High-Precision Plastic Mold for Central Control Storage Box Base | China Suppliers & Factory
This mold produces automotive storage box bases using injection molding, with its core function being to ensure high precision and batch production stability. It utilizes P20 steel (cavity and core material) and a 45# mold base, combined with a pin-type ejector/ejector plate demolding system to optimize the production process. Modular design (such as adjustable partitions) supports the production of multiple specifications, reducing mold change costs; a double ejection mechanism reduces the risk of mold sticking; and a water-cooling system improves cooling efficiency, meeting the requirements of automotive interior parts for strength, lightweight design, and environmental friendliness.
High Precision and Durability
◎ High-precision replication of complex mesh structures, with tolerances up to ±0.001mm, ensuring dimensional consistency and strength. Detail is handled through mechanisms such as angled pull blocks and side sliders, achieving efficient demolding.
Modular Design
◎ The sliding partition mold allows for flexible adjustment of the internal structure, and one mold can accommodate multiple product specifications.
Optimized Demolding System
◎ The dual ejection mechanism (right tooth + left tooth socket) reduces reliance on release agents, improving yield and environmental friendliness.
High-Efficiency Cooling
◎ The water-cooling system accelerates the molding cycle and is suitable for large-scale industrial production.
Automobile Manufacturing
Producing interior parts such as center consoles and door storage compartments, which must meet the requirements of high strength, wear resistance and lightweight.
Customized Production
Suitable for multi-functional storage boxes with compartments, modular design allows for rapid response to design changes.
Mass Production
The injection molding process, combined with an efficient demolding and cooling system, significantly increases production capacity and reduces unit cost.

Both the cavity and core are made from P20 steel, which offers excellent hardness, wear resistance, and polishability — making it ideal for high-precision injection molds used in automotive interior components.
This mold achieves tolerances up to ±0.001mm, enabling high-precision replication of complex structures including mesh patterns, ensuring consistent dimensional accuracy across all production batches.
Yes. The modular design features a sliding partition mold that allows flexible adjustment of the internal structure. This means a single mold can accommodate multiple product specifications, significantly reducing tooling costs and changeover time.
The dual ejection mechanism — consisting of both a right tooth and a left tooth socket configuration — minimizes dependence on release agents. This design significantly reduces the risk of mold sticking while improving both production yield and environmental performance.
The mold uses a hot runner system combined with a normal side gate for precise material flow control. The water-cooling system is integrated to accelerate the molding cycle, making it well-suited for large-scale industrial production environments.
This mold is primarily designed for the automotive manufacturing industry, producing interior parts such as center consoles and door storage compartments. It is also suitable for customized multi-compartment storage boxes and any mass production scenario requiring high strength, wear resistance, and lightweight design.
