I’ve been experiencing problems with trapped air in the mold during
wax injection. I’m using silicone to make my molds. I’ve tried to
cut some vents and applied talcum in them to allow air to escape,
but it is not working. Even doing that I’ve still got some regions
not filled thoroughly in the model. Maybe I have cut vents in a
wrong way. How is the correct way to cut or form mold vents? Is it
possible to send me some mold pictures showing some examples of mold
I would really appreciate that.
