Atlantic Sintered – Scalable Powder Metallurgy for High-Volume Micro Component Production
Massachusetts Innovation with Global Reach
Headquartered in the heart of Massachusetts, Atlantic Sintered is a global leader in the production of micro parts through advanced powder metallurgy (PM). With over 80 years of manufacturing experience, we offer the precision, scalability, and quality control required to produce millions of miniature and micro components per week—defect-free.
Our manufacturing facility, located in one of the most respected industrial hubs in the United States, serves as a center of innovation and excellence. While based in Massachusetts, our micro part production supports OEMs and Tier 1 suppliers across North America, Europe, and Asia—delivering quality at scale for mission-critical applications.
What Are Micro Parts?
Micro parts are small mechanical or electro-mechanical components used in high-precision assemblies. These parts often measure just millimeters in size, yet perform vital roles in everything from automotive locks and actuators to consumer electronics and sound devices.
Atlantic Sintered specializes in high-volume, tight-tolerance production of micro parts that demand:
- Dimensional consistency
- Structural strength
- Reliable repeatability
- Cost-effective mass production
Our micro parts are often engineered to operate within constrained environments or under rigorous mechanical loads. Powder metallurgy allows us to produce complex geometries and intricate features at a lower cost than machining or stamping.
Why Powder Metallurgy for Micro Components?
For manufacturers and engineers designing at the micro scale, powder metallurgy offers several advantages over traditional production methods:
- Net-shape or near-net-shape manufacturing to reduce or eliminate secondary machining
- Excellent dimensional repeatability, ideal for automated assemblies
- Material efficiency, reducing scrap and cost
- Enhanced design flexibility, supporting internal cavities, undercuts, and complex forms
- High throughput, with capability to produce millions of parts per week
- Scalable production, from 5,000 to over 30 million components per year
These benefits make PM the preferred solution for micro parts in high-volume product lines.

- Automated press technology for high-speed, high-precision forming
- Controlled-atmosphere sintering for optimal part strength and dimensional stability
- In-house CNC machining for post-processing or tight-tolerance finishes
- Visual and automated inspection systems for zero-defect assurance
- Batch and continuous production lines for part volumes ranging from 5,000 to 30 million annually
Whether you're developing a new miniature actuator or sourcing high-volume motor pinion gears, Atlantic Sintered delivers micro parts that exceed your technical requirements—at scale.
Standard Applications for Small and Micro Powdered Metal Parts
Our micro parts are used globally in a wide array of industries including automotive, consumer electronics, medical devices, security systems, and aerospace. Applications often involve motion control, sealing, sound generation, or mechanical locking.
Common Micro Components We Manufacture:
- Motor Pinion Gears – Small gear mechanisms for electric motors in automotive and consumer electronics
- Lock Cylinder Components – Precision sintered parts for anti-theft systems, key locks, and door mechanisms
- Sound Actuators – Used in buzzers, alarms, and mobile devices to produce audible signals
- Gasket Components – Sealing elements requiring high-precision dimensional control and wear resistance
- Micro Actuators – Miniature components that convert electrical signals into precise motion
These parts are often invisible to the end user—but essential to the operation and reliability of the entire system.
