AMT MIM Focus
AMT focuses on small, intricate parts requiring tight dimensional control and repeatable 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
From micro-scale components to parts exceeding 4 inches, AMT has coverage, 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.
AMT Materials Portfolio
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.
Material options
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.
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.
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 & consistency
Microscopy, density, and mechanical tests validate every batch to specification and standards.
Application guidance
AMT engineers help choose between carbon steels, stainless, tungsten, superalloys, or custom mixes, balancing cost, manufacturability, and long-term performance.
Advanced MIM Methods & Uses
AMT’s toolbox expands design and assembly possibilities, achieving fewer parts and tighter accuracy for small and large runs alike.
In-Coring® enables one-piece parts with internal channels and cavities, eliminating multi-part joins for items like gas blocks and SCR nozzles.
