Two-component mold silica gel can also be called RTV-2 silica gel, which can be divided into room temperature silica gel and high temperature silica gel. It is mainly used for making molds and potting two-component mold silica gel. It is mainly used for toys, craft gifts, fine patterns, Die molds, infusion mold products, POLI crafts, resin crafts, lighting, candles and other crafts complex molds and precision mold manufacturing. Pad printing silicone use: Pad printing silica gel for plastic toys, PVC toys, craft gifts, electronic products, lighting, plastic toys, electroplating products, electronic toys, trademarks, irregular pattern printing and other silicone. Hand Silicone Use: Used to make hand model design, PVC plastic mold, cement product mold, melting alloy mold, alloy toy craft, plastic toy crafts, gift stationery, large statue, cultural relic copy, sole mold manufacturing, printing positioning, electronic equipment Earthquake resistance, etc. Large-size products, hand model design, electronic product positioning, model design, the number of molds is about 5-10 times, is used to make simple pattern products, toys, car two-component mold silicone.
In the process of making the mold, too much silicone oil is added, and the silicone oil destroys the molecular weight of the silica gel, so the mold will have a phenomenon of less mold turning and less durability. If you say that the product with a small product pattern is more complicated, and the mold with a high hardness is used to open the mold, there will be a phenomenon of less mold turning, because the time when the silica gel is too hard will be very brittle and easy to break. On the contrary, if you build a product and use a low-hardness silica gel to make the mold, the result will be unsatisfactory. Because the 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 overturning will be reduced. The quality of the mold glue itself is very good, the silicone is not good or bad, only suitable and not suitable. We don't want to use a silicone that is suitable for the hardness of the product to make the mold.
