5. Calendering
Silicone rubber is kneaded and mixed with carbon black, silicone oil, etc. to form a kneaded rubber, and then rolled out to form a sheet.
The film produced by calendering has obvious differences in the physical and mechanical properties in the longitudinal and transverse directions. This phenomenon is the calendering effect. Specifically, the longitudinal tensile strength of the film is greater than the horizontal direction, the elongation at break of the film is greater than the longitudinal direction, and the longitudinal shrinkage of the film is greater than the transverse direction.
The calendering effect is the result of the orientation of macromolecules and needle-like, sheet-like complexing agents in the rubber compound along the rolling direction during the rolling process. The size of the rolling effect is related to the composition of the rubber, the rolling temperature, the speed, and the speed ratio.
For larger products, such as silicone tablets, silicone plates.

6. perfusion
The operation method of the filling mold or the filling mold: The filling mold or the filling mold is used for relatively smooth or simple products. There is no mold line to save labor and time, which is to surround the product or model you want to copy with a plastic or glass plate. Then, pour the vacuumed silicone directly onto the product. After the silicone is dried and formed, take out the product and the mold is formed. (Note: The injection mold is generally made of relatively soft silicone. This makes it easier to remove the mold. Will damage the product in the silicone mold). It is a combination of solid and liquid, using products such as mobile phone cases, sex toys, etc.
