1. Why does the mold silica gel have fewer re-molding times? Too much silicone oil is added in the process of making the mold, and the silicone oil destroys the molecular weight of the silica gel, so the mold will have fewer re-molding times and not durable. If it is said that a small product with a more complex pattern is used to open the mold with a high-hardness silica gel, there will be less times of mold reversal, because the silica gel will be brittle and easy to break when it is too hard. On the contrary, if you use low-hardness silicone to make molds for building products, the result will also be unsatisfactory. Because silica gel is too soft, its tensile strength and tear strength will be reduced, and the resulting mold will be deformed, so the number of mold turns will be reduced. The quality of the mold glue itself is very good, and there is no good or bad silicone, only suitable and unsuitable. We have to use silica gel suitable for the hardness of the product to make the mold and this situation will not occur. 2. Why does the mold glue appear to burn? Because unsaturated resins and resin products are added with peroxide curing agents, they will react with the resin to generate a lot of heat. Generally, the curing time of the resin is 3 minutes, so after 3 minutes It is necessary to demold as soon as possible to prevent the silicone mold from burning. 3. Why does the mold glue appear to dry on the surface and not dry inside? Mold silicone is a condensation type silica gel, which is cured by absorbing moisture in the air. During the process of making the silicone, the moisture is evaporated to dryness , And this phenomenon occurs without adding the right amount of water. Solution: This phenomenon is not a product quality problem, but because there is no water control, and the storage period of the silica gel is increased, and the shelf life is long. When using silica gel, add an appropriate amount of 0.05% water and mix well. Some situations can be resolved. 4. Why is there a phenomenon of poor tension in the mold glue? Because in the process of making the mold, the customer adds a large amount of silicone oil to the silicone in order to reduce the viscosity of the silicone and make the silicone easy to handle. This will make the silicone very difficult. It is soft, resulting in the phenomenon of inability to withstand tension, reduced tearing strength, and deterioration of tensile force, resulting in molds that are not durable, short in service life, and fewer times of turning over. 5. Why does the mold appear to be oily? The mold silicone itself does not emit oil. The oil Mould suppliers is caused by the addition of compound silicone oil (a compound of silicone oil and white mineral oil) during the operation, because of white mineral oil It is a petrochemical product, not a silicone oil. 6. Why is the mold not resistant to acid and alkali and aging? In the process of making silicone molds, we recommend that customers do not add any silicone oil. If necessary, the amount of silicone oil should not exceed 5%~10%. . Because excessive addition of silicone oil will destroy the molecular weight of silica gel, the resulting mold will not be resistant to acids and alkalis and aging.
