Product Description

Custom Rotomolding Steel Mould for HDPE Water Tank & Large Capacity Water Tower

Heavy-duty rotational mould independently designed and manufactured for one-piece rotomolding of HDPE large-capacity water storage tanks, water towers, and industrial water containers. Constructed from high-quality thick carbon steel for excellent structural strength, heat resistance, and long service life.

Key Problems Solved

Structural Strength & Deformation Prevention

High-grade thick carbon steel with reinforced ribs ensures stable structure and prevents deformation during repeated high-temperature cycles, maintaining precise dimensional accuracy.

Uniform Heat Distribution

Optimized internal design provides consistent heating, eliminating weak points and leakage risks while ensuring uniform tank wall thickness and pressure resistance.

Efficient Demoulding Process

Split-type structure with heavy-duty quick-release clamps enables fast assembly, disassembly, and demoulding, significantly improving production efficiency.

Extended Service Life

Professional anti-rust and anti-wear treatment reduces maintenance frequency and extends mould lifespan for high-volume production.

Technical Specifications

Material	High-Quality Thick Carbon Steel
Processing Technology	CNC Cutting + Full Welding + Reinforced Ribs + Anti-Rust & Anti-Wear Treatment
Customization	Supports OEM/ODM customization of tank capacity, shape, connection ports, and structural details according to customer specifications
Structure	Split mould with reinforced frame, quick-lock clamps, and standard rotomoulding equipment interface

Applications

Rotomolding production of HDPE large-capacity water tanks, water towers, and industrial water containers for industrial water supply, domestic drinking water storage, agricultural irrigation, rainwater collection, aquaculture, and other scenarios requiring large-volume water storage.

Selection Guide

Choose This Mould When:

Mass production of high-quality large-capacity HDPE water tanks and water towers
Require mould with high structural strength and long service life for continuous production
Products for industrial/agricultural use demand high pressure resistance and durability

Consider Other Options When:

Small-batch trial production or special-shaped tank designs (aluminum moulds available for faster prototyping)
Other volume requirements (custom mould solutions available for 1000L-20000L water tanks)

Frequently Asked Questions

Can you customize moulds for different water tank capacities and shapes?

Yes, we provide full OEM/ODM customization services, supporting moulds for water tanks from 1000L to 20000L in various shapes (cylindrical, square, tapered) according to your requirements.

What are the advantages of steel mould for large-capacity water tank production?

Steel mould has high structural strength, good pressure resistance and cost-effectiveness, making it more suitable for mass production of large-volume tanks. It maintains stable performance under long-term high-temperature use and has a longer service life.

Can the mould produce water tanks with different connection ports or accessories?

Yes, we can design the mould according to your requirements, including reserved ports for inlets, outlets, overflow valves, manholes and other accessories.

What is the service life of this steel mould?

With proper maintenance, the mould can support tens of thousands of rotomoulding cycles, ensuring long-term stable production of high-quality water tanks.

We purchase various specifications from 0.5T to 10T cylindrical horizontal tanks to install on farm transport trucks for liquid fertilizer and pesticide delivery. Premium LLDPE material is corrosion resistant to farm chemicals, no liquid spillage even on bumpy country roads.

We ordered a large batch of 5T horizontal roto tanks for urban construction project water supply. Thickened LLDPE material ensures outstanding pressure resistance, no bulging after long-time full-load water storage. Horizontal design saves construction space and speeds up installation work.

These 3000L vehicle-mounted cylindrical tanks work perfectly for our farm irrigation liquid transport. Uniform wall thickness via rotational molding prevents cracking under long-term continuous use. We will reorder more for our newly added engineering fleets.
