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 process covers feedstock preparation, precision molding, debinding, and sintering, backed by rigorous inspection at each stage.

Size, complexity, and volume range

AMT handles micro-scale parts up to components over 4 inches, 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 density and strength, plus tailored magnetic, corrosion, and thermal performance, 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 alloys can be developed per program needs.

Available materials

Low-alloy and carbon steels support structural applications, stainless grades add corrosion resistance, and tungsten/copper target density and conductivity needs.

Superalloys withstand high temperatures and creep, 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

Processes yield dense, reliable parts with tailored tensile strength, magnetic response, and thermal resistance. 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

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

Advanced MIM Methods & Uses

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

In-Coring® enables one-piece parts with internal channels and cavities, 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), to enable features such as integrated magnetic tips on surgical instruments.

Thin-wall capability with warp control supports slim housings and delicate surgical tools.

AMT’s innovations have earned MPIF Grand Prizes and EPMA recognition, including complex In-Coring® parts used in automotive and analytical applications.

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

Key strengths, materials, and applications are summarized below.
