Background

At present, in aquaculture, a culture net box is generally required to be supported by a buoy. People hope that the floating ball has large buoyancy and long service life, and the swing and shaking amplitude of the part under the sea surface is small, so that the floating ball structure is continuously improved by the technical personnel in the field to obtain good use effect. The floating ball developed by the inventor, namely the novel floating ball in the Chinese patent CN207400181U, the light foaming body filled in the floating body is used as an inner core, so that the floating body can be effectively prevented from sinking caused by seawater infiltration when the floating body cracks, tears or is broken. However, when the light foam filling type buoy is manufactured by using the existing processing method, the buoy shell is heated too high in the foaming process of the filler, so that the buoy can be shrunk and damaged, the buoy quality is influenced, the processing efficiency is low, the processing cost is high, and the popularization and the utilization of products are not facilitated.
