Double Color Mold for Bottom Plate Sink - High-Precision Molding by China Suppliers and Factory
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.

What material is used for the cavity and core of this injection mold?
Both the cavity and core are made of P20 steel, which offers high hardness, excellent wear resistance, and strong corrosion resistance. This ensures long mold life and consistent dimensional accuracy over extended production runs.
What type of gate system does this mold use?
This mold uses a combination of a hot runner system and a standard side gate. The hot runner system minimizes material waste and reduces cycle time, while the normal side gate ensures a smooth and reliable injection molding process.
How does the cooling system work in this mold?
The mold features a water-cooling design that rapidly dissipates heat after each injection cycle. This shortens the overall production cycle, maintains consistent product quality, and ensures excellent surface finish on finished parts.
Is this mold suitable for two-color or multi-material production?
Yes. The two-color mold design supports multiple material or color combinations in a single production cycle. This makes it ideal for products requiring dual-material functionality or decorative two-tone effects, such as kitchen utensils or automotive components.
What industries can benefit from this injection mold?
This mold is widely applicable across multiple industries, including automotive parts, home appliances, commercial kitchen equipment, and bathroom facilities. It is particularly suited for producing base plate water tanks, sink products, and components requiring high precision and durability.
How does the ejection system prevent product deformation during demolding?
The mold uses a pin-type ejector working in conjunction with an ejector plate. This combination distributes ejection force evenly across the part surface, enabling rapid and uniform demolding while significantly reducing the risk of warping or deformation in finished products.
