Silicone products are based on silicone as the main raw material molded by the molding process and the production of silicone rubber products.
Ordinary silicone products need to go through the following processes
First, the preparation of raw materials
Including raw rubber mixing, color matching, raw material weight calculation, etc.
Second, curing molding
High-pressure vulcanization equipment adopts high-temperature vulcanization to form the solid raw material of silica gel
Silicone sleeves that come out of the mold will have some unwanted edges that need to be removed. Currently, this procedure is done entirely by hand in the industry.
Fourth, silk screen
This procedure is only used in some products on the surface of the silica gel silicone products, black mobile phone silicone sleeve, in order to facilitate the user to operate the keys, often need to screen the corresponding position in the corresponding phone keypad characters. Or the surface needs to increase the beautiful printed some beautiful patterns.
Fifth, the surface treatment
1. At present, the surface is the most spray handle sense of oil, this can be a touch of mobile phone sets feel better. This is the simplest surface finish. Silicone products in the general state is easy to adsorb the dust in the air, and has a certain viscosity. Silicone sleeve sprayed with a thin layer of surface feel oil, both anti-dust and feel can be guaranteed.
2. Injection plus laser engraving, silicone sleeve repair the edge of the silicone sleeve after spraying a layer of colored ink laser in the pattern, and then spray a layer of surface feel oil. This craft is more popular at present.
3. Dijiao, in the edge of the silicone casing has been repaired dripping colored liquid glue pattern.
4. Color printing, in the already repaired edge of the silicone sleeve printed on any color pattern, the process can be silicone sleeve is not only beautiful and three-dimensional sense of strong. Feel good. It can print patterns on each side of the silicone sleeve, and the pattern is very smooth and natural.
