First is the choice of Silicone Mould Material, generally choose high quality silicone rubber, which consistent with the following characteristics?
1.Silicone Moulding Rubber has good operation performance.
2.The fluidity of silicone rubber is suitable, the viscosity is moderate, and easy to brush mould.
3.The smaller the shrinkage of silicone rubber, the better.
4.The silicone tension is good.
Secondly, according to the different products add different dosage of silicone oil or not add, because silicone oil will destroy the molecular weight of silicone gel, resulting in reducing the number of turns.
Thirdly is to avoid improper operation in the production process, comparison of silica gel and curing agent ratio. Improper operation is easy to break or even scrap silicone rubber mold.
