China Double Color Mold for Bottom Plate Sink - High Precision Suppliers & Factory Solutions
1 Materials and Structures
◎ Cavity and core material: Made of P20 steel, which has high hardness, wear resistance and corrosion resistance, extending the mold life.
◎ Mold base material: 45# steel provides high-strength support, ensuring the mold remains stable during high-pressure injection molding.
◎ Double toothed design: Two toothed sockets (right tooth + left tooth) support bidirectional connection to meet complex assembly requirements.
2 Functional System
◎ Pop-out system: The pin-type ejector works in conjunction with the ejector plate to achieve rapid and uniform demolding and reduce product deformation.
◎ Gate design: The hot runner system reduces material waste, while the standard side gate ensures a smooth injection molding process and improves production efficiency.
◎ Cooling system: Water cooling design accelerates cooling speed, shortens production cycle, and ensures the surface finish of products.
3 Advantages
◎ Precision and durability: P20 steel material ensures dimensional stability over long-term use.
◎ Multifunctionality: Two-color molds support multiple materials or color combinations, enriching product design.
◎ High-efficiency production: Optimized systems reduce downtime and are suitable for large-scale manufacturing.

Both the cavity and core are made of P20 steel, which offers high hardness, excellent wear resistance, and strong corrosion resistance. This ensures long-term dimensional stability and extended mold service life.
The mold uses a pin-type ejector in conjunction with an ejector plate. This combination achieves rapid and uniform demolding, effectively minimizing product deformation during the release process.
This mold employs a water-cooling system that accelerates the cooling speed of each production cycle. It shortens the overall production cycle, maintains consistent surface finish of products, and is particularly suitable for high-temperature continuous operation environments.
This mold features a hot runner system combined with a standard side gate. The hot runner system significantly reduces material waste, while the side gate ensures a smooth and stable injection molding process — improving production efficiency and reducing per-unit material costs.
This mold is suitable for a wide range of industries, including automotive parts, home appliance components, commercial kitchen equipment, and bathroom facilities. It is especially ideal for producing base plate water tanks, sink products, and decorative components requiring complex connections or two-tone color effects.
Yes. This mold is designed for two-color molding, supporting the combination of multiple materials or color schemes within a single production cycle. The double toothed socket design (right tooth + left tooth) enables bidirectional connection, making it highly suitable for complex product design and large-scale manufacturing needs.
