Why does mold silicone turn over less frequently and is not durable?

If the mold silicone is turned over less often and is not durable, it is likely that too much silicone oil is added during the mold making process. The silicone oil destroys the molecular weight of the silicone, so the mold will be turned over less often and is not durable. If you want to make small products with complex patterns, if you use hard silicone to open the mold, the mold will be turned over less often, because the silicone will become brittle and easy to break when it is too hard. On the contrary, if you build a product and use silicone with low hardness to make the mold, the result will also be unsatisfactory. Because silicone is too soft, its tensile and tear strength will be reduced, and the mold will be deformed, so the number of mold turnovers will be reduced.
 
In addition, there is no choice of good quality mold silica gel. There are many types of mold silica gel and there are many manufacturers. In order to increase profit margins, many traders will add some weight-increasing powder to the mold silica gel to reduce costs. There are also some manufacturers that use recycled raw materials for secondary production, which will affect the product quality of mold silicone.
