Founded in 1957, Hytek Finishes began as Heath Plating in Kent, Washington to support the metal finishing requirements of the Heath Tecna Plastics Company, in addition to numerous aerospace suppliers in the Seattle area.

Hytek’s growth and Criton’s merge with Esterline Technologies in 1987 enabled us to design, build and move into our current 100,000 square foot facility in 1989. This facility was built to our specifications, creating a flexible highly environmentally compliant finishing facility. Hytek’s approval base expanded rapidly beyond Boeing into OEM support for Airbus, BAE, Lockheed, Bell Helicopters, Goodrich Corporation, Gulfstream, Vought and many others.

In 2019 Esterline merged with The TransDigm Group and Hytek became a unit of TransDigm.

Hytek provides all the services that ensure parts are ready for further assembly and installation in the aircraft, as well as providing long-term corrosion and wear protection to ensure that these aircraft will operate safely now and in the future.
