- Design for tight routing paths and confined spaces
- Pressure-rated and vacuum-rated constructions
- Specification of reinforcement materials (polyester, Nomex®, wire helix, etc.)
- Integration of specialist liners: Silgiene® and FKM/Viton Profuel
- CAD-based design and dimensional modelling
- Support with prototype development and validation
Hose Insert Design
Silflex creates custom inserts which perfectly match the silicone hose assemblies to enhance system durability, improve fluid flow and enhance the overall system performance.
- Custom metal, composite, or polymer insert design
- Smooth-bore, stepped, or profiled insert geometries
- Corrosion-resistant materials for marine and industrial environments
- Fuel- and oil-resistant designs for automotive, truck, bus, and off-highway applications
- Optimised design for pressure retention and mechanical stability
- Perfect integration with bespoke hose shapes
- Development of inserts for prototype or volume production
Hose Manufacture
Our manufacturing capabilities cover simple straight lengths through to complex assemblies with tight tolerances and specialist reinforcement.
- Mandrel-built hoses in a wide range of sizes
- Multiple reinforcement options (polyester, Nomex®, wire helix, glass-fibre braid)
- One-piece assemblies to eliminate joint failures
- Multi-layer hose construction for high-temperature or high-pressure environments
- Controlled curing and finishing processes for consistent wall thickness
- Convoluted and castellated options for increased flexibility
- Rapid prototyping and short lead times for custom builds
- Scalable production for OEM volumes
Tooling Manufacture
All our tooling is designed and manufactured in-house, giving us total control over accuracy, consistency, and quality of production.
- CAD-designed mandrels and tooling for consistent geometry
- Rapid prototype tooling for fast development cycles
- Tight-radius and complex multi-plane shapes
- Tooling solutions for multi-layer and high-temperature constructions
- Controlled tolerances for repeatable, high-volume manufacturing
- Cost-effective tooling options for OEM production
