    4. Silicone rubber for gypsum mold making frequently asked question:

    Why does the silicone molds appeared striately and unsmoothly?

    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.

    To recommend suitable product for your application, we would be much appreciated to have your following information:

    1. What is the material of your product?

    2. What is the size of your product?

    3. How do you make silicone mold, by pouring or brushing?
