Using instructions of liquid RTV silicone rubber:
If the customer wants to make large products and large size molds, the mold should be made of silicon rubber with high hardness. On the contrary, if the mold with fine and precision  patterns, it should be made of silicon with low hardness.

Frequently asked questions of  liquid RTV 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:

1   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;

 2 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.
