Silicon rubber for mold making operation instructions
Step One: Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.
Step Two: vacuum pumping
Without exception, this step takes less than 10 minutes.
Note: The time for vacuum-pumping should be less than 3—5 minutes ,otherwise, once the silicone rubber has cross-link reaction during vacuum pumping process, it will not be operated.
Step Three: Brushing cast & Perfusion Molding operation
Shelf life for silicon rubber for mold making
10~12months, when stored in a dry & cool place under the room temperature 25.

Frequently asked questions of molding silicone rubber
Why does the silicone rubber mold have few molding times?
The silicone rubber mold has 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.
