Core MIM Manufacturing at AMT

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, including thin walls, micro-ribs, and internal passages. 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

MIM consolidates multi-piece assemblies into single, robust parts, reducing assembly time and improving reliability. It reduces scrap in costly materials, lowering overall 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 & Feedstock Development

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.

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.

Feedstock customization

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.

Material selection support

AMT engineers help choose between carbon steels, stainless, tungsten, superalloys, or custom mixes, balancing cost, manufacturability, and long-term performance.

Innovative MIM Process Technologies and Applications

AMT’s process toolbox widens design and assembly options, delivering fewer components and tighter accuracy across both small and large production runs.

In-Coring® creates internal channels and cavities in one piece, 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), enabling features like integrated magnetic tips on surgical instruments.

Controlled thin-wall processing supports slim housings and delicate surgical instruments.

AMT has received MPIF Grand Prizes and EPMA recognition for its innovations, including complex In-Coring® parts used in automotive and analytical applications.

High-volume medical production includes robotic-surgery and disposable instruments (200,000+/month), and large hermetic Kovar housings demonstrate leak-tight, precision builds.

The table below summarizes strengths, materials, and applications.
