what to do if silicone mold has few reproducing ti...

a. It might due to you adding too much silicone oil into silicone rubber. Silicone oil is an additive which destroies the molecular weight of silicone rubber and reduce the tension and tear strength of silicone rubber. b. Didn't use the suitable silicone for different products.   If using silicone rubber with a high hardness to make molds for small sized products with delicate and intricate designs, the silicone will be difficult to demould becuase of fine details on the products.  and the silicon rubber with a low hardness to makes molds for large sized products with simple designs.   c. Don't add too much silicone oil into silicone rubber when making molds. If fact, the tension and the tear strength will be reduced badly when you add silicone oil over 30% of the silicone.  And the silicone molds will be in a weak and flimsy manner.
