Surfboard fin and manufacturing technology thereof

Abstract

The invention relates to the technical field of surfboard fins, in particular to a surfboard fin and a manufacturing technology thereof. The manufacturing technology comprises the following steps of A, cutting a calico, a honeycomb screen cloth and glass into the shape of a fin; B, opening a mold, sequentially laying the cut glass, the cut calico, the cut honeycomb screen cloth into the mold, arranging a plurality of convex blocks on the inner side face of the top of the mold, and closing and screwing down the mold; C, injecting resin into the mold, baking and forming the resin, and conducting cooling to obtain a fin, wherein a plurality of grooves are formed in one side of the fin; D, opening the mold, taking out the formed and cooled fin, and sanding and polishing the fin to obtain the surfboard fin. The obtained surfboard fin is low in cost, easy and convenient to use, low in weight, high in buoyancy force and capable of reducing resistance, improving lift force and improving the whole performance.

Description

Technical field [0001] The invention relates to the technical field of surfboard fins, in particular to a surfboard fin and a manufacturing process thereof. Background technique [0002] Surfing is a water activity that tests the sense of balance and instant reaction of the body. It relies on the power of the waves to move forward and the buoyancy of the surfboard on the waves. Therefore, the surfboard has become a necessity for this sport. [0003] Fin-shaped rudder is an indispensable main unit of a surfboard. If there is no fin-shaped rudder, the surfboard will lose its balance, direction and floating effect. The material and weight of the fin-shaped rudder will also affect the surfboard. The float and operation stability. At present, in order to make it light and economical, the industry has eliminated wood and switched to fin-shaped rudders made of resin and glass fiber. However, although this design can save production costs and reduce weight, it still has considerable weig...

AI Technical Summary

Problems solved by technology

However, although this design can save production cost and weight, it still has a considerable weight. When surfing, because people stand on the surfboard, because of the weight of the fin-shaped rudder, the rear end of the surfboard is easy to get off first. Shen, and can not make the surfer to maintain a longer surfing time on the waves, and this also makes the surfboard can not really meet the positive meaning of light weight, floating; improve
