How long will a silicone mold last?Updated 23 days ago
Many factors need to be taken into consideration, so this is difficult to answer with a specific time. The primary factors that play a role in the life of a silicone rubber are what the rubber is being used for, what casting medium is being used, how large is the mold, what is the severity of undercuts, how is it stored, as well as the type of silicone being used for the application. Yields can vary from a single part or two to hundreds or even thousands. Average mold life expectancy for a simple 1 or 2 piece urethane casting average between 30-70 pulls depending on the specific factors involved.
