During the process of making silicone molds, we recommend that customers do not add any silicone oil. If necessary, the maximum amount of silicone oil added should not exceed 5% to 10%. Because excessive addition of silicone oil can damage the molecular weight of silicone, resulting in molds that are not resistant to acid, alkali, or aging.

Why does the mold made by the rubber Injection molding machine have traces, stripes and unsmooth surface?

This phenomenon occurs because the product or model to be replicated has not been polished or polished. Because the actual model or product itself is not smooth or perfect enough, if the product or model to be copied has not been polished or polished, even a good silicone mold will be unattractive and not smooth enough. Another situation is that when applying the release agent, not applying it evenly can also cause the mold to be unsmooth.
