China Injection Mould Supplier for Rear Retaining Plate - High-Quality Factory Manufacturing 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.

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 without additional heat treatment and provides excellent corrosion resistance for long-term production use.
-
Q How does the hot runner system improve molding efficiency?
The hot runner system maintains precise temperature control throughout the melt delivery process, reducing shrinkage and deformation. Combined with a side gate design, it ensures uniform filling across multiple cavities, resulting in consistent part quality and reduced cycle times.
-
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 thermal management effectively prevents product warping and dimensional deviation, ensuring consistent dimensional stability across all produced parts.
-
Q What types of plastics are compatible with this injection mold?
This mold is suitable for medium to high-volume production using a wide range of engineering plastics, including PP (polypropylene), ABS (acrylonitrile butadiene styrene), and PA (polyamide/nylon). Its robust construction and precise cooling system support consistent results across these materials.
-
Q How does the dual-groove design benefit production flexibility?
The independently designed right and left teeth cavities allow the mold to produce bidirectional threaded products within a single tool. This expands application scenarios significantly, making it suitable for a wide range of fasteners, connectors, and consumer products without requiring separate tooling.
-
Q What industries can benefit from this mold design?
This mold is designed for multiple industries, including automotive parts (such as tailgates and interior trim), industrial parts (flanges and brackets), daily necessities (large containers and shells), electronic components (precision structural parts), and general injection molding applications requiring consistent quality and high-volume output.
