The Process
16th March 2018
Well the first set of models have been cast. So we thought we would show you how they are made:
1. Blocks of clay are formed into a rough shape and left to fully dry
2. These blocks of dried clay are then sanded down to form the ships shape and size and then spray painted black to stop moisture from entering during the casting process
3. The ships are then placed into containers and filled with liquid silicone. These take about 3-4 hours to fully set.
4. Once the silicone has set, the ship is taken out which then leaves a hollow piece of silicone.
5. Liquid resin is then poured into the silicone mould. This has to be a quick process as the resin starts to set in 3 1/2 minutes. The moulds are then tapped to release any air bubbles. After 45 minutes, the resin can be removed from the silicone mould. The mould can then be reused multiple times.
These will come unpainted for you to paint to your specifications. More on that in the next post.
