Frequently Asked Questions
Q1
What material is used for the cavity and core of this mold, and why?
+
Both the cavity and core are made from P20 steel. This material is chosen for its excellent combination of high hardness, wear resistance, and corrosion resistance. These properties significantly extend mold service life and maintain dimensional accuracy over long production runs, making it ideal for demanding injection molding applications.
Q2
What does the "double toothed design" mean, and what are its benefits?
+
The double toothed design refers to two toothed sockets built into the mold — one right tooth and one left tooth. This configuration supports bidirectional connection, allowing the mold to meet complex assembly requirements. It is especially useful for producing components that need to be joined or mated in multiple orientations, improving versatility across different product designs.
Q3
How does the cooling system work, and why is water cooling important?
+
This mold uses a water-cooling system that circulates water through internal channels to rapidly extract heat from the mold after each injection cycle. Water cooling is critical because it directly shortens the production cycle, increases output efficiency, and ensures the surface finish and dimensional accuracy of finished products. It is also particularly well-suited for high-temperature or continuous-operation environments.
Q4
What is the difference between the hot runner system and the normal side gate used in this mold?
+
The hot runner system keeps plastic material in a molten state within the runner channels, eliminating runner waste and reducing material costs — making it cost-effective for high-volume production. The normal side gate, used alongside the hot runner, provides a straightforward and reliable injection point that ensures a smooth, controlled flow of material into the cavity, resulting in consistent part quality and high production efficiency.
Q5
What types of products or industries is this mold best suited for?
+
This mold is highly versatile. It is well-suited for producing base plate water tanks, sink components, and structural parts used in the automotive, home appliance, and commercial kitchen industries. It also supports the production of two-tone or multi-material decorative components, making it a strong choice for businesses needing both functional precision and aesthetic flexibility in their injection molded parts.
Q6
Is this mold suitable for small and medium-sized enterprises (SMEs)?
+
Yes. The inclusion of a hot runner gate system makes this mold particularly cost-effective for SMEs, as it significantly reduces material waste compared to traditional cold runner systems. The optimized ejection and cooling systems also minimize downtime and maintenance requirements, lowering the overall cost of operation. Whether for small batch customization or large-scale manufacturing, this mold adapts efficiently to a wide range of production volumes.
