When your part design involves complex challenges, traditional manufacturing methods often fall short compared to a Metal Injection Molding process. Engineers and project teams continually face the difficulty of balancing design complexity, performance standards and supplier reliability.
AMT is a leader in Metal Injection Molding (MIM) manufacturing, helping you overcome these challenges. Our advanced facilities feature a dedicated cleanroom and assembly facility, supporting research, development, manufacturing, and commercial applications. With a team of skilled engineers, R&D specialists, and manufacturing experts, we continuously refine our Metal Injection Molding processes to deliver exceptional performance, scalability, and quality.
Our Metal Injection Molding (MIM) Process
Our Metal Injection Molding process consists of four key stages: Mixing, Injection, Debinding, and Sintering. Each stage is crucial for producing high-quality final parts. AMT integrates cutting-edge innovations at every process to enhance efficiency in manufacturing.
In-House Feedstock Formulation
At AMT, we produce our own feedstock in-house using a tightly controlled mixing process tailored to each customer’s material and performance requirements. Metal powders and proprietary binders are compounded in a contamination-free environment to ensure exceptional material integrity and homogeneity. Each batch is produced in accordance with MPIF (Metal Powder Industries Federation) material standards, guaranteeing consistent quality, mechanical properties, and compliance with global benchmarks. This in-house capability enables us to maintain full control over feedstock composition delivering superior part reliability and repeatability in every production run.
Advanced Injection Molding Technology
We use advanced injection molding machines to manufacture high-precision metal, ceramic, and copper-based components. Integrated with engineered vision systems and robotic automation, our production lines enable real-time quality monitoring and output tracking. This ensures consistent dimensional accuracy, improved production efficiency, and uncompromising quality control throughout the manufacturing process.
Debinding Technology
AMT employs binder removal through advanced thermal and catalytic debinding technologies, ensuring dimensional integrity prior to sintering.
Thermal debinding efficiently removes binders from molded components through a precisely controlled heating process and meticulous temperature management. This gradual decomposition of binders ensures that the metal structure remains uncompromised, minimizing the risk of defects such as cracking or warping. The result is uniform binder removal and consistently high part quality.
Catalytic debinding utilizes a chemical process to selectively decompose the polymer binder at lower temperatures. This method enables a faster debinding cycle with reduced thermal stress on the component, making it particularly suitable for high-precision parts with fine features.
These debinding technologies provide a flexible removal strategy tailored to material type, part geometry, and production volume.
Vacuum & Air Sintering Furnaces
AMT is equipped with both vacuum and air sintering furnaces, offering precise control of temperature and atmosphere to optimize sintering across a range of materials.
Vacuum furnaces are used for sintering metals and non-ferrous alloys such as stainless steel, copper, tungsten, and nickel-cobalt. The vacuum environment reduces contamination and oxidation, ensuring high material purity, uniform densification, and strong mechanical properties.
Air furnaces are primarily used for ceramics, where an oxidizing atmosphere is critical for achieving the desired microstructure and performance.
Designed for continuous batch processing, these advanced systems support high-volume production while meeting the stringent quality and reliability standards of demanding industries.
