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 can realize shapes that are impractical for traditional machining, including thin walls, micro-ribs, and internal passages. The workflow spans 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
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 density and strength, plus tailored magnetic, corrosion, and thermal performance, 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.
Material options
Carbon and low-alloy steels fit structural applications, stainless grades add 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, 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 selection and heat treatment further refine corrosion and long-term performance.
Testing & 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 long-term performance.
Process Innovations and Applications
AMT’s toolbox expands design and assembly possibilities, 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.
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, notably for complex In-Coring® parts 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.
| Process Strength | Materials | Applications |
|---|---|---|
| In-Coring® internal passages | Stainless, 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 surgical clamps; precision shims |
These methods help designers simplify parts, reduce cost, and improve performance. AMT continues refining its toolkit for reliable production of complex shapes.
