Evilgenius Batarang Mold - Instructions & Diagrams


Hey everyone,
Been away for a few days and finally got things together to continue the progress on the batarang for Evilgenius.
The master was finally cleaned up and ready to be commited to an open back silicone mold.
The following is a brief how to on the process of making this very simple mold.
In the first picture we see that the original master has been adhered to a cardboard backing with CA/super glue.

Once the piece is firmly adhered to the backing I use a clay referred to as "Clean Clay" available
from Silpak inc. This clay will not react with the silicone that the mold will be made from, as most
oil based clays have a tendency to produce a noxious chemical reaction to silicone and can also
ruin the mold.I use this to make sure that there are no areas of the master which will
allow silcone to seep underneath. This can also be used to fill any small imperfections in the master.

The next step is to put up the mold retainer walls. Many materials can be used to make your
mold walls, the best ive found is foam core board, but for the purposes of this quick and cheap
mold I am just usiing cardboard. Hot glue is used to glue the mold walls to the backing board.
I like to make my mold walls at least 1/2 inch from the master so as to prevent warpage
from the weight of the resin that will be cast into the piece. You can make thinner closer
molds to save materials but over years I have learned that the slightly thicker mold wall allows
for better strength of the mold shape and also gives some material for the heat from the curing
resin someplace to go and will make your mold actually last longer.

Once I am satisfied that there is enough hot glue around the mold walls base so as to insure
that nothing will leak out, I mix and pour the silicone. Make sure to use gloves and be familiar
with your materials safety data sheet when working with this and any other potentially
hazardous material. Silicone can quite easily absorb into your skin and in some cases cause
massive allergic reactions.I make sure to pour enough silicone to completely cover the top
of the master about 1/4 inch thicker than the actual piece. Again this is for support and to make
a strong durable mold that will last.

Once the mold is cured I remove the outer retainer walls.

The silicone mold can now be seperated from the master. Spray release is used on the inside
of the mold and the resin can now be mixed and poured into the mold! This mold should yield
many copies and last for several months under fairly regular careful use.

Thats all for now, next up will be painting!

No mother mold is necessary for an open backed mold. Yes I did make sure that my table was perfectly level.
