Size, complexity, and volume range
AMT handles micro-scale parts up to components over 4 inches, supporting both prototypes and high-volume runs (e.g., 200,000+ pieces for surgical tools).
Benefits of MIM vs. conventional 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 ideal 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 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 withstand high temperatures and creep, benefiting aerospace and medical applications.
Feedstock customization
AMT tunes powder, binder, and process windows to project needs, evaluating morphology, flow, and debinding to achieve strength, magnetic, and thermal targets.
Resulting properties
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 & 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.
Advanced MIM Methods & Uses
