Atlantic Sintered – Precision Powder Metal Components for Global Security and Power Tool Systems
A Massachusetts Legacy with Global Impact
With a history dating back to 1943, Atlantic Sintered has been a reliable partner to the lock and power tool industries for over 80 years. Based in Massachusetts, we bring together decades of powder metallurgy expertise and advanced engineering to deliver high-performance, precision components for demanding applications worldwide.
Whether it's high-strength lock bolts for steering columns in Germany or precision pawls in handheld power tools in Japan, Atlantic Sintered's products are trusted by OEMs and Tier 1 suppliers around the globe. Our Massachusetts facility combines vertically integrated manufacturing with scalable production, enabling us to serve customers locally in New England and across North America, Europe, and Asia.
Engineered Components for Locking Systems and Power Tools
Locks and power tools require components that can withstand repeated stress, provide precise movement, and offer long-lasting durability. At Atlantic Sintered, we specialize in powder metal (PM) manufacturing, which enables near-net-shape production of intricate, high-density, wear-resistant components—all at scale and with exceptional repeatability.
Common Powder Metal Components We Produce:
- Lock Pawls
- Automotive Steering Column Lock Bolts
- Pin Tumblers
- Cylinder Cores
- Power Tool Ratchets and Pawls
- Hammer Mechanisms
- Cam Locks
- Indexing Discs and Collars
We understand the critical nature of precision and strength in both mechanical lock systems and high-speed, torque-intensive power tools. That’s why we tailor every component’s material blend, compaction process, and secondary operations to its intended end-use.
Advantages of Powder Metallurgy for Lock and Power Tool Parts
Powder Metallurgy (PM) is a proven, cost-effective manufacturing process especially suited for producing high-strength, tight-tolerance components in large volumes. It's ideal for lock and power tool components due to the following advantages:
Benefits for Your Components:
- Near-Net Shape Forming: Minimal or no machining required
- Excellent Strength-to-Weight Ratios: Ideal for handheld tools
- High Density for Wear Resistance: Perfect for sliding or impact parts
- Complex Geometries: Undercuts, gear profiles, and multi-level features
- Consistent Dimensions: Reliable performance in precision assemblies
- Efficient Material Utilization: Lower scrap and more sustainable production
These features make PM an excellent solution for parts like lock actuators, trigger mechanisms, rotating couplers, and more.
High Density and High Strength Solutions
In applications where torque, impact, and fatigue resistance are essential—such as in power drills, ratchets, or locking car steering columns—high density components are critical. At Atlantic Sintered, we utilize advanced compaction technologies and material systems to produce components with core densities ranging from 7.1 to 7.4 g/cm³, and where necessary, enhanced surface densification for tooth and sliding surfaces.
High-Density Applications Include:
- Wrench Pawls: Withstand impact and cyclic loading
- Lock Bolts: Resist shear forces in steering columns
- Rotating Couplers: Maintain dimensional integrity under torque
- Hammering Mechanisms: Deliver energy while reducing vibration
Our metallurgical team can help you select the ideal density profile for your specific application, whether you need shock absorption, fatigue strength, or thermal stability.
In-House Secondary Operations and Finishing
Many lock and power tool components require secondary operations to meet precise tolerances or achieve functional surfaces. Atlantic Sintered’s Massachusetts facility is equipped to handle all secondary processing internally—saving time, reducing costs, and improving consistency.
Our In-House Capabilities Include:
- CNC Machining (Turning, Milling, Drilling, Tapping)
- Grinding & Centerless Grinding
- Surface Densification
- Resin Impregnation & Copper Infiltration
- Heat Treatment
- Deburring & Cleaning
- Assembly & Packaging
Every step is performed with quality and precision, ensuring that the final component integrates seamlessly into your product—whether it's a cordless impact wrench or a high-security lockset.
