Can a mold made of liquid silicone be used for reversal of the mold?

Someone asked, can liquid silicone turn over the silicone mold? How did you turn it over? Today I will tell you some tutorials on using liquid silicone to turn over silicone molds. Many people know that liquid silicone has high and low temperature resistance, aging resistance, thermal stability, tear resistance, resilience, and fast vulcanization. Safety and environmental protection and other advantages. If we are producing soap, but currently there is only one soap, should we be busy making it? Freezing three feet is not a day’s cold. Only when you experience it yourself can you understand the mystery of making silicone rubber molds. In order to better save the cost of the enterprise, the editor will show you how to make soap soap with silicone rubber. Silicone rubber mold. 1. Preparation of materials According to the characteristics of the products you want to make, choose the appropriate hardness of Hongye high transparent mold silica gel, one mold type, one electronic scale, one mixing container, one mixing knife and other tools and materials. 2. Treatment of soap and soap molds After polishing and smoothing the molds, apply the release agent evenly (the mold release agent can be petroleum jelly, liquid paraffin, detergent, soapy water, etc.), and blow dry with a hair dryer or dry with gauze . If you want to make a split mold, you must choose to draw the mold line. Reminder: If the mold release agent is not evenly applied, it will cause some complex patterns where the mold release agent cannot be applied during mold release. 3. Fixing the mold type Use glue to fix the mold type on the wooden board, and deal with the mold type according to the different mold opening methods. Specifically, there are injection molds, overmolds, and split mold opening methods. 1. Splitting mold: Pile up the part below the mold line with oil sludge, smooth it and cut it off with a knife, preferably 1cm-1.5cm away from the mold. 2. Pouring mold: Pouring mold or pouring mold is used for relatively smooth or simple products. There is no mold line to save labor and time, that is, the product or model you want to copy is surrounded by plastic or glass plates and glued. Seal the surroundings to prevent the silicone rubber from flowing out along the gap when the high-transparent mold silicone is poured into the gap. Reminder: release agent should be used where the rubber plate or glass plate is in contact with the silicone rubber. 4. The ratio of silicone rubber and curing agent to estimate the amount of mold. The appearance of highly transparent mold silicone is a flowing liquid, and component A is odorless silicone. , The B component is a curing agent. Use electronic weighing to weigh the required silica gel, and then weigh the curing agent according to a certain proportion. Generally, the addition amount of the curing agent is 2%-3%. The curing agent must be stirred evenly, and then vacuumed to remove air bubbles. 5. The operation process of high-transparent mold silica gel is generally carried out by painting or pouring operation, which is mainly divided into: pouring mold, overmolding, and splitting mold. 1. The operation method of filling or pouring mold: After fixing the mold, pour the evacuated silicone rubber directly onto the product. After the odorless silica gel is dried and formed, the product is taken out and the mold is formed (Note: Infusion molds are generally made with softer reversing mold glue, so that it is easier to demold and will not damage the products in the silicone rubber mold). 2. Overmold or split mold operation method: Evacuate the air bubbles The odorless silica gel is applied by brushing or pouring. Pour it on top of the product (Note: The product or model to be copied before pouring the silica gel must be coated with a release agent or release agent). Then apply high-transparent mold silicone on the top of the product. The painting must be even. After 30 minutes, paste a layer of gauze and fiber weft cloth to increase the strength and tension of the odorless silicone. Then apply a layer of silicone rubber, and then paste a layer of gauze fiber weft cloth, so that it will be fine after two times. Only by doing so, the service life of the red leaf odorless silicone mold and the number of mold turning times will be relatively increased, which can save costs and improve efficiency. If it is a large product, glass fiber cloth can also be pasted, but the glass fiber cloth cannot be pasted on the first layer, because it is hard and the inside of the mold will not be smooth. 3. Production of outer mold: (1) Adopt resin painting method, apply a layer of resin and paste a layer of glass fiber cloth, then paint and paste, repeat two or three layers to complete the mold outer mold. (2) The generally used method and material is to surround the mold with rubber sheets or wooden boards, and fill the mold cabinet with plaster. Note: After the silicone rubber mold is finally completed, it will be decided according to the product characteristics. Whether to cut the mold, if it is cut, it is saw-toothed.
