1, in the production of mold process to add too much silicone oil, silicone oil damage to the molecular weight of silicone, so the mold will be less than the number of times the number of turns, and so on.
2, if small veins more complex products, mold with high hardness silicone, will appear over the phenomenon of less number of, because excellent silicone time will very brittle, easily broken. On the contrary, if with low hardness silicone mold to do large products, it will also be less satisfactory. Because silicone soft, its tensile and tear strength will be reduced, made out of mold will be deformed, so turn mode frequency will be reduced. Mold plastic itself is very good quality, silicone is not good or bad, only suitable and not suitable for. We should adopt the suitable product hardness size silicone to make the mold does not appear this kind of situation.
