Aerospace Component Manufacturing Processes

Gearboxes and Engine Cases

Gearboxes are manufactured from robust metals such as steel or aluminum. These metals are shaped through casting or forging and then meticulously machined to create precise spaces for the gears. Once the gears are installed, the entire assembly undergoes treatment to enhance strength and durability before final performance testing.

Engine cases utilize lightweight metals like aluminum. The production involves melting the metal and pouring it into molds. After cooling, the case is machined to meet exact specifications for engine components. Finally, it is coated to resist heat and corrosion and undergoes rigorous safety inspections.
