Silicone mold vacuum casting is a widely used manufacturing way for prototype making,especially for low volume production.I would like to introduce some knowledges on silicone mold making process with you here.

Silicone mold Material
Silicone is a kind of soft material which EbyTon use for silicone mold making. It is liquid in normal status, and the color flexible; when using it, you can add hardener in proportion into the silicone to solidify the silicone material within several hours
.

Silicone mold making process
Silicone,as one kind of flowing liquid,whatever the color it is , the quality keeps the same. Part A is the flowing silicone liquid, Part B is the hardener.The silicone mold making process starts as this:
1.handle the prototype or sample well first;
2.take out a certain amount of silicone,add 2-3% hardener,then stir it;
3.After stiring ,to defoam;
4.Pour it into the boxed which prepared before in vacuum casting machine;
5.Wait for 2-3 hours ,it will solify;
6.Take out the solified mold,seperate up and down half of the mold ,take out the prototype inside;
7.Put the silicone mold into oven to bake for 4 hours to make it steady;
8.Take out mold from the oven.

After the above steps,the silicone mold making finished ,it has the advantage of no deformation, no shrink, heat-resistant, and can be used repeatedly.And silicone mold provides the fast duplicate for product, meets up with your expectation of rapidly making prototypes for projects in tight schedule.
