Operations for RTV 2 silicone moulding rubber HY630:

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

  Step Two: vacuum pumping

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

  reaction, and no more further steps will be available.


  Step Three: Brushing cast & Perfusion Molding operation

Brushing cast:

a. Evenly brush the mixed silicon rubber on the product which is covered with mold spray with a brush or a brush pen.

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

strength of the mold.

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.

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.)


  Perfusion Molding

  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.


  Step Four: Operations for the external mold

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

 with the finished silicon rubber mould in the middle.

  b.Slowly and evenly perfuse the gypsum to the square frame. Also you can brush the resin on the product which is covered with the finished silicon rubber mould with a brush or a brush pen. Repeat this process two or three time after the cross link reaction.
