PURPOSE: An environment-friendly buoy manufacturing method is provided to reduce the corrosion of the buoy caused by sea wave, salt water, and sun light. CONSTITUTION: An environment-friendly buoy manufacturing method is formed by a two forming films(1-1) and a vacuum pipe. The forming films vacuum-molded in order to prevent the generation of bubbles on the buoy are located in a projection-formed lower mold(65). Minute holes are formed on the forming films by a projection-formed upper mold(55). The edges of the forming film comprising minute holes are arranged to be faced with each other and input to a forming frame. The forming frame is heated in 100 to 200°C and shrunken on and thermally fused on the buoy.

Abstract:
PURPOSE: A film for protecting surface of bath and method and apparatus for making the same are provided, wherein the film functions to relieve impact by allowing a space to be formed between stacked upper and lower baths and also to prevent the surface of the bath from being scratched. CONSTITUTION: In a film for protecting surface of bath and method and apparatus for making the same, the film comprises foamed portions(22) formed on the surface thereof and cutting lines formed on the opposite edges. The method comprises a step for heating a thermoplastic film(30), a step for detecting the deflection of a heated portion(32), a carrying step for carrying the film(30) and simultaneously forming cutting lines on the opposite edges, a forming step for combining an upper and lower molds(40, 50) and forming, a vacuum suction step for forming foamed portions(22) on the thermoplastic film(30) by vacuum suction force, a step for cooling a formed portion(35), and a cutting step for cutting the formed portion(35) and separating it from the thermoplastic film(30). The apparatus comprises heaters(H1, H2), a device for detecting the deflection of a heated portion(32), carrying chains(70) for forming the cutting lines on the opposite edges of the thermoplastic film(30), a lower mold(50) having suction holes(54) formed between forming protrusions(54) and an antiskid sheet(56), an upper mold(40) of which press surface is covered with a heat insulation sheet(46), a device(80) for cooling the formed portion(35), and a cutter(90) for cutting the thermoplastic film(30).
Abstract:
PURPOSE: A vacuum mold having three dimensional design patterns of a reverse direction and a vacuum forming method using the same are provided to simplify a process because a process decaling 3D patterns on an insert sheet while forming vacuum of the insert sheet. CONSTITUTION: A vacuum mold having three dimensional design patterns of a reverse direction comprises a lower mold(140) and 3D patterns(160). The 3D patterns are formed in a surface of the lower mold. An insert sheet arranged in the upper part of the lower mold is absorbed in the surface of the lower mold by vacuum pressure. The 3D patterns are projected on the insert sheet. A vacuum mold(100) comprises a vacuum hole(144) and a vacuum pump(150). The vacuum hole penetrates the inside of the lower mold. The vacuum pump supplies the vacuum pressure to the vacuum hole through a vacuum supply pipe. The vacuum supply pipe is connected to the vacuum hole.

Abstract:
A method of forming a composite door is disclosed. The method comprises: mixing together a thermoplastic polymer with an organic fibrous material in a ratio such that the organic fibrous material constitutes 40 to 60 percent by weight of the mixture; extruding the mixture under heat and pressure to create a thin sheet form; cutting the sheet to a predetermined size; removing material from at least one surface of the sheet to create a uniform surface of exposed fibrous particles that has a homogenous appearance devoid of obvious fibrous particles; thermoforming the sheet to impart to the at least one surface an exterior three dimensional door surface to create a thin door facing; and assembling two of the termoformed thin door facings, a peripheral frame and a core material into a door.
