Trunnion forgings are forgings that utilize forging equipment to apply an external force to a metal billet, causing it to deform plastically so as to obtain the desired geometric shape and quality. In the field of aviation, trunnion forgings are usually used to connect and support various rotating parts, such as engine blades, propellers, etc., to ensure the stability and safety of the aircraft in flight.
