About Us

Hytek serves the Aerospace & Defense industry’s surface finishing and testing needs.

Our MRO services allow these same parts to be ‘brought back to life’ for decades more service.

About Us

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.

The majority of parts Hytek processes are high heat treat, structural components of assemblies. Landing gear components, wing structures and moving elements that require not only corrosion protection but special coatings related to their movement and interaction with other parts.

Hytek’s processes include Non Destructive Testing of all substrates; Chrome, Grinding, Cadmium, Titanium Cadmium, Nickel and Zinc Nickel Plating; Shot Peening; Boric, Chromic, Sulfuric and Hardcoat Anodize; All types of Organic coatings/paints including primers, sol gel, dri lubes, aluminized coatings and topcoats.

Hytek is a ‘One Stop Shop’ for aerospace finishing. The breadth of finishes available in this building allow customers to minimize lead times and extra PO’s. This has driven our growth with customers outside the Pacific Northwest.

We hold hundreds of specification approvals from all major OEMs. We work for over 500 machine shops across North America. We are a Tier 1 Boeing supplier for some parts and their largest direct offload supplier.


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.

In 1982, Heath Tecna became a part of Criton Technologies, a Bellevue, Washington based company specializing in aerospace, defense and commercial products and services. At this time, Heath Plating became known as today’s Hytek Finishes.

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 is AS9100 Rev D Registered and is Nadcap accredited for NDT, Chemical Processing and Shot Peen.
