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 Metal Injection Molding capabilities

AMT can realize shapes that are impractical for traditional 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, supporting both prototypes and high-volume runs (e.g., 200,000+ pieces for surgical tools).

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 a compelling option 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.

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.

Feedstock customization

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.

Material properties achieved

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 and consistency

Each batch is verified via microscopy, density checks, and mechanical testing to meet specifications and standards.

Material selection support

AMT engineers help choose between carbon steels, stainless, tungsten, superalloys, or custom mixes, 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.
