Double Color Mold for Bottom Plate Sink - High-Precision Manufacturing 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.

Why is P20 steel used for the cavity and core material?
P20 steel is chosen for its outstanding combination of high hardness, wear resistance, and corrosion resistance. These properties ensure that the mold cavity and core maintain dimensional accuracy and surface quality over extended production runs, significantly extending mold service life.
What is the advantage of the double toothed (right tooth + left tooth) cavity design?
The double toothed design allows the mold to produce both right-hand and left-hand socket components simultaneously in a single production cycle. This bidirectional connection capability reduces tooling costs and efficiently meets complex assembly requirements for piping and structural applications.
How does the hot runner system benefit the injection molding process?
The hot runner system keeps the plastic material in a molten state within the runner channels, eliminating cold runner waste and reducing material costs. It also improves cycle times, ensures consistent filling of cavities, and delivers better surface quality on finished products compared to conventional cold runner systems.
What industries are best suited for this mold?
This mold is well suited for the automotive, home appliance, commercial kitchen equipment, and bathroom facility industries. It is particularly effective for producing base plate water tanks, customized sink products, decorative components, and any parts requiring two-tone or multi-material combinations.
Can this mold support large-scale or continuous production?
Yes. The water-cooling system significantly shortens each production cycle by accelerating heat dissipation, making the mold ideal for high-volume continuous manufacturing. The optimized ejection system and durable P20 steel construction further minimize downtime and maintenance requirements during large-scale operations.
Is this mold suitable for small and medium-sized enterprises?
Absolutely. The integration of the hot runner system minimizes material waste, which directly lowers production costs per unit — a significant benefit for cost-sensitive SMEs. The mold's versatile design also allows quick adaptation to different product specifications, making it a flexible and economical tooling solution for businesses of all scales.
