1.Preparation

Prepare the necessary tools, such as rulers, knives, brushes, paper board, etc.

2.Fix the original mold and make a square frame

3.Spray or brush a layer of release agent

4.Weigh part A&part B according to the mixing ratio

5.Stirring evenly

Mix part A and part B evenly, otherwise the silicone rubber will be partly solidified and bring problems in final operation.

What’s more, the finished molds will meet a short life.

6.Vacumm pumping

For releasing the air bubbles, after mixing evenly, put the mixture into vacuum pumping for 3-5 minutes.

7.Pouring

Pour the mixture into the frame from a corner, make the silicone rubber flow to the frame smooth.

8.Demoulding

After 3-5 hours, you can demould the silicone mold. We suggest to put the silicone mold into production after 24 hours.
