 No deformation

Favorable hardness

High temperature resistance, acid and alkali-resistance and ageing resistance

Operations of silicone rubber mold making

Step One: Take 100g of part A and add 2g 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 is more, the finished moulds will meet a short life. All of these will cause a waste of silicon rubber.

Step Two: vacuum pumping

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

Step Three: Perfusion Molding

The perfusion molding is an easy way to make molds, it is  Slowly and evenly perfuse the mixed silicon rubber into the square frame. After the cross linking reaction.
