AMT – MIM Manufacturing
AMT focuses on small, intricate parts requiring tight dimensional control and repeatable quality, well-suited to medical, automotive, and electronics applications.
Core MIM 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.
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 offers carbon steels, stainless steels, low-expansion alloys, tungsten, copper, and superalloys (Inconel, F75, MP35N, Nimonic 90). Custom alloy development is available to match program requirements.
Material options
Low-alloy and carbon steels support 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.
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 selection and heat treatment further refine corrosion and long-term performance.
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.
Process Innovations and Applications
AMT’s toolbox expands design and assembly possibilities, 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 merges dissimilar metals—magnetic/non-magnetic, hard/ductile— enabling features like integrated magnetic tips on surgical instruments.
Controlled thin-wall processing supports slim housings and delicate surgical instruments.
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), while large hermetic Kovar housings showcase leak-tight precision assemblies.
