Why silicone mold be reused only for a few times?

 

1. This may be due to the following reasons: 1) Adding too much silicone oil to silicone rubber, silicone oil is a Supplement that violates the molecular weight of the silicone rubber and reduce the tension and tear strength.

2. The use of silicone rubber with high hardness to make molds for small products with delicate and intricate line and silicone rubber with low hardness making the mold for large products with a simple design.

(Note: we must choose silicone rubber specifically in accordance with the requirements of our products, in order to avoid this problem)

 

3. Why silicone molds are annealed yavleniya?

This is because you have left out important notes when using materials of unsaturated resins for the production of Your products, Unsaturated resin produces great heat, adding hardener. So you have to pour the product from the mold for 3 minutes, in order to avoid this problem.
