High-Quality Injection Mould for Rear Retaining Plate - Leading China Suppliers & Factory Solutions
Product Features
-
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.

Frequently Asked Questions
-
Q What material is used for the mold cavity and core?
Both the cavity and core are made from P20 steel, which is pre-hardened to 30-36HRC. This allows for direct machining and provides excellent corrosion resistance, ensuring long-term durability and stable performance.
-
Q How does the hot runner system improve molding efficiency?
The hot runner system uses precise temperature control to minimize melt shrinkage and deformation. Combined with a normal side gate design, it ensures uniform filling across multiple cavities, reducing cycle times and material waste.
-
Q What is the temperature control accuracy of the cooling system?
The water-cooling channel design achieves a temperature control accuracy of ±0.5℃. This precise cooling effectively prevents product warping and dimensional deviations, ensuring consistent part quality throughout high-volume production.
-
Q What types of plastics are compatible with this mold?
This mold is suitable for medium to high-volume production using common engineering plastics such as PP (polypropylene), ABS, and PA (nylon). Its robust construction supports a wide range of thermoplastic materials for diverse industrial applications.
-
Q What industries can this injection mold be applied to?
This mold is widely applicable across multiple industries, including automotive (tailgates, interior trim), industrial manufacturing (flanges, brackets, fasteners), consumer goods (large containers, shells), and electronics (precision structural components).
-
Q How does the dual-groove design expand product applications?
The dual-groove adaptation features independently designed right and left teeth cavities (2 cavities: right + left), making the mold compatible with bidirectional threaded products. This versatility significantly broadens the range of application scenarios and reduces the need for separate tooling.
