Core MIM Manufacturing at AMT

AMT focuses on small, intricate parts requiring tight dimensional control and repeatable quality, well-suited to 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, 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 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 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

Carbon and low-alloy steels fit 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.

Feedstock customization

AMT adjusts powder characteristics, binder systems, and processing windows to fit each project, 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’s team assists with selecting carbon/stainless steels, tungsten, superalloys, or custom blends, balancing cost, manufacturability, and lifecycle performance.

Advanced MIM Methods & Uses

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, eliminating multi-part joins for items like 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.

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.

The table below summarizes strengths, materials, and applications.

Strength Typical Materials Applications
In-Coring® internal channels Stainless steels, superalloys, Kovar SCR nozzles, gas chromatography flow blocks
Bi-material integration Magnetic/non-magnetic steels; copper alloys Integrated magnetic retention; hybrid instrument tips
Thin-walls (<0.3 mm) Stainless; copper; tungsten blends Hermetic housings, thin clamps, precision shims

Designers can simplify parts, cut costs, and enhance performance using these methods. AMT continues to refine its toolkit to reliably produce complex geometries.
