Silica gel products factory production of silica gel set, he the production process of silica gel set based on silica gel as the main raw material by moulding vulcanization molding process and production of silicone rubber products. Ordinary silica gel sets required to pass through the following process? Raw material preparation including rubber mixing, color matching, calculate the weight of the raw materials, etc. , vulcanization molding by high temperature vulcanization using high pressure curing equipment, make the silicone raw materials into a solid forming, trimming off out of the mould of the silicone set of products will be jointly and severally useless burrs, will need to be removed; At present, in the industry, this process is completely done by hand. Screen printing the process only used in some in silicon surface patterned silicone product package, black phone silicone sets, buttons for convenience operation, often need to screen printing in the corresponding position with mobile phone keyboard corresponding characters. Or on the surface of some beautiful pattern on the need to increase the beautiful printing. 1. Surface treatment at present most is spray hot oil, this can be a mobile phone sets of touch up and feel better. This is the most simple surface treatment. Silicone products in normal condition easy adsorption of dust in the air, and has a certain viscosity. On the silica surface of spray a thin layer of hot oil, both can prevent dust and can make the feel is guaranteed. 2. Injection and radium vulture, silica gel sets after repairing the edge in the surface of the silica gel set after spraying a layer of color ink in a laser injection pattern, and then the surface spray a layer of hot oil. This process at present more popular. 3. Glue, silica gel on the edge of has been repaired on colored liquid glue to make pattern on the drops. 4. In has been repaired color printing, printed on the silicone set near the arbitrary color pattern, this process can be silica gel set not only beautiful and stereo sense is strong. Feels nice. It can silicone sets are printed on each face design, and design is very smooth and natural.
