Injection-moulded HDPE buoys engineered for long-line mussel farming. Two halves joined by hot-plate welding — no gas port, no foam fill, watertight to 30 m submersion. The standard Ø 500 × 1,200 mm body delivers 235 L of buoyancy at 25 kg. Extendable to project-specific lengths by hot-plate welding.
3D MODEL
Sheltered bays and coastal sites where the long-line stays at the surface or just below it. The standard Ø 500 × 1,200 buoy supports the cultivation rope and growing biomass through the full grow-out cycle; integral handles speed up rope work for the deck crew.
Wave-exposed sites where the long-line is sunk below the active wave zone. The injection-moulded body holds pressure to 30 m without deformation — no foam absorption, no gas-port leakage, buoyancy is preserved over the full service life.
For projects with heavy biomass, deep deployments or specific buoy spacing, the standard cylinder is extended by hot-plate welding. Buoyancy capacity and total length are dimensioned to site data; the same material integrity carries through to the extended body.
The mussel buoy is injection-moulded as two separate halves and joined by hot-plate welding into a single sealed vessel. The design has no gas filling port and uses no EPS or polyurethane fill, so the buoy does not absorb water over its service life.
The standard model is Ø 500 mm × 1,200 mm, 25 kg, with 235 L of buoyancy. Wall thickness is held to a minimum of 12 mm across all cross-sections — injection pressure makes this consistency achievable, eliminating the wall-thinning typical of rotomoulded floats. Internal cross-ribs distribute hydrostatic pressure, allowing the body to operate submerged to 30 m.
Integral top and bottom handles support rope tightening and loosening directly, with no auxiliary fittings. When project-specific length or buoyancy is required, the standard cylinder is extended by the same hot-plate welding method — material and joint integrity carry through to the extended body.
