Who We Serve

Built for the aircraft of today — and tomorrow.

Ohio is becoming a hub for advanced air mobility. Green Tokai is right here, with the capacity, quality systems and engineering support to help aviation programs move from prototype to rate production.

Air Taxi & eVTOL

Advanced Air Mobility OEMs are shifting from certification aircraft to production lines. We know how to scale — that's what automotive suppliers do.

  • Door, hatch & canopy sealing systems
  • Battery-enclosure & access-panel gaskets
  • Interior trim & molded plastic components
  • APQP-style launch discipline for rate ramp-up

General Aviation OEMs & Kit Builders

Piston singles, light twins, experimental and kit aircraft — we build to your print, in the quantities GA programs actually order.

  • Cabin door & window seals
  • Windshield & canopy trim profiles
  • Grommets, boots, bumpers & edge trim
  • Low-to-mid volume runs with consistent quality

Aviation Suppliers & Distributors

Parts and pilot-supply distributors need a reliable domestic source for rubber and plastic components their customers reorder year after year.

  • Private-label & build-to-print manufacturing
  • Extruded seal profiles by the foot or cut-to-length
  • Custom packaging, labeling & kitting
  • U.S.-made, Ohio-shipped inventory programs
Products & Capabilities

FAQ

Common questions from aviation buyers

Is Green Tokai AS9100 certified?

We currently hold IATF 16949:2016, ISO 9001:2015 and ISO 14001:2015 certifications, and AS9100 certification is in progress with a target of January 1, 2027. We're happy to begin quoting, prototyping and qualification work now so your program is ready when certification is complete.

Do you design parts, or build to print?

We build to print. Green Tokai does not hold product-design responsibility — your designs, specifications and drawings remain yours. Our engineering team provides manufacturability feedback, tooling design and process development to help your design succeed in production.

What volumes do you support?

Our roots are in high-volume automotive production, but we work with aviation programs at every stage — from prototype and low-rate initial production through full-rate manufacturing. Tell us your annual volumes and we'll recommend the right approach.

Can you supply distributors and parts retailers?

Yes. We offer build-to-print and private-label manufacturing, custom packaging and labeling, and cut-to-length or bulk extruded profiles for aviation supply companies.

What does KAI Innovations offer aviation businesses?

KAI Innovations is Green Tokai's innovation group. It provides fast-turn 3D-printed prototypes and shop fixtures, plus custom printing and branded apparel for flight schools, FBOs, clubs and aviation events.

What should I send to get a quote?

A drawing or 3D model, material and performance requirements, estimated annual volume and target timing. Samples of existing parts are also welcome.
