The Sona Group, after acquiring Thyssen Krupp’s forging business (which acquired BLW, the inventor of warm forging) and 25% stake of Mitsubishi, renamed the company to Sona BLW Precision Forgings, which became the largest manufacturer of forged gears. In 2019, Sona BLW acquired Comstar Automotive, a leading designer and manufacturer of starting and charging systems for automobiles, and created a new identity.
