Abstract
A centrifugal fan impeller structure includes a hub and multiple blades extending from an outer circumference of the hub. Each blade has a fixed end, a free end, an upper end face, a lower end face, a front end face and a rear end face. The front and rear end faces define therebetween a thickness. The thickness ranges from 0.05 mm to 0.15 mm. The are two inclinations between the upper and lower end faces of the blade, whereby the thickness of the blade is minified to increase the number of the blades. By means of the inclinations, the blades are not subject to breakage in the demolding process.
