Abstract
A fan impeller has a fan hub, an outer circular frame surrounding the fan hub, and metallic blades independent from one another. Two ends of each of the metallic blades are a root and a distal end respectively, at least a portion of the root is embedded in the fan hub, and at least a portion of the distal end is embedded in the outer circular frame. The metallic blades, the plastic fan hub and the plastic outer circular frame are connected by means of insert molding, so that the number of the blades can be increased to provide increased air output.
