Rotomolded Polyethylene(PE) Buoy Conical Type
Our produced PE buoy is roto-molded polyethylene outer shell, EPS or PU foamed, hot dipped galvanized steel structure in the middle with strong terminating discs at the both ends of buoy. PE Buoy is commonly used in aquaculture fish farming mooring system, shellfish mooring, seaweed cultivation mooring grid with its characteristics of strong and light weight.
1. Material Specifications:
Outer Shell: Roto molded hard PE shell, thickness 8-10mm.
Foam: Expanded Polystyrene(EPS) or PU.
Stell Structure: Inserts steel struture is hot-dipped galvanized, with round discs at the both ends.
Color: Yellow/Green/As per client's requirement
2. Buoy Features & Benefits:
4Durability & Impact Resistance: Crafted through rotational molding, these buoys are seamless and hollow, ensuring exceptional strength and resistance to physical impacts in harsh marine environments.
Corrosion & Chemical Resistance: Made from high-density polyethylene (HDPE), they withstand saltwater, oils, and chemicals, outperforming metal alternatives prone to rust.
UV Stabilization: Treated with UV inhibitors to prevent degradation, ensuring long-term performance under constant sun exposure.
Lightweight & Easy Handling: Easier to install and deploy compared to metal buoys, reducing labor and logistical costs.
Seamless Design: Eliminates weak points, preventing leaks and water absorption for consistent buoyancy.
Customizable Options: Available in various sizes, colors, and shapes (spherical, cylindrical) with integrated attachment points for ropes/chains.
Temperature Resilience: Maintains structural integrity in diverse climates, from freezing waters to tropical heat.
Eco-Friendly: Recyclable material aligns with sustainable aquaculture practices.
3. Applications in Aquaculture:
Mooring Systems: Anchor fish cages, net pens, and floating platforms, ensuring stability in strong currents or tides.
Marker Buoys: Delineate farm boundaries or sensitive zones with high-visibility designs.
Support for Floating Infrastructure: Provide buoyancy for walkways, feeding platforms, and harvest stations.
Shellfish & Seaweed Farming: Used in oyster, mussel, or algae cultivation systems for flotation and organization.
Load Distribution: Work with chains, ropes, and anchors to evenly distribute tension, preventing system submergence.
Anti-Fouling Solutions: Smooth PE surface resists barnacle and algae buildup, reducing maintenance (optional coatings available).

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.
