Core MIM Manufacturing at AMT
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, such as ultra-thin walls, micro-ribs, and internal channels. The workflow spans feedstock preparation, precision molding, debinding, and sintering, backed by rigorous inspection at each stage.

Material options
Low-alloy and carbon steels support structural applications, stainless grades add corrosion resistance, while tungsten and copper address density and conductivity.
Superalloys withstand high temperatures and creep, benefiting aerospace and medical applications.
Feedstock customization
AMT adjusts powder characteristics, binder systems, and processing windows to fit each project, studying particle morphology, rheology, and debinding behavior to hit targets for strength, magnetism, and thermal performance.
Material properties achieved
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 long-term performance.
