  • Publication number: 20030141628
    Abstract: A molding method for protective equipment includes seven steps. A first step is to prepare a mold consisting of an upper and a lower mold respectively provided with a mold hole. A second step is to heat the mold to a preset first temperature. A third step is to place a plastic plate and a foam member in the mold. A fourth step is to move the upper mold nearer to the lower mold, and then close up the upper mold on the lower mold in a preset time for the two materials to melt. A fifth step is to heat the mold to a second temperature higher than the first temperature so that the outer surface of the two materials may melt. A sixth step is to cool the mold to a preset temperature to let the two materials cool to form a shape. The seventh step is to open the mold and take out a finished product.

  • Patent number: 6348167
    Abstract: A method for making a surfboard includes six steps of processes. The first step is to prepare and cut plastic plate material into a panel. The second step is to place it in a mold to hotly press to let the panel foam half. The third step is to take the half-foamed prototype out of the mold to let it continue to foam to expand. The fourth step is to place the fully foamed prototype in a baking device to heat it into an almost completed surfboard. The fifth step is to place it in a cooling mold to cool and harden to become a finished surfboard. The sixth step is to take the finished surfboard out of the cooling mold. Thus the method can shorten the time for making a surfboard and save material waste.
