High-Precision Plastic Mold for Central Control Storage Box Base - China Suppliers and 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 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.
◎ The sliding partition mold allows for flexible adjustment of the internal structure, and one mold can accommodate multiple product specifications.
◎ The dual ejection mechanism (right tooth + left tooth socket) reduces reliance on release agents, improving yield and environmental friendliness.
◎ The water-cooling system accelerates the molding cycle and is suitable for large-scale industrial production.
Producing interior parts such as center consoles and door storage compartments, which must meet the requirements of high strength, wear resistance and lightweight.
Suitable for multi-functional storage boxes with compartments, modular design allows for rapid response to design changes.
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, machinability, and wear resistance — ideal for high-volume automotive injection molding applications.
This mold achieves tolerances up to ±0.001mm, ensuring exceptional dimensional consistency across all production batches — a critical requirement for automotive interior components.
Yes. Thanks to the modular design with a sliding partition system, the internal structure can be flexibly adjusted. A single mold can accommodate multiple product specifications, significantly reducing mold change costs and lead times.
The mold uses a dual ejection mechanism — combining a pin ejector and ejection plate — along with a right tooth and left tooth socket configuration. This design minimizes reliance on release agents, improves the yield rate, and reduces the risk of mold sticking during production.
The mold uses a water-cooling system that accelerates the molding cycle by rapidly reducing part temperature after injection. This shortens cycle times and makes the mold 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, door storage compartments, and multi-functional storage boxes. It is also suitable for customized production runs and high-volume mass production scenarios where consistent quality and cost efficiency are required.
