Filament Winding Process:

  • Traditional filament process
    The resin-impregnated glass fiber roving is wound on a rotating mandrel under a certain tension according to a certain rule and then cured into a product.
  • Continuous filament process
    By the continuous back and forth circulation operation of the steel belt, the processes of filament winding, compounding, sanding, and curing are continuously completed on the inner core mold that moves forward, and finally, it is cut into products.
