China Double Color Mold for Bottom Plate Sink - High Precision Plastic Injection Molding Suppliers & Factory
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.
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.
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 mold?Both the cavity and core are made from P20 steel, known for its high hardness, superior wear resistance, and excellent corrosion resistance. This material significantly extends the overall service life of the mold under demanding production conditions.
-
What ejection system does this mold use?The mold uses a pin-type ejector combined with an ejector plate. This system ensures rapid and uniform demolding, effectively reducing the risk of product deformation during the ejection process.
-
How does the cooling system work, and what are its benefits?The mold employs a water-cooling design that circulates cooling water through internal channels. This accelerates the cooling speed, shortens production cycles, and ensures a consistent and high-quality surface finish on finished products — particularly advantageous in high-temperature or continuous operation environments.
-
What industries or applications is this mold suitable for?This mold is suitable for a wide range of applications, including automotive and home appliance manufacturing, commercial kitchen equipment, bathroom facilities, and decorative components. It is especially effective for products requiring complex connections, two-tone effects, or large-scale mass production.
-
What gate system is used, and why is a hot runner system included?The mold features both a hot runner system and a standard side gate. The hot runner system minimizes material waste by keeping the runner material molten between cycles, while the standard side gate ensures a smooth and consistent injection molding process — making it ideal for cost-sensitive small and medium-sized enterprises aiming to improve production efficiency.
-
Can this mold support two-color or multi-material production?Yes. The two-cavity design (right + left) supports two-color molds and multi-material combinations. This allows manufacturers to produce components with diverse color combinations or material properties in a single molding cycle, greatly enriching product design possibilities and meeting complex assembly requirements.
