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.
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).
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 part density and strength, along with tunable magnetic, corrosion, and thermal properties, 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 alloys can be developed per program needs.
Available materials
Carbon and low-alloy steels fit structural applications, stainless grades deliver 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 adjusts powder characteristics, binder systems, and processing windows to fit each project, evaluating morphology, flow, and debinding to achieve strength, magnetic, and thermal targets.
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
Microscopy, density, and mechanical tests validate every batch to specification and standards.
Application guidance
AMT engineers help choose between carbon steels, stainless, tungsten, superalloys, or custom mixes, balancing cost, manufacturability, and long-term 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 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 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 production includes robotic-surgery and disposable instruments (200,000+/month), and large hermetic Kovar housings demonstrate leak-tight, precision builds.
The table below summarizes strengths, materials, and applications.
