Rotational PE Buoy with EPS Foamed
Waysail rotational moulding plastic mooring buoys filled with closed cell EPS/PU foam, buoy shell made by marine corrosion resistant polyethylene, a central tubular steel frame, forming a high quality moooring buoy with excellent performance and lower cost. Our mooring buoys are rapidly replacing the traditional steel mooring buoys. This is due to their low maintenance costs, excellent waterproofing, impact resistance, long service life, easy construction, easy to handle and repair.
Material Specifications:
Outer Shell: Rotational Moulded Polyethylene, Thickness 8-10mm.
Foam: Expanded Polystyrene(EPS)/ PU.
Steel Structure: Inserts are made with a stainless steel or hot dipped galvanized steel pipe with lifting eyes welded.
Colour: Yellow/Orange
Our company promises that 100% of our products use original raw materials, all the waste materials produced in the production process will be destroyed through formal channels or resold to the recycling middleman.
Plastic Buoy Features & Benefits:
Highest quality UV stabilized seamless one-piece construction with uniform wall thickness ensures a robust life expectancy to 15+ years.
Large diameter load plates secured to the shell for maximum load disbursement.
Refined EPS foaming process with over 20 years of experience significantly reduced risk of sinking and environmental contamination.
Swivel eyes prevent twisting and moderate strain on the tackle.
The robust, seamless outer shell made from high quality polyethylene(PE) by the rotational molding process. The seamless construction eliminates weak points, enabling the buoy with highly resistance to leaks, cracks, and the it's UV-Stability. The expanded polystyrene(EPS)foam is a critical structural and safety component, since EPS foam core is inherently buoyant and will not become waterlogged even the outer PE shell is compromised, which ensure that the mooring system retains flotation. Also, the EPS foam core provides continuous internal support to PE shell, which reduces the risk of the plastic deformation under the continuous down pull in mooring system.

Application:
Offshore vessel mooring
Remote mooring of vessel
Fish Farming Cage Support
Additional mooring support for large vessel
When the buoy is used in aquaculture mooring system, the buoys are fitted with a high quality galvanized steel rod and swivel. Cage buoys are to be used to suspend a submerged cage at its design depth. The primary function is to support the cage net buoyancy load in operational (submerged) condition. A secondary function will be to be used as a temporary mooring buoy occasionally when workers are on-site.
Manufacturing Technique:
Rotational moulding is a process of forming hollow plastic products. Firstly put the plastic power into the moldand then heated and rotated along two vertical axes. The powder in the mold is melted and adhered onto the mold inner surface, then cooling down the mold and take out the product when it reaches a correct temperature.
Compare to the extrusion, injuection and blow molding processes, which are often used in plastic molding. The rotatinal moulding process is more suitable for the production of large, medium or complext plastic products. The products have almost no internal stress to ensure a very long service life.
