High-Strength Mould for Pre-Retention Tank from China Suppliers - Durable Factory Solutions for Irrigation & Engineering
Product Overview
The mould for pre-retention tank is a mold product specifically designed for rapid and efficient construction. It uses P20 steel (cavity and core material) and 45# steel (mold base) as its core materials. Through a modular design of inner and outer mold sections, screw assembly, and a water-cooling system, it ensures the mold remains deformation-free during long-term use. Equipped with a pin-type ejector, two threaded slots (right thread + left thread), and a standard side door, it supports rapid demolding and efficient production, significantly shortening the construction period. It is particularly suitable for projects with high requirements for construction speed and terrain adaptability.
Product Features
High-strength Materials
◎ The cavity and core material are made of P20 steel, and the mold base is made of 45# steel, which is pressure-resistant, wear-resistant, and has high stability in long-term use.
Modular Structure
◎ The inner and outer molds are designed in sections and assembled with screws, which facilitates demolding and transportation and improves construction efficiency.
High-efficiency Cooling System
◎ Integrated water cooling device to accelerate concrete solidification and shorten production cycle.
Quick Demolding Design
◎ Equipped with a pin ejector and ejector plate, combined with two toothed grooves (right tooth + left tooth) to achieve quick demolding.
Terrain Adaptability
◎ The modular design supports deployment in complex environments such as slopes and sandy areas without the need for large-scale earthwork.
Use Cases
Agricultural Irrigation
Drip irrigation for orchards in hilly and mountainous areas, and water-saving systems for high-standard farmland to achieve gravity irrigation.

Frequently Asked Questions
The cavity and core are made from P20 steel for superior wear and pressure resistance, while the mold base is constructed from 45# steel, ensuring structural rigidity and long-term dimensional stability during high-volume production.
The inner and outer mold sections are designed in separate modules assembled with screws. This approach simplifies on-site installation, reduces transportation difficulty, speeds up demolding, and allows the mold to be quickly relocated to new construction sites.
The mould features an integrated water-cooling system. Coolant is circulated through channels within the mold to rapidly dissipate heat, accelerate concrete solidification, and shorten each production cycle — significantly boosting daily output capacity.
The mould is equipped with a pin ejector and an ejector plate working in conjunction. Combined with two threaded toothed grooves — one right-thread and one left-thread — the system enables fast, controlled ejection of finished parts, minimizing cycle time and reducing manual labor requirements.
Yes. The modular structure is specifically designed for terrain adaptability. It can be deployed on slopes, sandy terrain, and other complex environments without the need for large-scale earthworks or specialized foundation preparation, making it ideal for remote or challenging project sites.
This mould is widely used across agricultural irrigation systems, rural drinking water projects, emergency flood and drought relief operations, municipal sponge city rainwater management, ecological landscape water features, and construction site water storage — wherever fast and reliable concrete tank production is required.
