Why does mold silicone have a low number of mold turnovers?

In the process of making the mold added too much silicone oil, silicone oil destroyed the molecular weight of silica gel, so the mold will appear to turn the mold less times not durable and other phenomena. If it is said to do small products with more complex patterns, with hardness of silicone to open the mold, there will be less mold turning times, because the silicone too hard time will be very brittle and easy to break. On the contrary, if you do build products and use silicone with little hardness to do the mold, the result will be equally unsatisfactory. Because the silicone is too soft, its tensile and tear strength will be reduced, and the mold made will be deformed, so the number of mold turning will be reduced. The quality of the mold adhesive itself is very good, there is no good or bad silicone, only suitable and unsuitable. We have to use the silicone suitable for the hardness of the product size to make the mold will not appear this situation.
