Silicone rubber sleeve is made of silicone rubber, which is made of silica gel as the main raw material.
What are the following procedures for ordinary silicone cases?
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 completed 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 the surface needs to increase the aesthetic impression of some beautiful patterns.
1. At present, the most surface treatment is the spray oil, which can be better handled by mobile phone covers.
This is the simplest surface treatment.
Silica gel products are easy to absorb dust in the air and have a certain viscosity.
Spray a thin layer of oil on the silicone sleeve surface to protect against dust and feel.
2. Spray oil and radium. After the silicone sleeve is finished, spray a layer of colored ink on the surface of the silicone sleeve and then spray the design on the laser, then spray another layer of oil on the surface.
This process is quite popular at present.
3. Drop glue on the silicone sleeve that has been repaired and put colored liquid glue into the pattern.
4. Color printing, printing any color pattern on the silicone sleeve that has been fixed. This process can be a silicone sleeve that is not only beautiful but also three-dimensional.
It can print every surface of the silicone sleeve, and the pattern is very smooth and natural.
