How it’s Made: Surfboard
A surfboard is used in the sport of surfing. A typical surfboard is about 18-24 inches (46-61 cm) wide, 72-120 inches (183-305 cm) long, and several inches thick. It has a lightweight, buoyant core covered with a hard shell. In use, the surfer lays face down on the surfboard and paddles out into the ocean to the point where waves are beginning to rise.
1. Shaping the blank
To get it started, the white dense foam made of polyurethane is cut to shape using a CNC machine. The rough sandpaper is then carved on the sides or rails, eliminating any ridges left by the CNC cutter. Hand shape after cnc cut
By forming the outer shell of the surfboard, the laminating resin is spreadover fiberglass cloth. The polyester resin creates a chemical reaction, providing the material the slightly tacky and rubbery. This process gives the surfboard an added level of strength and wear resistance when facing those deep waves.
3. Placing the Inlays(design)
Inlays are printed onto a silk/polymer mesh fabric with UV resistant inks and then placed onto the board and the resin (used to harden the fabric) is squeegied over the top until it is soaked into the foam, which is an overnight process.
4. Sanding and Finishing
Finally, the board is carefully sanded using a power sander mainly for broad surfaces.
