 Operate Instruction:


Step 1 prepare the original molds

Make sure your original molds perfect. fix it on a board. And fix the original mold on a 

board, then used four piece of board to enclose the original molds .


Step 2 Weight part A & part B according to the mix ratio recommended

Weighting two parts in Electronic scale with mix ratio 100:2 or 100:5. 

Eg: Take 100g part A and 2g part B


Step 3 Stirring evenly

Remember to mix part A and part B evenly, otherwise the silicon rubber 

will be partly solidified and bring  problems in your final operation. What’s more, the finished 

molds will meet a short life.All of these will cause a waste of silicon rubber.


Step 4 Vacuum pumping

For releasing the air bubbles, after mixing evenly, put the mixture in to 

vacuum pumping for 3-5 minutes, without exception, this step takes less 

than 10 minutes. Otherwise, it will cause cross linking reaction, and no 

more further steps will be available. 


Step 5 Pouring or Brushing

Pouring:Pouring the silicone rubber to the frame from a corner, make the silicone rubber 

flow to the frame smooth.After 3-5 hours later, can demould the silicone mold, 

Its will be better for mold to demould after 24 hours
