2. Take 100g of part A and add 2g-4g of part B and mix the silicone rubber and curing agent evenly.
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. What’s more, the finished moulds will meet a short life. All of these will cause a waste of silicon rubber
3. Vacuum pumping
Without exception, this step takes less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available.
4. Pouring molding
It is suitable for simple products with the smooth surface. Without any mold lines, which helps you save time and is easy for operation. Evenly and slowly perfuse the mixed silicone rubber into the square frame. After the cross linking reaction and the silicone rubber turns dry, you can take the products out. Thus, the mold has been done.
