how to make a silicone case:
silicone case of the production process
silicone case high-temperature sulfur rubber is the main raw material molding vulcanization molding process and production comes out of silicone rubber products.
silicone case
silicone case the following procedure is required to pass through:
1. The draft design
Plane design and discussed 3D draft output
2. Mold design and manufacturing
3D draft input-CNC programming output-mold manufacturing
3. Raw material makes up (also called tried to get the gum, etc) :
Including the raw rubber mixed refined, color match colors, raw material the weight computation, etc
4. Vulcanization molding (also called oil pressure molding) :
Using high-pressure curing equipment after high-temperature vulcanization, make the silicone case raw materials into solid forming
5. Burr (also called processing, to flash, etc) :
From the mold of the silicone case of products will be joint some useless flash, and hole crumbs, will need to be removed; At present, in the industry, completely by the process is done by hand, and some factories and useful punches are completed.
6. Silkscreen:
The process with only some in the surface of the silicone case has a pattern of the silicone case products, such as black phone silicone case, for the user to operate buttons, often need to be in the position of the corresponding with the corresponding cell phone screen printing keyboard characters.
7. Surface treatment:
Surface treatment including the use of air gun dust removal;
8. Injection:
silicone case products in the ordinary state are easy to absorb dust in the air and have certain viscosity. On the surface of the silicone case spray a thin layer of oil feel, which can not only prevent dirt and can cause the feeling to be guaranteed.
9. Other:
Other processes including business-to-silicone cases some of the additional functions, such as glue, radium carving, P + R synthesis, optimized packaging, and other materials and assembly, etc.
