Product Description

                                                                             Aquaculture Fish Farming PE Buoys
                                                                                         ---OEM & ODM---

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.

Strong, foam filled and unsinkable buoys, enable its to be well used for mooring fish cages and other aquaculture applications. 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.

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.

Indented area for retro-reflective tape inhibits sliding and loss of reflective material.

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.
