AMT – MIM Manufacturing
AMT targets small, intricate components with tight dimensional control and consistent quality, well-suited to medical, automotive, and electronics applications.
Core Metal Injection Molding capabilities
AMT produces geometries difficult or impossible via subtractive machining, such as ultra-thin walls, micro-ribs, and internal channels. The workflow spans 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
By consolidating assemblies into one part, MIM cuts assembly time and boosts 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.
AMT Materials Portfolio
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, while tungsten and copper address density and conductivity.
Superalloys offer high-temperature and creep resistance, benefiting aerospace and medical applications.
Custom feedstock formulation
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.
Resulting properties
The result is dense, reliable parts with tuned tensile, magnetic, and thermal properties. Alloy choice and heat treatment refine corrosion resistance and long-term durability.
Testing & consistency
Each batch is verified via microscopy, density checks, and mechanical testing to meet specifications and standards.
Application guidance
