Advanced Manufacturing Capabilities for eFoil Projects
We don’t just build products—we deliver scalable, high-performance custom hydrofoil surfboard solutions for brands and businesses.
Aerospace Carbon Fiber: Light & Strong
T700 aerospace-grade carbon fiber with advanced molding and autoclave curing ensures precise construction. Delivers over 40% higher stiffness and torsional strength, while maintaining a lightweight 18–25 kg build for high-speed performance and durability.
Full Anti-Corrosion & Sealed Protection
SUS316L stainless steel combined with co-cured construction provides superior corrosion resistance. IP68 full-body sealing prevents water ingress, ensuring long-term durability and reliable performance in harsh marine environments.
Integrated Reinforcement for Stability
One-piece co-cured reinforcement structure enhances rigidity and torsional strength. Reinforced mast connection and impact-resistant design improve stability and safety, ensuring consistent performance during high-speed riding.
Challenges in eFoil Manufacturing & How We Solve Them
Brands entering the hydrofoil surfboard market often face technical and production barriers. We eliminate these risks.
Poor Corrosion Resistance — Metal Components Rust and Fall Off
Metal components on traditional hydrofoils are highly susceptible to oxidation and corrosion in saltwater and salt-spray environments, leading to part detachment and significantly shortened product lifespan.
Our Solution: All metal components are made from SUS316L ultra-low carbon austenitic stainless steel, offering superior corrosion resistance compared to standard 316/304 grades. Every metal part features an anti-loosening, anti-rotation design and is co-cured directly with the carbon fiber body during molding — fundamentally eliminating the risk of detachment.
Poor Sealing on Split-Shell Structures — Prone to Cracking and Water Ingress
Traditional top-and-bottom shell assemblies suffer from low sealing reliability. Over time, joints crack and allow water penetration, causing the internal core to absorb water, reducing buoyancy, accelerating structural corrosion, and creating serious safety hazards.
Our Solution: The upper and lower shells are simultaneously laid up and pre-formed as a single unit, then co-cured in one integrated process — completely eliminating seam leakage. The internal core material has been independently improved to achieve an extremely low water absorption rate, ensuring sufficient buoyancy is maintained even in the extreme scenario of a structural breach, preventing the board from sinking.
Insufficient Internal Structural Strength — Prone to Deformation Under High-Speed Impact
Traditional boards lack effective internal reinforcement, making them vulnerable to deformation during high-speed riding and wave impacts. The mast connection area in particular is a structural weak point, posing a risk of fracture and serious safety concerns.
Our Solution: Internal reinforcing ribs are integrated into the board and co-cured with the main body as a single piece, delivering superior torsional rigidity and stiffness compared to post-bonded alternatives — with no risk of delamination or adhesive failure. The mast and hydrofoil wings are manufactured using a composite molding process with internal core filling, and the mast connection area receives dedicated reinforcement design, ensuring structural safety and stability under the most demanding riding conditions.
Advanced Carbon Fiber Manufacturing Processes
JCsportline integrates a full in-house carbon fiber production system, enabling precise process selection for different components such as boards, masts, and hydrofoils. By combining autoclave and compression molding technologies with customizable core materials (PMI / PU / EVA / EPS), each product is optimized for its specific performance, weight, and structural requirements.
Autoclave Process (Autoclave Vacuum Curing)
- 3K carbon fiber texture is vivid, clean, and free from distortion
- Supports hollow structures with integrated reinforcement ribs
- Allows ultra-light or no core material for maximum weight reduction
- Ideal for high-end products with premium appearance and strict lightweight demands
- More complex layup and manufacturing process
Compression Molding (PMC)
- Core material must be integrated during preforming
- Limited in creating hollow structures with reinforcement ribs
- Requires core materials with sufficient strength and thermal compatibility
- Suitable for non-3K or non-exposed carbon fiber finishes
- Higher production efficiency, stable process, and better cost control
From Concept to Delivery
We provide a complete development workflow for your custom hydrofoil surfboard project.
Design
Hydrofoil geometry is developed using structural simulation and FEA stress analysis. SUS316L insert positions, foil-mast interface tolerances, and winglet profiles are finalized in 3D CAD before a single gram of carbon is cut. Tooling design is completed in-house for full dimensional control.
Craftsmanship
Aerospace T700 dry carbon prepreg is precision-cut in our constant-temperature, humidity-controlled layup room. Multi-directional ply orientation is hand-laid and laser-verified. Internal support frames are co-positioned before autoclave sealing. Cure cycle: 120°C, high-pressure vacuum — one shot, no secondary bonding.
Quality
Every board exits the autoclave and enters a multi-stage inspection line: airtightness, hydrostatic pressure, drop impact, repetitive load cycling, and 48h submersion. Three-dimensional scanning confirms foil-wing geometry accuracy. Pass rate ≥ 98%. Each unit receives a unique serial code with full data traceability.
Delivery
Smart production scheduling ensures batch on-time delivery with rush options available. Custom protective packaging prevents transit damage. Full documentation package included: BoM, process parameters, test reports, and installation/maintenance manual.

Frequently Asked Questions
Common Technical Questions About Carbon Fiber Mouse Development and Manufacturing
We’re Here to Help
T700 is an aerospace-grade carbon fiber material whose strength and modulus are far higher than those of ordinary civilian carbon fiber. Combined with a vacuum autoclave process, the finished product achieves significantly improved stiffness, fatigue resistance, and durability, while also being lighter in weight. Its service life is more than 30% longer than that of ordinary carbon fiber hydrofoils, making it suitable for high-intensity and high-wear water conditions.
Our full dry carbon construction features a one-piece molded structure without adhesive bonding, ensuring higher structural integrity, lighter weight, and complete water sealing. It offers excellent resistance to saltwater corrosion and aging, with a lifespan 3–5 times longer than traditional hydrofoils. Additionally, it delivers superior control, responsiveness, and hydrodynamic efficiency, providing a clear performance advantage.
We address marine durability through both material selection and advanced manufacturing processes. All metal components are made from SUS316L ultra-low carbon austenitic stainless steel, offering significantly better corrosion resistance than standard 316 or 304 stainless steel in saltwater environments. Furthermore, metal parts are co-cured with the carbon structure, and the upper and lower shells are integrally co-molded. Combined with IP68-rated full-body waterproofing, this eliminates risks such as component detachment, structural cracking, or water ingress—ensuring reliable long-term use in seawater.
We offer flexible customization based on client requirements. Key parameters include board length (180–220 cm), mast height, hydrofoil wingspan, and core material options (PMI, PU, EVA, EPS, etc.). In addition, clients can choose personalized finishes, including custom paint schemes and various carbon fiber weave surface patterns, enabling full alignment with brand and performance needs.
No. The internal structure uses an upgraded low water-absorption core material with an absorption rate below 0.5%. Even in the case of extreme outer shell damage, the core provides sufficient emergency buoyancy to prevent sinking, ensuring enhanced safety during water use.
Maintenance is simple and does not require specialized procedures. For long-term use, we recommend:
- Rinsing the unit with fresh water after saltwater use and drying the surface to prevent salt residue buildup.
- Periodically checking metal connections for tightness, as well as monitoring remote controller battery and signal status.
- Storing the product in a dry, ventilated environment away from direct sunlight and heavy pressure during long-term storage.
No professional servicing is required, significantly reducing maintenance costs—making it especially suitable for commercial applications such as rentals, resorts, and water sports clubs.
