AMT – MIM Manufacturing
AMT focuses on small, intricate parts requiring tight dimensional control and repeatable quality, ideal for medical, automotive, and electronics applications.
Core Metal Injection Molding 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, backed by rigorous inspection at each stage.
Size, complexity, and volume range
From micro-scale components to parts exceeding 4 inches, AMT has coverage, supporting both prototypes and high-volume runs (e.g., 200,000+ pieces for surgical tools).
Why choose MIM over machining
MIM consolidates multi-piece assemblies into single, robust parts, reducing assembly time and improving 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 & 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.
Available materials
Carbon and low-alloy steels fit structural applications, stainless grades add corrosion resistance, while tungsten and copper address density and conductivity.
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 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 engineers help choose between carbon steels, stainless, tungsten, superalloys, or custom mixes, balancing cost, manufacturability, and long-term performance.
Innovative MIM Process Technologies 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® 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 merges dissimilar metals—magnetic/non-magnetic, hard/ductile— to enable features such as integrated magnetic tips on surgical instruments.
Controlled thin-wall processing supports slim housings and delicate surgical instruments.
AMT has received MPIF Grand Prizes and EPMA recognition for its innovations, 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.
