 Why is the tear strength of the silicone mold weak?
In order to reduce the viscosity of silicone rubber and pursue a good quality, you may add a lot of silicone oil into the silicon rubber when making molds. In fact, it might have just the opposite effect. The tension and the tear strength will be reduced badly with the addition of silicon oil. And the silicon molds will be in a weak and flimsy manner.

Step Three: Brushing cast & Perfusion Molding operation

Without exception, this step takes less than 10 minutes. Otherwise, it will cause , and no more further steps will be available.

Step Two: vacuum pumping

Notes: Moulding silicon rubber is a kind of flowing liquid and it contains two parts. Part A is a kind of white flowing liquid and part B is the curing agent. Remember to mix part A and part B evenly, otherwise the silicon rubber will be partly solidified and this will give birth to difficulties in your final operation. Whats more, the finished moulds will meet a short life. All of these will cause a waste of silicon rubber.

Step One: Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.
