Initially, Elastosil A and B in 9:1 ratio. 90g from part A (white) and 10g from part B (Red) were measured and poured into the mixing cup.
Then the mixing cup was put into the centrifugal mixer and the mixing process was run until both materials mixed uniformly.
The 2 parts of main mold were hot glued and the mixture was poured into the main mold.
Then the mixture was poured into the base mold until half of its depth got filled with the mixture.
After that the molds were placed in a vacuum chamber and the valve was slowly turned on.
After the popping up of bubbles, the valve was slowly released and air was let back to the chamber.
The bubbles were popped, using a barbecue stick that had not been drawn into the surface.
Before putting the mold into the oven excess Elastosil was wiped off from the main mold and piece of paper was added on top of the Elastosil of the base mold.
Later the both molds were placed in the pre-heated oven at 65°C for 15 minutes.
While this procedure was repeated, the level of Elastosil in the chamber mold dropped at certain intervals. When this happened, extra Elastosil was poured and it was returned to the oven for another 15min for cure.
Then both molds were removed from the oven and the top part of the actuator was removed from the mold. Then a fresh mixture of Elastosil was made, of 10g (9g of part A + 1g of part B) and a small amount of mixture was poured into the edge of the base mold. Then the top part of the actuator was placed on the base mold and edges were sealed using the extra Elastosil mixture. After that, the joint part was placed in the oven again for 15 minutes.
Finally, the cured actuator was removed from the oven and the actuator was removed from the base molds.
