Many customers find that silicone mold transformation when they use silicone rubber to make silicone molds. Silicone rubber with low hardness has the characteristic of ease of deformation. How to avoid the silicone molds transformation? Let’s analyze it in five aspects as below: 1. Put it into production before it does not cure completely. Although the silicone mold can be demold a few hours after casting mold. The silicone mold cures completely take less than 24 hours. If time permits, experienced people usually de-mold the mold and put it into production 24 hours after casting molds. 2. The quality of the silicone rubber is poor, or the shrinkage is too high or the filler is too many. The shrinkage of high-grade silicone rubber is about 0.1%, the shrinkage of ordinary silicone rubber is about 0.3%. The shrinkage of poor silicone rubber is higher. 3. The lining shell of silicone rubber does not accurate. 4. Do not put the soft silicone mold into the hard lining shell to save time aft
