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 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, toughness, and machinability, making it ideal for high-precision injection molds used in automotive interior part production.
This mold achieves tolerances up to ±0.001mm, ensuring consistent dimensional accuracy across all production batches — a critical requirement for automotive-grade interior components.
Yes. Thanks to the modular design with sliding partition adjustments, a single mold can accommodate multiple product specifications. This significantly reduces mold change costs and downtime during production transitions.
The dual ejection mechanism — combining a right tooth and left tooth socket design — minimizes the risk of parts sticking to the mold. This reduces reliance on release agents, improves product yield, and contributes to a more environmentally friendly manufacturing process.
The mold uses a hot runner system combined with a normal side gate for precise material flow control. The cooling system is water-based, which accelerates the molding cycle and supports high-volume industrial production.
Absolutely. The combination of an efficient water-cooling system, optimized demolding mechanism, and 2-cavity configuration (right + left) makes this mold highly suitable for large-scale industrial production, significantly increasing output while reducing per-unit costs.
