China Suppliers Factory for Double Color Mold of Central Control Storage Box Lid - Precision Injection Molding
Product Overview
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.
Product Features
🛠️ 1. 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.
📐 2. 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.
❄️ 3. Cooling efficiency
Dual water cooling channels provide uniform heat dissipation, preventing localized overheating and deformation, and improving the surface finish of the product.
🔄 4. Compatibility
Supports simultaneous molding of multiple tooth sockets, adapts to left/right tooth structures, and has strong scalability.
Applicable Scenarios
