    Buyer Feedback



    1. Why should the silicone mold be reused only for a few times?
    It can be due to the following reasons:
    A. Adding too much silicone oil in to silicon rubber. Silicon oil is an additive which destroies the molecular weight of silicone rubber and reduce the tension and tear strength.
    B. Using the silicon rubber with a high hardness to make molds for small sized products with delicate and intricate designs and the silicon rubber with a low hardness to makes molds for large sized products with simple designs.
    (Notes: we should choose the silicon rubber specifically according to the requirements of our products to avoid this problem.)

    2. The solutions of the sticky of the rubber silicone RTV-2 mold?

    A.The main reason for this problem is that you do not handle the products or original molds well, then you should deal with the original mold or products carefully before molding. Such as for the products with a complicated pattern or a unsmoothed surface, you should polish and clean the products after which it will be molded ,then spray the release agent.

    Normally, the release agent can be Vaseline , detergent. liquid wax Etc. In practical process, you can brush different release agent according to different material.

    B.The second reason is that the operator pour the silicone into the mold when the mixture is mixed evenly, then the finish silicone mold will partialy cured.
