| 摘要 |
The present invention relates to a method to manufacture a sound-absorbing panel and, more specifically, to a method to manufacture a sound-absorbing panel capable of maximizing the absorption of sound and sound waves by integrating a foam having sound-absorbing holes, a protrusion part arranged in a coupling part, and reinforcement protrusions with a V-shaped cross section and reducing manufacturing hours and costs as the foam is formed on a frame right after the extrusion molding of the frame for a manufacturing process to be continuously performed. The method to manufacture a sound-absorbing panel comprises the following steps of: discharging a plate-shaped frame formed in an extruder; transferring the frame discharged from the extruder using a transfer roller and forming a foam by spraying a foaming solution to one surface of the frame using a spraying nozzle arranged in one side of the transfer roller; and forming multiple sound-absorbing holes on the foam. |
