Rotational Moulding Support Floating Cylinder Type EPS Foamed PE Buoy
DESCRIPTION:
Rotational moulding plastic buoy,
Inside filled with expanded polystyrene(EPS),
Outer shell is rotational polyethylene thickness 8-10mm,
Steel structure inserts, can be stainless steel or h.d.galvanized steel with eye rings or swivels at both end.
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.Rotational molding is a manufacturing process used to produce hollow plastic items such as buoys. It involves heating and rotating a mold, usually made of metal, while adding plastic resin. Rotation ensures that the resin evenly coats the inner surface of the mold, resulting in a seamless and uniform product. EPS (expanded polystyrene) foam is a commonly used material for rotational molding in buoy production.
EPS is lightweight, buoyant and has good insulating properties, making it suitable for buoy applications. It is also durable and resistant to damage from UV radiation and the marine environment. PE (polyethylene) is another material commonly used for rotational molding in buoy manufacturing. PE is a versatile lightweight plastic with excellent buoyancy, chemical resistance and durability. It is also resistant to UV radiation, impact and cracking, making it suitable for use in harsh marine conditions.
EPS foam and PE are combined in rotomolded buoys to create a product with excellent buoyancy, durability and resistance to natural damage. These buoys are commonly used in marine and aquaculture applications for tasks such as marking waterways, supporting fishing nets, or providing flotation for floating docks.

MANUFACTURING PROCESS:
Rotational moulding is a process of forming hollow plastic products. Firstly put the plastic power into the mold and 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, injection and blow molding processes, which are often used in plastic molding. The rotational moulding process is more suitable for the production of large, medium or complex plastic products. The products have almost no internal stress to ensure a very long service life.
