The production process of silica gel keys generally has the following processes:
A, rubber preparation: including raw rubber mixing, color matching, weight calculation of raw materials, etc.
Two, molding processing: the use of high pressure curing equipment after high temperature curing, so that the silicone raw materials into solid forming.
Three, edge removal: the silicone product taken out of the mold will be associated with some useless burrs and hole chips, which need to be removed; At present, in the industry, this working procedure is completed completely by hand, some factories also useful punch is completed.
Four, screen printing: this process is only used in some of the silicone keyboard with patterns on the surface, such as the English letters and Arabic numbers on the silicone keyboard, in order to facilitate the user to operate the keys, often need to screen the corresponding characters in the corresponding position of the mobile phone keyboard.
Five, surface treatment: surface treatment includes dust removal with an air gun.
Six, oil injection: silicone keyboard in the ordinary state is easy to absorb dust in the air, and has a certain viscosity. Spray a thin layer of feel oil on the surface of the silicone button, which can prevent dust and ensure the feel.
Seven, according to the requirements required: glue, radium carving, optimization of packaging, etc.
