Powdered Metal Gears
Capstan Atlantic is the largest producer of precision Powdered Metal gears. Our capabilities include high density, high strength gears and our proprietary HD4 process™. Specializing in a large variety of applications, Capstan Atlantic provides solutions for the automotive industry and a wide range of industrial applications.
Gear Tooth Surface densification allows Capstan to respond to our customer's most demanding applications and has the following benefits;
- Results in a P/M gear with similar rolling contact fatigue properties to wrought and forged gears.
- Produces a mirror surface finish to reduce NVH levels.
- Has the ability to crown the gear tooth profile for improved load distribution and minimize noise levels.
- Eliminates secondary operations such as hobbing, shaving, and grinding.
Surface densification provides the cost reduction benefits of the Powdered Metal process while maintaining all the benefits of cut gears.

Precision Gear Measurement Equipment
Capstan Atlantic utilizes advanced gear measurement equipment including in all phases
of the manufacturing process, they include;
HD4™ High Performance Gear System
The HD4™ material system is a Capstan developed system that when combined with surface densification provides outstanding strength and wear properties for the most demanding applications.
The benefits of the HD4™ process are;
- Custom designed high performance alloy system
- Superior core density for fatigue resistance
- Pore free surface density for contact fatigue resistance
- Mirror like surface finish for quiet running gears
- Precise Helix angel
- Custom Involute profiles for noise reduction
- Tailored Hardening process to meet aggressive rolling contact fatigue requirements
- Wrought Steel properties with the economies of Sintered Metal
