Electric Fan Molds

The key point of fan mould is the choice of gates at the turning point. It must be selected to ensure same plastic filling pressure in the cavity and same pouring distance. At the same time, we must know that different temperature between different parts of the mold will affect the plastic melts unevenly, the gravity of the blades will be different. There are ugly noise when rotating. Hafo mould can enable the same average injection and cooling effect for all parts of the HIPS blade mold and the AC wheel fan mold.
