Material Preparation: Accurately weigh an appropriate amount of low-hardness liquid silicone rubber components A and B according to the product instructions, ensuring a 1:1 ratio. For example, if a skin model of a certain size is to be made, calculate the required mass of components A and B based on the density of the silicone rubber and the volume of the model, using a high-precision electronic balance for weighing.

Mixing and Stirring: Pour the weighed components A and B into a clean container and mix thoroughly using mechanical or manual stirring. For mechanical stirring, a low-speed mixer can be used, set to an appropriate stirring speed, such as 200 - 300 RPM, with a stirring time of 3 - 5 minutes to ensure uniform mixing of the two components. For manual stirring, use a stirring rod to stir slowly in the same direction, extending the stirring time to 5 - 8 minutes, while taking care to avoid generating excessive bubbles.

Vacuum Defoaming: The mixed silicone rubber will contain a certain amount of bubbles, which, if not removed, will affect the quality of the model. Pour the mixed silicone rubber into a vacuum defoaming machine and apply a vacuum at -0.08 MPa for 3 - 5 minutes. During this process, the bubbles in the silicone rubber will gradually expand and escape. When no obvious bubbles are observed on the surface of the silicone rubber, the defoaming operation is complete. Note that during the vacuum process, the silicone rubber will expand in volume due to bubble expansion, so the container should not be filled too full to prevent overflow.
