China Injection Mould for Rear Retaining Plate - Quality Suppliers and Factory Solutions
-
1. Material Advantages
◎ The P20 steel cavity is pre-hardened to a hardness of 30–36HRC, allowing for direct machining and corrosion resistance; the 45# steel mold base is heat-treated to achieve a tensile strength exceeding 600MPa.
-
2. High-Efficiency Molding
◎ The hot runner system is temperature controlled to reduce melt shrinkage and deformation, and combined with the side gate, it achieves uniform filling of multiple cavities.
-
3. Precise Cooling
◎ The water-cooling channel design ensures temperature control accuracy of ±0.5℃, preventing product warping.
-
4. Reliable Demolding
◎ The pin-type ejector and ejector plate work together to meet the demolding needs of complex structures.
-
5. Dual-Groove Adaptation
◎ The right and left teeth are designed independently, compatible with bidirectional threaded products, expanding application scenarios.

What material is used for the mold cavity, and what are its advantages?
The mold cavity is made from P20 steel, which is pre-hardened to 30–36HRC. This allows for direct machining without additional heat treatment, provides excellent corrosion resistance, and ensures long service life for medium to high-volume production.
-
How does the hot runner system improve molding efficiency?
The hot runner system maintains precise temperature control to reduce melt shrinkage and deformation. Combined with a side gate design, it ensures uniform filling across multiple cavities, resulting in consistent part quality and faster cycle times.
-
What is the temperature control accuracy of the cooling system?
The water-cooling channel design achieves a temperature control accuracy of ±0.5℃. This level of precision effectively prevents product warping and ensures dimensional stability of molded parts.
-
What types of products is this mold suitable for?
This mold is suitable for a wide range of applications including automotive parts (tailgates, interior trim), industrial fasteners and connectors, daily-use containers, electronic structural components, and general injection-molded parts using engineering plastics such as PP, ABS, and PA.
-
Can this mold handle bidirectional threaded products?
Yes. The dual-groove design features independently designed right and left teeth, making it fully compatible with bidirectional threaded products. This expands the range of applicable scenarios and reduces the need for separate molds.
-
How does the ejection system work for complex structures?
The mold uses a combination of a pin-type ejector and an ejector plate working in conjunction. This dual-mechanism approach reliably handles the demolding requirements of complex part geometries, minimizing the risk of part damage during ejection.
