Silicone Rubber Moulding itself is not taking oil, oil is appearing because of adding the composite silicone oil during operation. Why the silicone for molds will produce acid and alkali, aging phenomenon? In the process of Silicone Rubber for Mold Making, we recommend customers do not add any silicone oil, if necessary, the amount of silicone oil should not exceed 5% to 10%. because the excessive amount of silicone oil will destroy the molecular weight of silica gel, so the mold is not acid and alkali resistance.
Why the mold made of silica gel surface will appear traces, stripes, not smooth?
This is due to the copied product or model has not been polished. Because the model or the product itself is not smooth, the product to be copied, if not polished, a good silicone mold will be unsightly, not smooth enough. When the mold release agent, no uniform brushing will also cause the mold rough.
