Automobile
The automotive sector focuses on vehicles powered by internal combustion engines (ICE). These vehicles rely heavily on components like gears, shafts, bearings, and structural assemblies that must withstand high mechanical stress, wear, and temperature fluctuations. Mass production, part repeatability, and cost-efficiency are essential.
