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 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.
