Disclosed is a method for manufacturing a soundproofing board part having improved sound absorption performance. The soundproofing board part is manufactured by using, as a material, a recycled soundproofing material which contains a polyurethane foam having excellent sound absorption performance and impact resilience during the press molding; and by producing a sound absorption part on the back surface of the soundproofing board part through a remolding processing method. Also disclosed is a soundproofing board part manufactured by the method. Accordingly, sound absorption performance of the soundproofing board part is improved by about 20% or greater, manufacturing cost thereof may be reduced by recycled resources utilizing waste sheets, and manufacturing process may be simplified compared the related art.

A vehicle sandwich structure composed of a foamed resin article in sheet form forming the core, a fiber-reinforced composite layer forming a surface material that is located on one or both sides of the foamed resin article in thickness direction; forming a binding layer of core and surface materials between the foamed resin article and the fiber-reinforced composite layer; a large number of glass fibers being inserted within said foamed resin article; more than 70% of total glass fibers being the glass fibers which form an angle between the longitudinal direction of each glass fiber and said foamed resin article, the angle of which satisfying a range from 45° to 90°.

A sonic label welding device for welding multiple labels together using ultrasonic welding is disclosed. The sonic label welding device comprises a digital controls main menu screen which includes touch screen buttons that are utilized to go to specific screens to program the device to perform in a certain manner. For example, a user can press the cut to length button if wanting to cut a label to a specific length, or the label weld count button to specify the number of labels being sonically welded. Further, the sonic label welding device comprises a head for allowing multiple labels to be assembled under pressure and an anvil for directing the high frequency vibrations. A method of manufacturing a multi-layer care label is also disclosed.

An inductor includes a support having first and second coils formed on first and second surfaces thereof, respectively; a body embedding the support therein so that end portions of the first and second coils are exposed through first and second surfaces of the body opposing each other, and including a first magnetic part disposed in cores of the first and second coils and on upper and lower surfaces of the first and second coils, respectively, and second magnetic parts disposed on upper and lower surfaces of the first magnetic part, respectively; and first and second external electrodes formed on outer surfaces of the body to be electrically connected to the end portions of the first and second coils, respectively. The second magnetic part has a content of a hardening accelerator greater than that of the first magnetic part.

A fibrous component for a vehicle exterior includes a skin layer having a multilayer structure comprising a laminated web including a reinforcing fiber and a binder fiber, the skin layer including pores that absorb sound; a sound absorbing pad layer disposed on an inner side of the skin layer and absorbing sound; and an adhesive layer disposed between the skin layer and the sound absorbing pad layer. The adhesive layer adheres the skin layer and the sound absorbing layer to each other.

A method for thermoforming an article includes extruding a sheet of material, conditioning the sheet with a roller, thermoforming the sheet to provide a web, and cutting the web to provide the article.

A Corrosion Inhibiting Sprayable Thermoplastic (“CIST”) cover is formed by spraying melted CIST onto a mold, allowing the CIST to cure, removing the cured cover from the mold using a series of cuts if necessary, positioning the cover on a mechanical assembly whose shape is significantly identical to the mold, and fusing the cuts on the cover using heat to reform the cover on the mechanical assembly.

A method for manufacturing a composite part with continuous fiber reinforcement and a polymer matrix from a composite preform. On one of the faces of the composite preform, a demarcated layer of thermoplastic polymer is deposited using an additive manufacturing method.
