Product Description

SUNMORE Factory Custom 7000L Rotomolded HDPE Water Tank Steel Mould

Professional heavy-duty rotational mould designed for one-piece rotomolding of 7000L large-capacity HDPE water storage tanks. Constructed from high-quality thick carbon steel for exceptional structural strength, heat resistance, and long service life.

Common Production Challenges

Poor structural strength leading to mould deformation and dimensional errors
Uneven heating causing inconsistent wall thickness and leakage risks
Unreasonable split structure increasing demoulding difficulty
Rapid wear and corrosion in high-volume production

Engineering Solutions

High-quality thick carbon steel material for structural rigidity and heat resistance
Optimized internal rib design for uniform heat distribution and consistent wall thickness
Scientific split structure with heavy-duty quick-release clamps for efficient operation
Professional anti-rust surface treatment for enhanced durability

Technical Specifications

Material	Heavy Duty Thick Carbon Steel
Processing Technology	CNC Cutting + Full Welding + Reinforced Ribs + Anti-rust Coating
Capacity	7000L (Customizable for other volumes)
Structure	Split mould with reinforced frame and quick-lock clamps

Applications

Industrial water supply, domestic drinking water storage, agricultural irrigation, rainwater collection, and other scenarios requiring large-volume water storage solutions.

Selection Guidance

Choose this steel mould when: You need mass production of 7000L HDPE water tanks, require high structural strength for continuous production, or your products demand high pressure resistance and durability.

Consider alternatives when: You require small-batch trial production or custom special-shaped tanks (aluminum moulds available), or need different volume capacities (custom moulds available for 1000L-20000L).
