Hongye  mold making RTV-2 silicon rubber operations

If the customer wants to make large products and large size molds, the mold should be made of silicon rubber with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of silicon with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If molds requiring fast drying and demold, more curing agent is needed; contrarily, if molds requiring slower drying and demold, less curing agent is needed.

(Note: our company does not recommend you to add silicone oil. If a special soft silicone mold or fine detailed and complex patterns products are required, 5%-10% silicone oil can be added to soften the mold for easy demold.)

Frequently asked questions of molding silicone rubber

Why is the appearance of the finished mold striate and unsmooth?

It is because the appearance of the product or the model itself is not perfect, and it has not been polished before the further operation. So when you make silicon molds, firstly you should polish the product, spray the mold spray evenly on the product. In this case, the problem can be avoided.

Why isn’t the silicon mold acid & alkali and aging resistant?

It is due to the addition of the silicon oil. Normally we do not advise our customers to add any silicon oil into the silicon rubber. If it is necessary, the ratio must be 5%-10%.
