1. Why silicon rubber mold will appear less turning model number?
Mold in the production process of adding too much silicone oil, silicone oil destroyed the molecular weight of the silica, so the mold will be turning model of fewer non-durable and so on. If the products do little more complex pattern of products, with a large open-hardness silica occurs turning model of fewer phenomenon, because the silicone perfect time will be very brittle, easily broken. Conversely, if you do build products with a small hardness silicone mold to do, the result will also be unsatisfactory. Because the silicone is too soft, it will reduce the tensile and tear strength, made out of the mold will be deformed, so turning model number will be reduced. Silicone mold itself are very good quality, silicone not good or bad, only the fit and do not fit. To be used for product hardness silicone to make the mold size does not appear the situation.
2. Why silicon rubber mold will be burning mode phenomenon?
Because unsaturated resin and the resin product plus a peroxide curing agent after the reaction resin case will generate a lot of heat, general resin curing time of 3 minutes, so 3 minutes to release as soon as possible, we will not be able to prevent the silicone mold produce burning mode phenomenon.
3. Why silicone rubber mold will appear in the table dry quit phenomenon?
Silicone mold belongs condensation silicone, it is by absorbing moisture from the air and cured silicone in the process of making, the water evaporated, the transferred amount without water, there will be surface dry Lane quit phenomenon. Solution: This phenomenon does not belong to product quality issues, but because there is no control of water, lifting silicone shelf life, shelf life for a long time to appear these phenomena, as long as when using silica gel, adding an appropriate amount of 0.05% of water, stir it you can solve some of the situation.
4. Why silicone rubber mold will appear the phenomenon of poor tension?
Because the customer in the production process of the mold in order to reduce the viscosity of the silicone, silicone easy to make large amounts of silica in a silicone oil is added, which would make the silica gel becomes soft, tensile produce intolerance, reduced tear strength, Rally deterioration phenomenon, resulting mold is not durable, life is short, less turning model number and so on.
5. Why does the silicone rubber mold will appear Maoyou situation?
Silicone mold itself is not Mao, there Maoyou because during operation adds composite silicone oil (silicone oil and white mineral oil complex ligand) as white mineral oils are petrochemical products, not silicone.
6. Why mold will produce acid, intolerant aging phenomenon?
In the process of making silicone mold, and recommends the best customer without any silicone oil, if desired, the amount of silicone oil added up to no more than 5% to 10%. Because of the excessive amount of silicone oil will destroy the molecular weight of the silica, so out of the mold will produce acid, intolerant aging phenomenon.
