Silicon Mold – 2nd attempt

A second attempt was made to pour a silicon mold around the shaped resin form.

The pour was not the best, and the liquid resin did not flow correctly. An ugly bumpy lump of silicon can be seen in one corner. Normally the silicon would flow and form a very flat level on each half of the mold.


The first attempt failed when attempting to degas the liquid silicon. In the first attempt the liquid silicon immediately cast inside the vacuum chamber into a spongy foam. The silicon resin was 12 months old, and has a recommended shelf life of 6 months.

It remains to see if this 2 part mold will be able to retain the resin without leaking!
