High-Precision Plastic Mold for Central Control Storage Box Base - Top China Suppliers and Factory Solutions
Product Overview
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.
Product Features
◎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.

Frequently Asked Questions
-
Q What material is used for the cavity and core of this automotive storage box base mold?
Both the cavity and core are made from P20 steel, which offers excellent toughness, machinability, and wear resistance — making it ideal for producing high-precision automotive interior components at scale.
-
Q What dimensional tolerance can this injection mold achieve?
This mold achieves tolerances of up to ±0.001mm, ensuring exceptional dimensional consistency across all production batches. This level of precision is critical for automotive interior parts that require strict fit and finish standards.
-
Q How does the modular design benefit different product specifications?
The sliding partition mold design allows the internal structure to be flexibly adjusted, enabling a single mold to produce multiple product specifications. This significantly reduces tooling investment and allows manufacturers to respond rapidly to design changes.
-
Q What type of ejection system does this mold use, and what are its advantages?
The mold uses a combined pin ejector and ejection plate system with a dual ejection mechanism (right tooth + left tooth socket). This design minimizes mold sticking, reduces the need for chemical release agents, and improves both production yield and environmental performance.
-
Q Is this mold suitable for large-scale mass production?
Yes. The mold features a water-cooling system that accelerates the molding cycle and a 2-cavity layout (right + left), combined with a hot runner system and normal side gate. Together, these features significantly increase production capacity and reduce per-unit costs, making it well-suited for large-scale industrial manufacturing.
-
Q What types of automotive applications is this mold designed for?
This mold is specifically designed for automotive interior applications, including center consoles, door storage compartments, and multi-functional compartmentalized storage boxes. It meets strict automotive requirements for strength, wear resistance, lightweight construction, and environmental compliance.
