China Plastic Mold for Central Control Storage Box Base - High Precision 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.

-
What material is used for the cavity and core of the automotive storage box base mold?
Both the cavity and core are made of P20 steel, which offers excellent toughness, wear resistance, and polishability — making it well-suited for high-precision automotive interior part production.
-
What dimensional tolerance can this injection mold achieve?
This mold achieves tolerances up to ±0.001mm, ensuring highly consistent dimensions across every production batch — a critical requirement for automotive interior components.
-
Can this mold support multiple product specifications?
Yes. Thanks to the modular design with a sliding partition system, a single mold can accommodate multiple product specifications. This significantly reduces mold changeover costs and allows rapid adaptation to design changes.
-
How does the ejection system reduce the risk of mold sticking?
The dual ejection mechanism — combining right tooth and left tooth socket configurations — distributes ejection forces evenly, minimizing mold sticking risks and reducing the need for release agents, which also improves environmental performance.
-
What type of gate system does this mold use?
This mold uses a combination of a hot runner system and a normal side gate. The hot runner minimizes material waste and improves cycle time, while the side gate ensures smooth material flow and surface finish quality.
-
Is this mold suitable for large-scale industrial production?
Absolutely. The water-cooling system efficiently accelerates the molding cycle, and the 2-cavity design (right + left) doubles output per cycle. Combined with stable demolding and precise gating, this mold is fully optimized for high-volume automotive parts manufacturing.
