Injection Molding Screw Tip

Nanhaiya Injection Molding Screw Tip is the critical interface between the screw and the nozzle, designed to optimize material melting, minimize shear degradation, and prevent backflow. Made from premium alloy steel with surface-hardened treatment, the assembly guarantees dimensional accuracy and robust durability. It is compatible with different screw diameters and injection machine brands, providing consistent shot weight and smooth operation.

Technical Parameters

Features and Applications

The screw tip ensures uniform plasticizing, stable melt pressure, and reduced material degradation. Widely applied in thermoplastics molding including PE, PP, ABS, and PVC, especially for high-precision components such as automotive parts, household appliances, and packaging products.

Product Details

Each screw tip undergoes CNC machining, heat treatment, and precision polishing. Optional designs include reverse-flow tips for special polymers and customized thread patterns to optimize melt flow. Nanhaiya offers technical guidance for installation, adjustment, and maintenance, ensuring long-term stable performance.
