Quick photo of the vacuum bag process , the black plates with the paper tape around has the kiteboard inside. The plates are 5mm thick and are 152x45 , we use 2 plates , one on top of the kiteboard and one below.
The black plates are to keep the lamination on the kiteboard perfectly flat whilst being held on the mold , the plates are waxed to avoid bonding to the actual kiteboard or to the mold. The process removes all the air from the laminations.
The mold as seen from the end has the kiteboard positioned to the far left, this is too maximize the hook type concave , for a rider with less weight the kiteboard can be positioned to the right molding less concave on to the actual kiteboard . A rider with less weight does not need so much lift generated by a larger concave.
The molds are created on our cnc machine , the mold in the photo is 150 x 54. The vacumm bag is the pink flexible type used widely in F1.
