High-Quality Injection Mould for Rear Retaining Plate - China Suppliers & Factory Solutions
◎ 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.
◎ 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.
◎ The water-cooling channel design ensures temperature control accuracy of ±0.5℃, preventing product warping.
◎ The pin-type ejector and ejector plate work together to meet the demolding needs of complex structures.
◎ 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 and provides excellent corrosion resistance, ensuring long-lasting mold performance.
-
Q What type of gate system does this mold use?
This mold uses a combination of a hot runner system and a normal side gate. The hot runner system provides precise temperature control to minimize melt shrinkage, while the side gate ensures uniform filling across multiple cavities.
-
Q How accurate is the cooling system temperature control?
The water-cooling channel design maintains temperature control accuracy of ±0.5℃. This precision effectively prevents product warping and ensures consistent part quality throughout production runs.
-
Q What engineering plastics is this mold compatible with?
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).
-
Q Can this mold handle bidirectional threaded products?
Yes. The mold features independently designed right and left teeth (dual-groove adaptation), making it fully compatible with bidirectional threaded products. This design significantly expands the range of applicable production scenarios.
-
Q What ejection system does this mold use for complex structures?
The mold employs a combined ejection system consisting of both a pin-type ejector and an ejector plate. Working together, these two mechanisms reliably meet the demolding requirements of complex and intricate part structures.
