DYC

DYC makes precision metal components, such as shafts, flanges, pinions, differential cases, yokes, and ring gears, that transfer power inside a vehicle's drivetrain, keeping the wheels turning.

It supplies these parts to automakers and their tier-one suppliers worldwide, covering passenger cars, commercial vehicles, and SUVs. Listed on KOSDAQ, Korea's tech and small-cap exchange, the company built its core expertise around friction-welding, a joining technique it was the first in Korea to apply to drivetrain parts, alongside advanced heat-treatment and materials processing. A subsidiary, DYC Dynamics, operates in the defense industry.
