Some Mold Making

Well, guess I won't be getting a new desktop for awhile...

Since I have a huuuuugeee break between my next exam, decided to make a two piece mold.
After some research, I found that two piece mold works out alot better than one whole mold in terms of pushing out air bubbles. If you don't have a vacum machine to suck out the air while casting, is better to make two piece mold than one whole mold.

Alright, so here are the pictures:

First, use super sculpey clay to make the base, so I can place on the parts. Since it won't stick on to silicon, once the top part is done, I can just pull it off and recycle it for next time.



And here is the mold:


However, the cast did not turn out good:


Mainly because of the path opening for me to pour in is too small, and the air is having a hard time escaping from the mold. So went back and fixed the mold by making a new pouring path for it.



In the picture, you can see that a new path added on the middle part, which starts from the side. This way, while pouring in the resin, the air will be pushed upward more easily and smoothly unlike the previous one, due to the fact that the path were too small for it.

And yes, the result of two seperate mold is definitely better than making one whole mold. Although it is slightly complicated, but is great way for casting if you don't own a vacum machine.
