        FOUNDRY MOLDING SILICONE RUBBER DESCRIPTION:(LINK)
        It is the two-component condensed room temperature curing liquid silicone rubbers, consisted of Part A and B. part the mixed ratio is from 100: 2 to 100: 5 (large adjustment range of hardness), mainly be suitable for making molds application. .we have different items of different hardness, viscosity and curing time to cater to different users' requirements. Users can use it for different operations like pouring molds and brushing molds etc.


        FOUNDRY MOLDING SILICONE RUBBER APPLICATION:
        *Polyester arts and crafts, polyurethane statuary, ceramic statues
        *Artificial stone, concrete block, ornamental concrete, ornamental plaster, cement constructions, GRC building decorations, GRP products
        *Model design, product exploitation, etc.

        FOUNDRY MOLDING SILICONE RUBBER FEATURES:
        1.No-deformation and high degree of precision in reproduction 
        2.Excellent tensile and tear strength ,Favorable tension, low shrinkage
        3.Low linear shrinkage
        5.Easy for operation (mixing ratio from  100:2 to 100:5)
        6.Excellent non-stick effect  ,non-Oily
        7. Suitable for pouring molding and brushing molding

        FOUNDRY MOLDING SILICONE RUBBER OPERATION:
        Artificial Hill Molding Silicone OPERATION:
        Step 1: prepare the original molds 
        Prepare an perfect mold model and clean it totally(the release agent can be detergent, soapy water and Vaseline)before operation .Take 100g silicone material and 2~5g curing agent strictly and mix them evenly. 
        *Notes:Make sure the toys and operation tool cleaned up totally to avoid uncure problem .
        Step 2: Vacuum pumping
        Without exception, this step takes less than 10 minutes.(normally is 5munites) Otherwise, it will cause cross linking reaction, and no more further steps will be available.
        Step 3: Pouring casting or Brushing operation
        1. For simple pattern products we suggest use pouring operation way, which will be very easy to operate and demould. Pourable silicone require light viscosity which will be easy to flow smoothly and easy to de-air . (mold with fine and precision  patterns with low hardness.)
        2.For delicate pattern products we suggest use brushing operation way.which can copy the pattern exactly .brushing way require high viscosity which won’t be easy to flow away and easy to brush .(large size molds with high hardness)
        3
        .The amount of the curing agent can be adjusted according to the actual requirements of the customer If molds requiring fast drying and demold, more curing agent is needed; contrarily, if molds requiring slower drying and demold, less curing agent is needed.but we do not suggest to add silicone oil avoid oil problem.
        Step 4:Demoulding:
        After 35 hours later, can demould the silicone mold,It’s will be better for mold to demould after 24 hours
        Notes:The curing temperature and curing time can be adjustable according to the operation conditions.
