Sealicone was founded in 2014 following the meeting between an aerospace sealing expert and an industrial entrepreneur from northern France seeking to expand his group into the aerospace sector.
Sealicone is involved at every stage of project development, with the conviction that early involvement delivers long-term benefits through better control of quality, schedules and costs.
Sealicone has implemented a quality system focused on thorough risk management at every stage of each project.
The company is certified to ISO 9001 and EN 9100.
What we manufacture
As both a designer and manufacturer, we can meet your requirements through a broad range of standard products manufactured to drawing, or through specific developments tailored to your technical specifications.
Operating modes:
- Build to print: you provide the drawings and we manufacture the products you have designed.
- Build to spec: you provide your technical specification and we propose suitable solutions, including the qualification documentation required to validate product compliance.
Our areas of expertise:
Aerospace sealing: wings, doors, landing gear, cargo holds, radomes and more.
These seals are mainly manufactured from silicone reinforced with various textiles to provide resistance to fire, abrasion and contaminants.
Silicone is particularly well suited to aerospace sealing thanks to its wide operating temperature range, from -55°C to +250°C.Hydrogen sealing: fuel cells and electrolyzers.
Our industrial equipment can manufacture extremely thin sealing components with tolerances of approximately 0.03 mm.Plastic components: single-material or bi-material injection molding.
Our modern equipment supports specialized processes such as blow molding for complex containers and parts.Metal components: sheet metal work, tube forming, springs, injection molds, fixtures and more.
Our equipment includes machining centers, laser cutting, forming and other advanced processes.Technical textile products: webbing, bungee cords, braids, ropes and nets.
We master weaving, knitting and braiding processes for demanding sectors including luxury goods, defense and transport.
What we offer
Expertise:
Sealicone supports customers from the earliest project milestones to validate designs and optimize performance. We work on-site or remotely at key stages to help ensure project success.
Training:
We provide training to help your teams understand the design rules for sealing systems. This allows specific constraints to be anticipated from the earliest phases and helps avoid additional cost or delays caused by late design changes.
What we offer
Founded in 2014, Sealicone grew from the meeting of an aerospace sealing specialist and an industrial entrepreneur from northern France looking to expand into this demanding sector. We become involved early in each project to ensure strong control of quality, schedules and costs.
Our quality system is certified to ISO 9001 and EN 9100, with risk management integrated throughout the development process. This rigor enables us to meet the demanding requirements of aerospace, defense and space applications.
Design and manufacturing: our core expertise
As a designer and manufacturer, we can work from existing drawings (build to print) or from technical specifications (build to spec). In the latter case, we propose suitable solutions and provide qualification documentation to validate the compliance of each developed product.

Hydrogen sealing: fuel cells and electrolyzers.
Manufacture of very thin seals with tolerances of approximately 0.03 mm.
Plastic components: single-material or bi-material injection molding.
Blow-molding capability for complex geometries.
Metal components: sheet metal, tube forming, springs, injection molds and fixtures.
Machining centers, laser cutting, forming and related processes.
Technical textile products: webbing, bungee cords, braids, ropes and nets.
Weaving, knitting and braiding processes for luxury, defense and transport applications.
More than a manufacturer: a partner
Expertise: we support customers from the earliest project milestones to validate designs and optimize performance. Early involvement helps reduce additional costs and secure product quality.
Training: we train your teams in sealing-system design rules so that aerospace and other demanding constraints can be anticipated early, reducing delays and late-stage changes.
Over the years, Sealicone has become a trusted supplier of custom sealing solutions, from prototypes to serial production. Through collaboration and quality, we help customers address their most demanding technological challenges.
