What Aero-Plastics does

Aero-Plastics Inc. is a US-based, AS9100:2016 Rev D-certified contract manufacturer of precision plastic components, operating a single facility in Renton, Washington, since 1945. The company produces machined nonmetallic and injection molded parts using high-performance polymers and engineered resins (PEEK, Ultem, Vespel, Torlon, Delrin) and commodity resins, with injection molding press capacity ranging from 40 to 660 tons and five-axis CNC machining for complex geometries. Differentiated capabilities include specialized Vespel polyimide machining across SP-1 through ST2030 grades, a Rapid Response service offering two-week turnaround, and a proprietary "Dependometer" internal performance measurement tool paired with a cradle-to-grave documentation system providing full traceability.

The company serves three regulated verticals: aerospace (AS9100-certified, Boeing and GE Aviation qualified, ITAR registered, DPD/MBD certified), medical device (ISO 13485:2016 compliant, FDA-approved materials), and high-performance commercial sectors (energy, telecommunications, transportation). Aero-Plastics has received the Boeing Performance Excellence Award every year since its inception in 2007 — a distinction held by only five companies globally — and additional Boeing Supplier of the Year (2000, 2013), Boeing President's Award (1993), and GE Aviation Commitment to Excellence (2009) recognitions.

Commercially, Aero-Plastics operates enterprise field sales with quote-based pricing, a website-driven request-for-quote funnel with one-business-day response, and direct engagement by technical sales management. Value-added services (assembly, painting, ultrasonic welding, custom packaging) extend into turnkey solutions. The firm has been a wholly-owned subsidiary of Sweden's Trelleborg Group since 2022, integrated into Trelleborg's aerospace engineered-polymers offering.
