High-Quality Injection Mould for Rear Retaining Plate - China Suppliers & Factory
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.
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.
Precise Cooling
◎ The water-cooling channel design ensures temperature control accuracy of ±0.5℃, preventing product warping.
Reliable Demolding
◎ The pin-type ejector and ejector plate work together to meet the demolding needs of complex structures.
Dual-Groove Adaptation
◎ The right and left teeth are designed independently, compatible with bidirectional threaded products, expanding application scenarios.
Automotive Parts
Plastic parts that require high surface finish and dimensional stability, such as tailgates and interior trim.
Industrial Parts
Fasteners and connectors with symmetrical threads, such as flanges and brackets.
Daily Necessities
Large containers, shells, and other mass-produced products that require rapid cooling and molding.
Electronic Components
Precision structural parts, using a water-cooling system to ensure low thermal deformation.
General Injection Molding
Suitable for medium to high-volume production of engineering plastics such as PP, ABS, and PA.
