Double Color Mold for Bottom Plate Sink - High Precision from China Suppliers & Factory with Efficient Demolding System
◎ 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.
◎ 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.
◎ 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.
Suitable for the production of base plate water tanks in industries such as automobiles and home appliances, meeting the requirements of high precision and high strength.
It performs exceptionally well in scenarios requiring complex connections or two-tone effects, such as multifunctional kitchen utensils or decorative components.
In the injection molding workshop, this mold can quickly adapt to different production needs and improve overall production capacity.
The water-cooling design is particularly suitable for high-temperature environments, ensuring stability during continuous operation.
It can be used for mass production of customized sink products, such as commercial kitchen equipment or bathroom facilities.
Hot runner systems are suitable for cost-sensitive small and medium-sized enterprises, reducing material waste.
| Cavity material | P20 steel |
| Core material | P20 steel |
| Mould base material | 45# |
| Ejection system | Pin ejector and ejection plate |
| Number of cavity | 2 cavities (right + left) |
| Gate | Hot runner system + Normal side gate |
| Cooling system | By water |
Both the cavity and core are made from P20 steel, which offers excellent hardness, wear resistance, and corrosion resistance — significantly extending the overall mold service life.
The mold uses a pin-type ejector system combined with an ejector plate, enabling rapid and uniform demolding while minimizing product deformation during the injection molding process.
This mold uses a water-cooling design that accelerates the cooling rate of molded parts, shortens the production cycle, and helps maintain consistent surface finish quality across all produced parts.
Yes. The two-color mold design supports multiple material or color combinations within a single production cycle, enabling richer product aesthetics and enhanced design flexibility for complex parts.
This mold is widely applicable across automotive, home appliance, commercial kitchen, and bathroom fixture industries. It is particularly effective for producing base plate water tanks, sink components, and decorative or functional multi-tone parts.
The mold features a hot runner system paired with a standard side gate. The hot runner minimizes material waste and reduces costs, while the standard side gate ensures smooth, consistent flow during injection — making it ideal for both high-volume and cost-sensitive production environments.
