Liquid silicone rubber for concrete molds making

The material of molds used in the production of concrete products should be carefully selected. The liquid silicone rubber can perfectly meet the requirements. we can use the technology of RT (Rapid Tooling) to accomplish reproduction. To make a silicone rubber mold for concrete products is not so difficult. The production cycle is very short, which is suitable for volume-production, leading to remarkable economic benefits. As a result, a lot of manufacturers think highly of liquid silicone rubber for concrete molds making.       Liquid silicone rubber is a kind of ideal material for RT technology. Silicone rubber mold can be directly removed after the completion of the production. It can cast for the concrete products with complex structure, fine decorative pattern, as well as deep groove parts.   The main component of liquid silicone rubber for concrete molds making is silicon dioxide. Its structure is very much like a sponge which can absorb and water. Under the humidity condition of 100%, it can absorb and condense 40% water vapor.   Uses of liquid silicone rubber: This kind of material is mainly applicable to concrete products, crafts, decorative parts, gifts, POLI handicraft, resin handicraft, candles and other products with complex designs.   Operating suggestions of liquid silicone rubber: There are three ways to make craft molds, and they are pouring method, wrapping method and brushing method. Liquid molding silicone rubber is kind of flowing liquid, which consists of two components: one part is base silicone and the other part is the curing agents. The mixing ratio for condensation type silicone is 100:1, while for addition cure type silicone is 1:1 or 10:1. Mix the two parts of the whole set evenly. Then, take the mixture to de-air for 3-5 minutes.   Hong Ye Jie technology Co. Ltd is persistently supplying liquid silicone rubber for concrete molds making. Fully meeting customers’needs is what Hongye staff always try to accomplish with all the forces.
