Double Color Mold for Central Control Storage Box Lid - China Suppliers and Factory Solutions
This mold is specifically designed for two-color injection molding processes. Both the cavity and core material are made of P20 pre-hardened plastic mold steel, ensuring high wear resistance and dimensional stability. The mold base is made of 45# carbon structural steel, balancing strength and cost-effectiveness. The ejector system integrates a pin-type ejector and ejector plate for efficient demolding. The hot runner system, combined with a standard side gate, optimizes the injection process. The dual water-cooling channel design improves cooling efficiency and shortens the production cycle. The mold supports simultaneous molding of two grooves (right groove + left groove) to meet the needs of complex structures.
Material Properties
P20 steel is pre-hardened (HRC 28-32), which is wear-resistant and corrosion-resistant, and suitable for high-precision injection molding; 45# steel mold base is heat-treated, with excellent comprehensive mechanical properties.
Structural Design
The two-color injection cavity and core material are integrated to reduce splicing errors; the hot runner system reduces scrap rate; and the side gate structure simplifies mold complexity.
Cooling Efficiency
Dual water cooling channels provide uniform heat dissipation, preventing localized overheating and deformation, and improving the surface finish of the product.
Compatibility
Supports simultaneous molding of multiple tooth sockets, adapts to left/right tooth structures, and has strong scalability.
Automotive Electronics
Interior components such as the central control storage box cover require two-color injection molding and high dimensional precision.
Home Appliance Manufacturing
Complex structural shells, such as two-color buttons and decorative panels, require wear resistance and deformation resistance.
Industrial Components
Small, precision parts that require efficient demolding and mass production, such as connectors and snap-fit products.

Q What materials are used for the cavity and core of this two-color injection mold?Both the cavity and core are made of P20 pre-hardened plastic mold steel (HRC 28-32), which offers excellent wear resistance, corrosion resistance, and dimensional stability for high-precision injection molding applications.
-
Q What type of gate system does this mold use?This mold uses a hot runner system combined with a standard side gate. This combination optimizes the injection process, reduces material waste, and lowers the overall scrap rate during production.
-
Q How does the cooling system work in this mold?The mold features a dual water-cooling channel design that provides uniform heat dissipation across the mold surface. This prevents localized overheating and deformation, improves surface finish quality, and significantly shortens the production cycle.
-
Q What industries are best suited for this two-color injection mold?This mold is ideal for automotive electronics (e.g., central control storage box covers), home appliance manufacturing (e.g., two-color buttons and decorative panels), and industrial component production (e.g., precision connectors and snap-fit parts).
-
Q How many cavities does this mold support, and what configurations are available?The mold supports 2 cavities simultaneously — a right groove and a left groove — allowing for efficient production of mirrored or paired components in a single molding cycle. It also supports simultaneous molding of multiple tooth sockets with strong scalability.
-
Q What ejection system is used, and how does it ensure efficient demolding?The mold integrates a pin-type ejector combined with an ejector plate system. This dual-mechanism approach ensures smooth and reliable part release, minimizing the risk of part damage during demolding and supporting high-volume production efficiency.
