  a.Make a square frame with four pieces of wooden boards or rubber plates, then place the product which is covered

  Step Four: Operations for the external mold

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

d. Cover a third coat.(Note: if you have high requirements for the tension and the tear strength for the mold,please repeat step c and step d.Hence, the finished silicone moulds will have a good quality and a longer life, which can help you save cost and increase production efficiency.)

c. Cover a glass cloth on it after another 30 minutes of a second cross linking reaction, and use a brush pen or a brush to avoid any interstices.

b. After the cross linking reaction ( about 30 minutes ),brush a second coat which can increase the tension and tear

  reaction, and no more further steps will be available.

  Without exception, this takes less than 10 minutes. Otherwise, it will cause cross linking

  Step Two: vacuum pumping

   Step One:Take 100g of part A and add 2g of part B and mix the silicon rubber and the curing  agent evenly.Note:Molding 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 andpart 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 materials.
