Case

A European medical device manufacturer needed precision gears for surgical robots and imaging equipment. The gears had to operate silently, reliably, and in some cases, be non-magnetic for MRI compatibility.

DDGear supplied custom small-module spur, worm, and plastic gears, manufactured with ISO Class 4 accuracy and materials suitable for medical standards. Rigorous inspection ensured each gear met the tight tolerances required for medical safety.

The result was improved accuracy in surgical applications, extended durability, and reduced machine downtime. The manufacturer gained stronger credibility in the medical sector and expanded its global market share.

A robotics startup in South Korea developing humanoid robots for healthcare and education needed gears that could deliver lifelike, silent movements. Standard gears created noise and backlash, making the robots appear less natural and less reliable for interaction.

DDGear designed precision small-module joint gears with micron-level tolerances and polished surfaces. These gears minimized backlash, reduced noise, and supported smooth torque transfer in elbow, wrist, and actuator assemblies.

With DDGear’s solution, the robots achieved 30% better movement stability and significantly lower noise. This improvement enhanced the robots’ acceptance in sensitive environments such as eldercare facilities, helping the startup secure new clients.
