Abstract: A method for applying hot melt adhesive powder onto a non-metallic object surface comprises the steps of applying a cleaning agent, applying a conductive liquid, radiating, spraying hot melt adhesive powder; and heating. A system for applying hot melt adhesive powder onto a non-metallic object surface comprises a convey belt, a radiation chamber, a spraying chamber and a heating chamber. The convey belt is used to deliver a non-metallic object treated by a cleaning agent and a conductive liquid through the radiation chamber where the surface of the non-metallic objected is radiated by ultraviolet rays and ozone and then through the spraying chamber where the surface of the non-metallic object is sprayed with charged hot melt adhesive powder, and finally into the heating chamber where the hot melt adhesive powder attached onto the non-metallic object will be melted into a liquid adhesive film ready to be bonded.
