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

-
Q What material is used for the cavity and core of this automotive storage box mold?
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 parts production.
-
Q What is the dimensional tolerance achievable with this injection mold?
This mold can achieve tolerances up to ±0.001mm, ensuring high dimensional consistency across large production runs. This level of precision is critical for automotive interior parts that require tight fitting and structural integrity.
-
Q Can one mold produce storage boxes of different sizes or configurations?
Yes. The modular design with a sliding partition mold allows flexible adjustment of the internal structure, enabling a single mold to accommodate multiple product specifications. This significantly reduces tooling costs and accelerates response to design changes.
-
Q How does the dual ejection mechanism improve production quality?
The dual ejection mechanism — comprising both a right tooth and a left tooth socket — minimizes the risk of mold sticking during demolding. It reduces dependency on release agents, which improves product yield, surface quality, and overall environmental performance of the production process.
-
Q What cooling method is used, and how does it affect production efficiency?
A water-cooling system is integrated into the mold design. This accelerates heat dissipation during the molding cycle, shortens cycle times, and makes the mold well-suited for high-volume industrial production while maintaining consistent part quality.
-
Q What types of automotive applications is this mold suitable for?
This mold is primarily designed for producing automotive interior storage components such as center console bases, door storage compartments, and multi-functional storage boxes with internal compartments. It meets industry requirements for high strength, wear resistance, lightweight construction, and environmental standards.
