High-Precision Plastic Centrifugal Fan Impeller | Custom Injection Molded Blower Wheel for Automotive HVAC & Air Purifiers


Product Overview

This is a high-performance centrifugal fan impeller (squirrel-cage blower wheel), custom-manufactured using advanced precision injection molding. It features a multi-blade design engineered for high-efficiency airflow, low noise levels, and stable operation in high-speed rotation environments.
At JST Mold, we specialize in producing complex rotating components. This impeller demonstrates our ability to mold dozens of thin, curved blades with perfect symmetry, ensuring excellent dynamic balance—a critical factor in preventing vibration and extending the motor life of automotive and household appliances.


Key Features

  • Optimal Aerodynamic Design:Features numerous precisely angled blades designed to maximize air pressure and volume while minimizing turbulence and acoustic noise.
  • Superior Dynamic Balance:Manufactured with extreme dimensional consistency to ensure the center of gravity is perfectly aligned, allowing for vibration-free operation at high RPMs.
  • Integrated Center Hub:Includes a reinforced center hub for secure mounting to motor shafts, designed to handle high torque and frequent start-stop cycles.
  • High-Durability Materials:Typically molded with engineering plastics such as PP, PA66 (Nylon), or ABS, offering excellent impact resistance, heat stability, and long-term structural integrity.
  • Precision Thin-Wall Molding:Demonstrates our expertise in filling complex, multi-fin molds without defects like short shots or air traps, ensuring every blade is uniform.
