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.

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, wear resistance, and machinability — making it ideal for high-volume automotive injection molds requiring tight tolerances and long service life.
-
Q What level of dimensional tolerance can this mold achieve?
This mold achieves tolerances up to ±0.001mm through high-precision machining. Complex mesh structures and fine details are reproduced accurately using angled pull blocks and side slider mechanisms, ensuring consistent part quality across every production run.
-
Q Can this mold produce storage boxes of different sizes or internal configurations?
Yes. The mold features a modular design with a sliding partition system, allowing flexible adjustment of the internal compartment structure. A single mold can accommodate multiple product specifications, significantly reducing the cost and time associated with mold changes.
-
Q How does the dual ejection mechanism improve production efficiency and quality?
The dual ejection system — comprising a right tooth ejector and left tooth socket — ensures uniform force distribution during part release. This minimizes the risk of mold sticking and part deformation, reduces dependency on chemical release agents, and improves both the yield rate and environmental performance of the production process.
-
Q What type of gate system does this mold use, and why?
The mold uses a combination of a hot runner system and a normal side gate. The hot runner system reduces material waste and cycle time, while the side gate provides reliable flow control for consistent part filling — making this configuration well-suited for mass production of automotive interior components.
-
Q Is this mold suitable for large-scale industrial automotive production?
Absolutely. The mold is engineered with a water-cooling system that accelerates the molding cycle, enabling high-throughput production. Combined with its 2-cavity configuration, efficient demolding system, and durable P20 steel construction, it is fully optimized for large-scale industrial manufacturing of automotive interior parts such as center consoles and door storage compartments.
