The present invention provides a method of producing a topping hanger comprising: (a) inspecting raw materials; (b) calculating a formula; (c) mixing uniformly; (d) dehumidifying the raw materials; (e) injection molding a colored mixed body: introducing the dehumidified raw materials into an injection molding machine at temperature 200-350° C., and the colored mixed body being produced by injecting molding after adjusting parameters of molds; (f) injection molding a transparent exterior body: a transparent PET and acrylics being formed of the transparent exterior body outside of the colored mixed body by injection molding at temperature 200-350° C.; and (g) packing the products. The transparent exterior body fully coats with the colored mixed body via injection molding, and this feature effectively enhances quality and visual effect, and chemical and color stability of the products, and reduces the cost. The present invention reduces damage during objects with colors contacting human.

A method of manufacturing a clothes hanger is disclosed. The method includes adding ingredients into an injection machine. The ingredients made up of a wheat Fiber, a polypropylene, a polyethylene wax and a Talc Powder. The method heats and mixes the ingredients to melt the ingredients forming a composite mixture. The composite material is extruded into a mold, forming the hanger base. The hanger base is extracted from the injection machine and a hanger hook is inserted into the hanger neck.

The present invention discloses a PET-coated wire for a hanger wherein the wire is coated with PET to form a PET coating having a thickness of 0.03 to 0.05 mm, and a hanger made of the wire. The PET coating apparatus for a wire used for a hanger of the present invention comprises a preheating device 20 for preheating the cleaned wire 10 to 220 to 250° C., an extruder 30 and a dice 40 for coating the preheated wire 10 with PET to form a PET coating having a thickness of 0.03 to 0.05 mm, a cooling bath 50 for cooling the PET-coated wire 100, and a winding device 60 for drawing out and winding the cooled wire. The cooling bath 50 of the present invention is designed such that the wire passes through the cooling bath 50 having a length of 5 m three times for sufficient cooling when the wire proceeds at a high speed of 220 to 300 m/min.
