Sekisui Aerospace

What Sekisui Aerospace does

Sekisui Aerospace is a US-based Tier 1 aerospace manufacturer of advanced composite structures, systems, and engine components, headquartered in Renton, Washington and operating as a wholly-owned subsidiary of Japan's SEKISUI CHEMICAL CO., LTD. since November 2019 (acquired from Liberty Hall Capital Partners). The company runs three Centers of Excellence — Renton, WA (renovated and expanded for intelligent automation and rapid prototyping), Sumner, WA (composites manufacturing with RFID-enabled smart-factory deployment), and Orange City, IA (composites, NDT, and chemical processing) — totaling more than 500,000 square feet of manufacturing space, 50+ production lines, and 1,000+ employees.

Its core product portfolio spans aerospace structures (fuselage, wing, and interior composite components), systems, and engine components, manufactured using automated fiber placement, autoclave and out-of-autoclave processing, compression molding, bladder molding, and thermoplastics (including Continuous Compression Molding equipment acquired in November 2021). Proprietary technology includes the SITE (Software for Infrared Thermography Evaluation) for non-destructive testing of composite structures, an Xemelgo-deployed RFID tracking system that has reduced missing plaster molds from 600-800/month to fewer than 10, and a multi-phase Industry 4.0 buildout integrating with Epicor ERP and AI-powered dashboards. The company holds NADCAP (composites at all three sites plus NDT and chemical processing at Orange City), AS9100D, ISO 9001:2015, ITAR registration, and Boeing D6-51991 Digital Product Definition approval with eight Boeing common process certifications.

Sekisui Aerospace monetizes through long-term B2B contracts with major aerospace OEMs and Tier 1 suppliers (Boeing, Spirit AeroSystems) via a direct enterprise field-sales motion with dedicated program management teams. Pricing is not publicly disclosed and is quote-based on custom composite components and assemblies. The company markets at industry events such as Farnborough International Airshow 2026, and is recognized as a Spirit AeroSystems 2021 Top Supplier. It is led by President and CEO Daniele Cagnatel, who has held the role since January 2018.

• SEKISUI CHEMICAL CO., LTDcoreStrategic or Co-development Partner · 22 November 2019SEKISUI CHEMICAL CO., LTD completed the acquisition of AIM Aerospace (renamed Sekisui Aerospace) on November 22, 2019. The acquisition brought stability and has enabled investments in new technology and automation. Sekisui Aerospace's parent company has been recognized as one of the Global 100 Most Sustainable Corporations in the World for six consecutive years.
• XemelgocoreTechnology or Integration · 1 January 2019Xemelgo, a software startup co-founded in 2018 by former Hitachi employees, partnered with Sekisui Aerospace to implement RFID tracking technology across the aerospace supplier's composites manufacturing facilities in Washington state. The three-phase deployment, spanning from 2019 to April 2024, reduced missing plaster molds from 600-800 per month to fewer than 10, cut staff needed to locate parts from 15 to three at Sumner facility, and increased production by 3 percent. Xemelgo is expanding the system to Sekisui's Renton facility while developing AI-powered dashboards and integrating with ERP systems like Epicor.
