Custom Fabricated Steel Rotational Mold for Marine Pontoons, Modular Dock Floats & Buoy Hydrodynamic Bodies OEM/ODM Tooling

Designed for marine infrastructure, floating docks, jet ski ramps, and navigation buoys, our Custom Fabricated Steel Rotational Mold provides a heavy-duty, impact-resistant tooling solution for manufacturing seamless PE marine pontoons and modular dock floats.

Crafted from heavy-duty structural steel sheets, the mold cavity accurately replicates complex hydrodynamic waterlines, tie-down grooves, and interlocking corner mounting slots. All internal welds are meticulously polished to ensure clean surface finishes and effortless demolding of thick-walled, foam-fillable marine plastic shells.

Supported by a custom-welded outer steel truss frame with integrated crane lifting lugs, this mold easily handles multi-axis rotation and heavy resin loads without flexing. Multi-point quick-release toggle clamps along the parting line guarantee uniform sealing pressure and leak-proof edges. We deliver full turnkey OEM/ODM custom tooling manufacturing tailored precisely to your marine CAD drawings.
