Abstract

See full text

A manufacturing method of an axial air moving device. A model of the axial air moving device includes a hub and blades. The axial projection of blades is partially overlapped in the axial direction of the hub. The model of the axial air moving device is parted in the axis direction of the hub. The blades are divided into multiple parting models non-overlapped in the axial projection. A mold manufacture using axial demolding and an injection molding are performed and the parting models are connected. Therefore, the axial air moving device with overlapped blades and better fluid performance is achieved through the axial demolding method.
