Abstract
The invention discloses an etching production technology of a speaker mesh. A metal strip or a single piece of plank stuff after an oil-cleaning is coated with a light sensitive material and is nipped between glass palettes or film palettes for exposing. Figures which are drawn in advance at the glass palettes or the film palettes are replicated at the metal strip or the single piece of plank stuff coated with the light sensitive material; a part which is not exposed is cleaned by water; an exposed part is kept wholly to be eroded by a ferric trichloride solution subsequently; and finally the light sensitive material is peeled off by a sodium hydroxide solution. Eroded parts are meshes, and saved part is the entity part of a speaker mesh product. The etching production technology of the invention has the low manufacturing cost, does not require a design mould and just designs a film palette or reproduces the glass palette to produce according to the photography eroding theory, which can flexibly adapt to the continuous updates of the speaker mesh. The technology is suitable for a large color-pipe screen production line for a mass production and is also suitable for other etching production lines at the same time.
