Double Color Mold for Bottom Plate Sink - High-Precision Molding from China Suppliers 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.

QWhat 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 extended mold life and consistent dimensional accuracy over long-term production runs.
QWhat ejection system does this mold use?
This mold employs a pin-type ejector working in combination with an ejector plate. This design achieves rapid and uniform demolding, effectively reducing the risk of product deformation during the ejection process.
QHow does the cooling system work and why is it important?
The mold uses a water-cooling system that accelerates the cooling speed of molded parts. This significantly shortens the production cycle, improves overall output efficiency, and ensures a high-quality surface finish on finished products.
QWhat industries or applications is this mold best suited for?
This mold is suitable for a wide range of applications including automotive and home appliance manufacturing, commercial kitchen equipment, bathroom sink production, and any scenario requiring complex two-tone or multi-material designs. It is ideal for both industrial-scale and SME production environments.
QWhat gate system is used, and how does it reduce production costs?
The mold uses a combination of a hot runner system and a standard side gate. The hot runner system minimizes material waste by keeping the runner molten, while the standard side gate ensures a smooth and consistent injection process, lowering overall material and operational costs.
QDoes the mold support two-color or multi-material production?
Yes. The mold features a double toothed design with two cavities (right tooth + left tooth), enabling bidirectional connection. Combined with two-color mold capability, it supports multiple material or color combinations in a single production cycle, enriching product design possibilities and meeting complex assembly requirements.
