Datasheet of silicone rubber for mold making-for casting poly resin:

Using Guidance of silicone rubber for mold making-for casting poly resin:

(1) Take out a certain amount of liquid silicone base (part A)from the container;

(2) Take out a certain amount of liquid silicone base (part B) from the container and mix with part A.

(3) The two components of silicone rubber must be mixed homogeneously, otherwise, it will be partly cured and solidified;

(4) Deaerate in a vacuum cupboard to achieve bubble free vulcanization;

(5) Pouring the deaerated mixture over the highest point of the model to form castingmould;

(6)  Demolding after the liquid silicone solidified thoroughly.

(7) The mixed liquid silicone rubber will solidified in 3-4 hours under room temperature.

Frequently asked questions of  silicone rubber for mold making:

Why does the silicone rubber mold have few molding times?

The silicone rubber moldhas few molding times is due to follwoing reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products.
