- Rotomoulded Chemical Tank Mould
Chemical storage tanks are critical components used across industries for the safe handling, storage, and transportation of various chemicals, acids, alkalis, and industrial liquids. These tanks must withstand harsh chemical reactions, environmental conditions, and mechanical stress while ensuring zero leakage and maximum safety.
With the shift from traditional metal tanks to advanced plastic solutions, rotomoulded chemical tanks have gained significant popularity due to their superior corrosion resistance, seamless construction, and long service life. These tanks are manufactured using rotational molding technology, which requires precision tooling known as Rotomoulded Chemical Tank Moulds.
These moulds are designed to produce strong, durable, and chemically resistant tanks with uniform wall thickness and integrated functional features. High-quality moulds ensure consistent production, enhanced safety, and optimal performance in demanding industrial environments.
Understanding Rotomoulded Chemical Tank Moulds
A rotomoulded chemical tank mould is a specially engineered metal mould used to manufacture plastic chemical storage tanks through the rotational molding process. These moulds define the tank’s shape, capacity, wall thickness, and structural features such as inlet/outlet provisions, reinforcement ribs, and mounting supports.
The mould design ensures seamless tank formation without joints or welds, which is essential for preventing chemical leakage and ensuring structural integrity. Advanced moulds also incorporate provisions for fittings such as flanges, lids, valves, and level indicators.
These moulds are typically manufactured using mild steel or aluminum, offering durability, efficient heat transfer, and long operational life. Proper mould design is essential for producing tanks that meet safety and industrial standards.

Working Principle
Chemical tanks are manufactured using the rotational molding process.
Material Loading
A precise amount of chemical-grade polyethylene powder is loaded into the mould.
Heating and Rotation
The mould is heated and rotated along two axes, allowing the material to melt and coat the inner surface.
Material Distribution
The molten plastic spreads evenly, forming a uniform tank structure.
Cooling Phase
The mould is cooled to solidify the tank.
This process ensures seamless, leak-proof, and highly durable chemical tanks.
