China Storage Box Mold Suppliers - High-Quality Factory Solutions for Efficient Plastic Container Production
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
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.
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.
Customized Design
◎ Adjustable size, number of parting surfaces, and ejection method (such as integrated condenser tubes and electric telescopic rods) optimize demolding efficiency.
High-Efficiency Cooling System
◎ Built-in water-cooling channels shorten cooling time, improve production efficiency, and reduce energy consumption.
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.
