ABSTRACT:
A method for imprinting woodprints onto the blade of fan generally includes the steps of 1) molding the plastic blade; 2) coloring the blade with woodprints; and 3) deploying a protective coating thereof. Characterized in that when the plastic blade is molded by injected molding, the surface of the plastic blade is formed with a plurality of recesses that stimulate the annular rings. The plastic material can be dyed with white or other colors that stimulates the wood color. Then the surface of the plastic blade is printed with a first UV coating that is darker than the color of plastic blade. Afterward, the UV coating is then flattened by means of a rubber knife such that the UV coating is left only within the recesses on the surface of the plastic blade. Before the UV coating is cured and dried, a brush can be used to brush the UV coating longitudinally to generate a pattern of fibrils. Then the coating is undergone the UV light to cure and dry the UV coating. Afterward, a second UV coating is deployed onto the surface by means of brush. Finally, the second UV coating is cured and dried by means of UV light and an UV protective film is coated onto the UV coating and then dried. The plastic blade having genuine woodprints is attained.
