The plate is characterized in that a layer of aluminum wire felt and a layer of aluminum foil in the middle of the upper and lower layer net plates is added to the upper and lower layers of the aluminum mesh plate with different size of the rhombus mesh.
Its manufacturing processes are characterized by, including
Aluminum mesh processing: the top and bottom aluminum net plate moulds with different sizes of diamond mesh are installed in the die frame of punching machine to punch and make upper and lower aluminum panels.
Aluminum wire felt processing: the aluminum rod was processed by wire drawing machine to make aluminum wire about 1 microns in diameter. Then the aluminum silk felt was made by condensation and rolling, and the aluminum foil was flattened.
Rolling synthesis processing: four layers of aluminum material on the rolling press table are stacked in turn, and the aluminum fiber sound absorption plate is made by rolling molding.
Shearing process: shearing and trimming the sound absorbing plate of aluminum fiber;
Surface treatment: anodizing aluminum fiber sound-absorbing plate. The excellent sound absorption characteristics of the aluminum fiber sound absorption board can be widely used in the concert halls, theaters and buildings.
