| Silicone rubber keyboard is a high temperature vulcanized rubber as the main raw materials by compression molding process and the production of silicone rubber products. A finished product of the silicone keyboard to go through the following procedures: A, raw material preparation (also called compound preparation, etc.) including: mixing the raw materials, the color of the color, weight calculation etc. Two, curing molding (also known as hydraulic molding): the use of high pressure curing equipment after high temperature vulcanization, so that the silicon collagen material into a solid state , Phi peak (also known as processing, Burr): from the mold and silica gel products joint some useless edges, Chad, need to be removed. At present, in the industry, this process fully completed by hand, some factories also useful punch. Screen printing: this procedure only in some in with designs on the surface of the silicone keyboard, such as silicone keyboard English letters and Arabic numerals, for users convenient operation keys, often need to in the corresponding to the printing position and mobile phone keyboard corresponding to the character. Five, surface treatment: by air dust including surface treatment; Six, fuel injection: silicone keyboard in the ordinary state, it is easy to absorb dust in the air, and has a certain viscosity. A thin layer of hand oil is sprayed on the surface of the silica gel keyboard, which can not only prevent the dust from the touch, but also guarantee the handle. Seven and other processes including businesses of silicone keyboard give some additional features, such as epoxy, laser carving, P + R synthesis, optimization of packaging, and other materials and parts assembly. |
