SUNMORE OEM ODM Rotomolded Spherical Water Tower Mold
This large-scale high-precision rotational mould is independently designed and manufactured by SUNMORE factory for one-piece rotomolding of HDPE spherical water towers and storage tanks. Engineered for domestic water supply, industrial water storage, agricultural irrigation, and environmental projects.
Key Manufacturing Advantages
Uniform Wall Thickness Control
Conventional moulds often suffer from uneven heating in large spherical structures, resulting in inconsistent wall thickness and poor pressure resistance. Our reinforced and evenly heated design ensures uniform heat transfer and consistent wall thickness, significantly improving structural strength and pressure-bearing capacity.
Precision Spherical Contours
Ordinary moulds struggle to reproduce smooth spherical surfaces and functional openings, leading to burrs, seams, or difficult demoulding. Our split-type spherical mould with precision positioning and quick-release clamps ensures smooth, seamless tank surfaces and easy, damage-free demoulding.
Structural Rigidity & Stability
Large spherical moulds are prone to deformation under high-temperature and rotational forces. Our mould is reinforced with a sturdy frame and multi-point support, ensuring stable structure and consistent product quality even in long-term high-volume production.
Enhanced Corrosion Resistance
Without proper anti-corrosion treatment, moulds used for water tank production are easily corroded by steam and chemicals. Our mould undergoes professional anti-corrosion and anti-rust treatment, maintaining stable precision and smooth surfaces for tens of thousands of production cycles.

Frequently Asked Questions
Can you customize the capacity and size of the spherical water tank?
Yes, we provide full OEM/ODM customization services, supporting various capacities, diameters, wall thicknesses, and functional configurations to meet your specific storage needs.
What are the advantages of spherical water tanks compared to other shapes?
Spherical tanks have uniform stress distribution, high pressure resistance, and better space efficiency. The seamless rotomolded construction also eliminates weak points, making them more durable and leak-proof.
Can the mould produce tanks with custom openings or accessories?
Yes, we can integrate custom inlet/outlet ports, manholes, mounting brackets, and other features into the mould according to your requirements.
How long is the service life of this mould?
With proper maintenance, including regular cleaning and anti-rust treatment, the mould can maintain high precision for tens of thousands of rotomoulding cycles.
