Custom Heavy-Duty Fabricated Steel Rotational Mold with Reinforcement Frame for Large Water Tanks & Chemical Storage Vessels OEM/ODM

Constructed from high-grade structural steel plate using precision laser cutting, CNC bending, and expert MIG/TIG welding, this sheet metal rotomolding mold features a heavy-gauge outer reinforcement frame. This structural design ensures exceptional cavity rigidity, absorbing multi-axis rotational torque and preventing wall deformation during high-temperature oven heating.

Featuring precision-machined parting flanges with silicone gasket grooves and quick-release perimeter toggle clamps, this steel mold delivers leak-proof sealing and minimal flash.

• Lower tooling costs — steel molds offer reduced initial investment compared to aluminum molds.
• Shorter lead times — faster production turnaround for large-capacity hollow products.
• Superior rigidity — heavy-gauge reinforcement frame resists rotational torque and thermal deformation.
• Leak-proof sealing — precision-machined parting flanges with silicone gasket grooves.
• Minimal flash — quick-release perimeter toggle clamps ensure consistent mold closure.

We offer complete turnkey OEM/ODM engineering based on your 2D/3D CAD drawings, delivering custom rotational mold solutions tailored to your specific product requirements.
