The foundation of a high-performance surfboard lies in its materials and the precision with which they are crafted. At JCSPORTLINE, we take inspiration from aerospace engineering to bring you a surfboard that combines strength, flexibility, and lightweight performance like no other. Let’s dive into the two critical steps that define our material stage: intelligent prepreg cutting and PU core casting.
Intelligent Prepreg Cutting—Precision Down to 0.2 mm
When it comes to crafting a surfboard that performs flawlessly under pressure, the devil is in the details—or more specifically, in the carbon fiber layup. JCSPORTLINE imports aviation-grade uni-directional and twill prepregs, materials renowned for their exceptional strength-to-weight ratio. These prepregs are not just any carbon fiber; they’re engineered to provide directional stiffness and controlled flex, making them ideal for surfboards that need to handle both power and finesse.

What sets us apart is our use of AI-guided cutters to map your board’s load paths with unparalleled precision. Each piece of prepreg is cut with edge accuracy down to ±0.2mm, ensuring that every fiber aligns perfectly with the intended stress points of the board. This meticulous process eliminates excess resin and unnecessary weight, giving you a lay-up that places carbon exactly where it’s needed. The result? A surfboard that feels lighter, responds faster, and delivers consistent performance wave after wave.
For surfers who demand the best, this technology ensures that no two boards are alike unless they’re meant to be. Whether you’re carving sharp turns or gliding smoothly across the face of a wave, the intelligent layup guarantees optimal energy transfer and responsiveness.
PU Core Cast in One Shot—Zero Void, Zero Waste
The heart of every surfboard is its core, and at JCSPORTLINE, we’ve revolutionized the way PU foam cores are made. Using CNC-machined aluminum molds, we cast the PU blank in a single shot, completing the process in just 90 seconds. This method ensures a density tolerance of ±2%, delivering identical buoyancy and flex characteristics in every board we produce.

Traditional hand-shaped blanks often suffer from inconsistencies, leading to what surfers call the “golden board” lottery—where only a few boards out of a batch truly perform as expected. With our closed-mold PU casting process, that uncertainty is eliminated. Every board you pick up will feel the same underfoot, whether you’re riding your first wave of the day or your last.
This level of consistency isn’t just about performance—it’s also about sustainability. By minimizing voids and waste during production, we reduce material scrap and environmental impact. It’s a win-win for surfers and the planet alike.
