China Storage Box Molds - Reliable Suppliers and Factory for Efficient Production and Custom Design
Product Overview
Mold for Storage Boxes are multi-functional molds specifically customized for injection/rotational molding processes. Using high-precision P20 steel as the core material, they integrate a high-efficiency cooling system and an intelligent ejection structure, enabling rapid mass production of standardized or personalized plastic storage boxes. Suitable for diverse scenarios such as automotive manufacturing, logistics warehousing, food and pharmaceuticals, electronic components, and industrial chemicals, their modular design flexibly matches single-cavity/multi-cavity production needs, significantly improving demolding efficiency and product stability. They meet special industry standards such as high durability, high hygiene, and anti-static properties, helping companies reduce costs and increase efficiency.
Product Features
1. Highly Durable Material
◎ Both the cavity and the core material are made of P20 steel, which combines wear resistance and corrosion resistance, extending the mold life.
2. Flexible Process Adaptation
◎ It supports multiple processes such as injection molding and rotational molding, and can produce single-cavity or multi-cavity molds to meet the needs of small-batch or large-scale production.
3. Customized Design
◎ Adjustable size, number of parting surfaces, and ejection method (such as integrated condenser tubes and electric telescopic rods) optimize demolding efficiency.
4. High-Efficiency Cooling System
◎ Built-in water-cooling channels shorten cooling time, improve production efficiency, and reduce energy consumption.
5. Precise Structural Configuration
◎ Equipped with a pin ejector, ejector plate, and double-tooth groove (right tooth + left tooth) design, it ensures precise and stable product demolding.

Conclusion
Frequently Asked Questions
Both the cavity and the core are made of high-precision P20 steel, which offers excellent wear resistance and corrosion resistance, ensuring long-term mold durability and consistent product quality across extended production runs.
Yes. The mold is designed to be compatible with multiple manufacturing processes, including both injection molding and rotational molding, making it highly flexible for various production requirements and output volumes.
Absolutely. The mold supports full customization of dimensions, parting surface count, cavity number (single or multi-cavity), and ejection methods. This allows the mold to be tailored precisely for your specific product requirements and production scale.
These molds are designed for a wide range of industries, including automotive manufacturing, logistics and warehousing, food and pharmaceuticals, electronics, and industrial manufacturing. Special versions meeting anti-static, high-hygiene, or heavy-duty corrosion resistance standards are also available.
The mold features built-in water-cooling channels that circulate cooling water through the mold during production. This significantly reduces the cooling cycle time, improves overall production efficiency, and helps lower energy consumption compared to conventional cooling methods.
The mold uses a combination of a pin ejector and an ejector plate, along with a double-tooth groove design (right tooth + left tooth). This configuration ensures precise, stable, and damage-free demolding of finished products, maintaining consistent dimensional accuracy and surface quality.
