Hytek Finishes Co.

Hytek Finishes is a surface finishing company in Kent, Washington. It serves the aerospace, defense and space markets. It also serves commercial, electronics and medical customers. The site says it has more than 60 years of experience.

The company began in 1957 as Heath Plating. It first served the Heath Tecna Plastics Company and aerospace suppliers around Seattle. In 1982 Heath Tecna joined Criton Technologies, and the business took the name Hytek Finishes. In 1989 it moved into its present plant of 100,000 square feet.

Its services cover many steps. These include chrome, grinding, cadmium, titanium cadmium, nickel and zinc nickel plating. Others are passivation, shot peening, titanium etch and polishing. Shot peening hits a metal surface with small beads to make it stronger.

Anodizing includes sulfuric, boric, chromic and hardcoat types. Anodizing builds a hard oxide layer on metal. The company also applies chemical conversion coatings. Painting covers primers, fuel tank coatings, topcoats, dry lubricants, aluminized coatings and intumescent coatings.

Testing is done in house. It includes fluorescent penetrant, magnetic particle and nital etch inspection. The site says the company holds over 800 specifications and runs a full lab. It also processes zinc spray for Airbus and magnesium to AMS2700 standards.

Most parts are high strength structural pieces, such as landing gear parts, wing structures and moving elements. They need corrosion protection and special coatings. The site says the company also offers MRO services that bring parts back to service for decades more.

The site says the company holds hundreds of approvals from major OEMs. It works for over 500 machine shops in North America. It is a Tier 1 Boeing supplier for some parts. Customers come from the United States, North America, Europe and Asia. Having all steps in one building cuts lead times and extra purchase orders.
