FAQs in the use of the mold making silicone rubber

1. Why does the silicone rubber mold have few molding times?

       The silicone rubber mold has few molding times is due to following reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products. 

2. Why does the mold made of silicone rubber have an unsmooth surface with tracks and strips on it?

　　It is due to product or model to be molded should hasn't been sanded or polished . If the mold or product is not sanded or polished, the mold made of whatever quality silicone rubber will not be good and smooth enough since the model or the product itself is not smooth or perfect. Another case is that uneven brushing of the release agent will also make the mold unsmooth.
