Aircraft Fastener Coating Machine
Standard Aeronautical fasteners uses a sealant, manually applied, just before installation. Here, a new type of sealant, which cures in air, is applied to threads of fasteners in a nitrogen environment. Then a second coating is applied to seal off air to the first application. The process is based around a cam driven rotary indexer with servo-controlled applicators with a robotic offload into trays, after curing, to make sure the second coating is not compromised, allowing the first coat to cure.
