• Q What material is used for the mold cavity and core in this injection mold?
  Both the cavity and core are made of P20 steel, which is pre-hardened to 30–36 HRC. This allows for direct machining without additional heat treatment and provides excellent corrosion resistance, making it ideal for medium-to-high volume production runs.
• Q How does the hot runner system improve molding efficiency?
  The hot runner system maintains precise temperature control throughout the melt delivery process, significantly reducing melt shrinkage and deformation. When combined with the standard side gate, it enables uniform filling across multiple cavities simultaneously, improving cycle time and part consistency.
• Q What temperature control accuracy does the cooling system achieve?
  The water-cooling channel design achieves a temperature control accuracy of ±0.5℃. This precise thermal management prevents product warping and dimensional deviations, which is especially critical for precision structural parts and large-format components.
• Q What types of plastic materials are compatible with this mold?
  This mold is suitable for a wide range of engineering thermoplastics, including PP (polypropylene), ABS (acrylonitrile butadiene styrene), and PA (polyamide/nylon). It is designed for medium to high-volume production environments requiring consistent part quality.
• Q Can this mold handle both left-hand and right-hand threaded products?
  Yes. The dual-groove design features independently engineered right and left tooth profiles. This makes the mold fully compatible with bidirectional threaded products, significantly expanding its application range across automotive, industrial, and consumer product sectors.
• Q What ejection system is used and what structures does it support?
  The mold uses a combined ejection system consisting of a pin-type ejector and an ejector plate. Working together, these two mechanisms provide reliable and consistent demolding performance for complex part geometries, including undercuts and deep-draw structures.
