All the lamination steps of the high density sandwich and then of the fiber are carried out under vacuum. The board is under strong pressure, from 2 to 4 tonnes depending on the stage, to ensure flawless bonding of the layers. With the use of drains we optimize the amount of resin on the board leaving only the optimum. Your board is light and super compact. A durable board made to handle all the stresses of a board’s life, its construction also offers a sound basis for any future repairs. So your board will stay like new for years or decades with proper maintenance. This durability will make a lot of people happy from one owner to the next, and avoids polluting with “disposable” boards.
To implement this very complex technology, we need time. A board without a full sandwich is built in 6 to 8 hours. GONG full sandwich boards take 12 to 14 hours of work. You understand that all these steps lengthen the production circuit and are therefore a monumental investment in quality.
