Industry Pain Points
Designed to match you, wherever you dive
JCSPORTLINE engineers every fin around you — with customizable width and foot shape tailored for global body profiles.
Your performance begins with carbon
JCSPORTLINE uses T700-grade carbon fiber to give your fins lighter weight, stronger power, and unmatched propulsion efficiency.
Your difference starts with JCSPORTLINE.
We empower your brand through OEM/ODM solutions and transparent testing data that turn performance into credibility.
Engineering & Design
- T700 Prepreg Carbon Fiber
- Finite Element Analysis
- 3D CAD Modeling
T700 Prepreg Carbon Fiber
→ High strength-to-weight ratio with controlled lamination accuracy.
Finite Element Analysis
→ Simulate stress distribution at different kicking angles to optimize the lamination structure.
3D CAD Modeling
→ Precisely control the foot pocket curvature and fin surface profile to ensure alignment with the ankle’s motion path.
Engineering & Quality
Where precision engineering meets uncompromising quality assurance.
Manufacturing Process
JCSPORTLINE crafts your fins with precision — from CNC-milled P20 steel molds to T700 carbon layers built for strength and flexibility.
Each fin is molded at 150 °C with real-time monitoring and CNC-polished to perfection, giving you smooth edges, consistent performance, and professional propulsion.
Testing & Certification
Your fins are developed and validated under ISO 20653 and ASTM D3039 standards — tested for 1200 MPa tensile strength, 80 GPa flexural modulus, and over 100,000 fatigue cycles.
They withstand 48 hours of salt-spray and five −20 °C to 60 °C thermal shocks with zero delamination.
In real-world dives, professional freedivers reached 124 m depth with 27% higher propulsion efficiency — proving your fins deliver unmatched stability and power underwater.
Smart Manufacturing
Your fins are produced through a fully digital and intelligent manufacturing system.
High-speed automated cutters shape each carbon layer at 1000 mm/s, while smart molding units monitor temperature and pressure in real time to keep every cycle precise.
All data — from layup order to curing curve — is tracked in the MES system and secured with blockchain traceability, giving you total transparency from raw fiber to finished fin.
