Why Do Fan Blade Molds Require High-Precision Mold Bases?

• Precision Molding Requirements: Fan blades feature complex curved surfaces and demand extremely high dimensional accuracy (typically with tolerances within ±0.1mm, and up to ±0.01mm for critical areas) and surface smoothness to ensure aerodynamic efficiency and low-noise operation.

• High Load and Long-Term Production: Fan blade molds must operate continuously under high temperature and pressure. The mold base must exhibit excellent strength and thermal stability to avoid deformation or fatigue during prolonged injection molding, ensuring mold longevity and production stability.

• Standardization and High-Volume Production: Similar to toy car parts, fan blades also need to meet the requirements of "standardization + high output." A high-quality mold base enables molds to achieve efficient and stable production of thousands of parts per hour.
