Step 8
The figure is now ready for molding on the table in front of us. The plug connection to the arm has been completed, everything has been checked again for possible defects and found to be good. In order to be able to cast the figure, she now needs a so-called sprue. The material later flows into the mold through this.
Since resin is quite thin and the figure has very little volume, you only need small sprues. These consist of two 2mm thick round rods, which are glued under both shoes with a drop of superglue. This has the advantage that the material can flow into the mold on one side, while the air escapes from the mold on the other side. This prevents the formation of air bubbles and the resulting misfires. The large sprue block serves as a material reserve through which further resin sags.
Now all we have left is to glue the two parts onto a plastic plate and place four walls around it that form the molding box. Liquid silicone is then filled into this under vacuum and pressure. After a few hours, the mold walls can be removed again and the figure can be removed from the silicone by careful cutting with a sharp scalpel. The mold is now ready for the actual casting and can be filled with resin. Depending on the setting time, the first copies of the original can be obtained in a relatively short time.
The last step would be to paint the figure, which I will not go into here due to the lack of skills.
Thank you for reading, and see you soon,
