Engineered Products for Demanding Applications
Sealing solutions and specialized components
Sealicone manufactures sealing systems, injection-molded plastic components, engineered assemblies and technical textile products. Each solution is designed to meet demanding industrial requirements for precision, strength and durability.
Aerospace Sealing
(wings, doors, landing gear, cargo holds, radomes…)
These sealing systems are mainly manufactured from silicone reinforced with different textiles to provide properties such as fire/smoke/toxicity resistance, tear resistance, abrasion resistance and contaminant resistance.
Silicone offers a very wide operating temperature range, typically from -55°C to +250°C, making it particularly suitable for aerospace sealing applications.
Hydrogen Sealing
(fuel cells, electrolyzers)
Sealicone has industrial equipment capable of manufacturing very thin sealing components with tolerances around 0.03 mm. The process is suitable for serial production and for materials specifically selected for hydrogen sealing applications.
Plastic Components
(single-material or bi-material injection molding)
Our production equipment includes modern electric injection presses. Our capabilities also include specialized processes such as blow molding for complex hollow components. Controlled-environment production areas support applications in sectors such as medical, food and advanced industry.
Metal Components
(sheet metal, tube forming, springs, injection and thermoforming molds, cutting and assembly fixtures…)
A broad range of production capabilities enables us to select the process best suited to the product and required volumes.
Our equipment includes high-speed machining centers, CNC machining tables, press brakes, CNC tube bending, laser cutting, welding, forming and paint facilities. These capabilities support prototypes, one-off parts, serial production, assembly fixtures, inspection fixtures and tooling for injection molding, thermoforming and thermocompression.
Technical Textiles
(webbing, bungee cords, braids, ropes, nets…)
Our production expertise covers wide and narrow weaving, knitting and braiding, using industrial methods developed over many years.
Technical textile products are used across many sectors:
- Consumer applications including elastic straps, cords and nets.
- Luxury applications including specialized tapes and ribbons.
- Defense applications including parachute and airdrop webbing.
- Transport applications including load-restraint webbing.
Textile Manufacturing
A dedicated manufacturing team integrates these products into complete assemblies such as harnesses, bags, protective equipment and seats.
Product access
Our web catalogue provides detailed access to our capabilities and product examples. Each product family can be adapted to the specific requirements of your project.
2 operating modes
Build to Print or Build to Spec
We are both a designer and a manufacturer.
We can manufacture standard or custom products from your drawings, or develop a specific solution from your technical requirements.
Build to Print: we manufacture components to your approved drawings and specifications.
Build to Spec: we develop solutions against your technical requirements and provide the applicable documentation for review and qualification.

Training
Sealing Design Training for Engineering Teams
We also help engineering teams develop their own sealing expertise.
Sealicone offers training for your teams on sealing-system design rules. This helps engineers account for sealing constraints early in the development process and optimize both design and performance.
A sealing solution is the result of both a functional specification and its operating environment. Sealing constraints are often considered too late, which can lead to complex, heavy or inefficient solutions and require costly changes to surrounding structures.
Training your teams in sealing-system design helps build awareness of these constraints from the earliest development stages.
It also enables customers to build and retain internal sealing know-how through structured experience and best-practice sharing.
