[0002] Speaker mesh, often referred to as a speaker grille or protective mesh, is a material used to protect speaker speakers and internal components. It not only protects against dust, dirt, and physical damage, but can also affect sound quality to a certain extent. Due to its grille-like shape, speaker mesh requires hot pressing equipment during production, which can then be installed later when the mesh is commissioned. Existing speaker mesh hot pressing equipment utilizes specialized molds to heat-press the cut mesh material, achieving an efficient and precise molding process.

[0003] However, in the hot pressing process of common speaker mesh hot pressing equipment, mesh debris after punching is easily retained in the mold cavity, affecting the next hot pressing of the mesh, and even causing damage or deformation of the speaker mesh. In view of this, we propose a hot pressing equipment for speaker mesh. Utility Model Content
